mi::neuraylib::IFunction_definition Class Reference

[MDL-related elements]

Description

This interface represents a function definition. A function definition describes the formal structure of a function call, i.e. the number, types, names, and defaults of its parameters, as well as its return type. The create_function_call() method allows to create function calls based on this function definition.

Note:
  • This interface also supports materials, which are considered as a special kind of functions, namely functions with the return type "material".

  • See Template-like function definitions for function definitions with special semantics.

Member Functions

virtual IFunction_call* mi::​neuraylib::​IFunction_definition::create_function_call( const IExpression_list* arguments, Sint32* errors = 0) const [pure virtual]

Creates a new function call.

Parameters

arguments
The arguments of the created function call. Arguments for parameters without default are mandatory, otherwise optional. The type of an argument must match the corresponding parameter type. Any argument missing in arguments will be set to the default of the corresponding parameter. Note that the expressions in arguments are copied. This copy operation is a deep copy, e.g., DB elements referenced in call expressions are also copied. NULL is a valid argument which is handled like an empty expression list.
errors
An optional pointer to an mi::Sint32 to which an error code will be written. The error codes have the following meaning:
  • 0: Success.
  • -1: An argument for a non-existing parameter was provided in arguments.
  • -2: The type of an argument in arguments does not have the correct type, see get_parameter_types().
  • -3: A parameter that has no default was not provided with an argument value.
  • -4: The definition can not be instantiated because it is not exported.
  • -5: A parameter type is uniform, but the corresponding argument has a varying return type.
  • -6: An argument expression is not a constant nor a call.
  • -8: One of the parameter types is uniform, but the corresponding argument or default is a call expression and the return type of the called function definition is effectively varying since the function definition itself is varying.
  • -9: The function definition is invalid due to a module reload, see is_valid() for diagnostics.
  • -10: The definition is non-declarative and at least one of the arguments is a declarative call.

Returns

The created function call, or NULL in case of errors.

virtual const IAnnotation_block* mi::​neuraylib::​IFunction_definition::get_annotations() const [pure virtual]

Returns the annotations of the function definition itself, or NULL if there are no such annotations.

virtual const IExpression* mi::​neuraylib::​IFunction_definition::get_body() const [pure virtual]

Returns the expression that represents the body of the function (if possible).

Note:
  • Functions bodies with control flow can not be represented by an expression. For such functions, this method always returns NULL. For all other functions, i.e., for functions, whose body is an expression or a plain return statement, the method never returns NULL (unless there is no body at all, see below).

  • Functions with a known semantic, i.e., different from mi::neuraylib::IFunction_definition::DS_UNKNOWN, do not have a body as such, and the method returns NULL for such functions.

virtual const IExpression_list* mi::​neuraylib::​IFunction_definition::get_defaults() const [pure virtual]

Returns the defaults of all parameters.

Note:

Not all parameters have defaults. Hence, the indices in the returned expression list do not necessarily coincide with the parameter indices of this definition. Therefore, defaults should be retrieved via the name of the parameter instead of its index.

virtual const IExpression_list* mi::​neuraylib::​IFunction_definition::get_enable_if_conditions() const [pure virtual]

Returns the enable_if conditions of all parameters.

Note:

Not all parameters have a condition. Hence, the indices in the returned expression list do not necessarily coincide with the parameter indices of this definition. Therefore, conditions should be retrieved via the name of the parameter instead of its index.

virtual Size mi::​neuraylib::​IFunction_definition::get_enable_if_user( Size index, Size u_index) const [pure virtual]

Returns the index of a parameter whose enable_if condition might depend on the argument of the given parameter.

Parameters

index
The index of the parameter.
u_index
The index of the enable_if user.

Returns

The index of a parameter whose enable_if condition depends on this parameter argument, or ~0 if indexes are out of range.

virtual Size mi::​neuraylib::​IFunction_definition::get_enable_if_users( Size index) const [pure virtual]

Returns the number of other parameters whose enable_if condition might depend on the argument of the given parameter.

Parameters

index
The index of the parameter.

Returns

The number of other parameters whose enable_if condition depends on this parameter argument.

virtual const char* mi::​neuraylib::​IFunction_definition::get_mangled_name() const [pure virtual]

Returns the mangled name of the function.

Note:

For materials, the mangled name is equal to get_mdl_simple_name().

Returns

The mangled name of the function definition.

virtual const char* mi::​neuraylib::​IFunction_definition::get_mdl_module_name() const [pure virtual]

Returns the MDL name of the module containing this function definition.

virtual const char* mi::​neuraylib::​IFunction_definition::get_mdl_name() const [pure virtual]

Returns the MDL name of the function definition.

Note:

The MDL name of the function definition is different from the name of the DB element. Use mi::neuraylib::ITransaction::name_of() to obtain the name of the DB element.

Returns

The MDL name of the function definition.

virtual const char* mi::​neuraylib::​IFunction_definition::get_mdl_parameter_type_name( Size index) const [pure virtual]

Returns the type name of the parameter at index.

Note:

The type names provided here are substrings of the MDL name returned by get_mdl_name(). They are provided here such that parsing of the MDL name is not necessary. Their main use case is one variant of overload resolution if no actual arguments are given (see mi::neuraylib::IModule::get_function_overloads( const char*, const IArray*)const. For almost all other use cases it is strongly recommended to use get_parameter_types() instead.

Parameters

index
The index of the parameter.

Returns

The type name of the parameter, or NULL if index is out of range.

virtual const char* mi::​neuraylib::​IFunction_definition::get_mdl_simple_name() const [pure virtual]

Returns the simple MDL name of the function definition. The simple name is the last component of the MDL name, i.e., without any packages and scope qualifiers, and without the parameter type names.

Returns

The simple MDL name of the function definition.

virtual void mi::​neuraylib::​IFunction_definition::get_mdl_version( Mdl_version& since, Mdl_version& removed) const [pure virtual]

Returns the MDL version when this function definition was added and removed.

Parameters

since
The MDL version in which this function definition was added. If the function definition does not belong to the standard library, the MDL version of the corresponding module is returned.
removed
The MDL version in which this function definition was removed, or mi::neuraylib::MDL_VERSION_INVALID if the function has not been removed so far or does not belong to the standard library.
virtual const char* mi::​neuraylib::​IFunction_definition::get_module() const [pure virtual]

Returns the DB name of the module containing this function definition. The type of the module is mi::neuraylib::IModule.

virtual const IAnnotation_list* mi::​neuraylib::​IFunction_definition::get_parameter_annotations() const [pure virtual]

Returns the annotations of all parameters.

Note:

Not all parameters have annotations. Hence, the indices in the returned annotation list do not necessarily coincide with the parameter indices of this definition. Therefore, annotation blocks should be retrieved via the name of the parameter instead of its index.

virtual Size mi::​neuraylib::​IFunction_definition::get_parameter_count() const [pure virtual]

Returns the number of parameters.

virtual Size mi::​neuraylib::​IFunction_definition::get_parameter_index( const char* name) const [pure virtual]

Returns the index position of a parameter.

Parameters

name
The name of the parameter.

Returns

The index of the parameter, or -1 if name is invalid.

virtual const char* mi::​neuraylib::​IFunction_definition::get_parameter_name( Size index) const [pure virtual]

Returns the name of the parameter at index.

Parameters

index
The index of the parameter.

Returns

The name of the parameter, or NULL if index is out of range.

virtual const IType_list* mi::​neuraylib::​IFunction_definition::get_parameter_types() const [pure virtual]

Returns the types of all parameters.

virtual const char* mi::​neuraylib::​IFunction_definition::get_prototype() const [pure virtual]

Returns the DB name of the prototype, or NULL if this function definition is not a variant.

virtual const IAnnotation_block* mi::​neuraylib::​IFunction_definition::get_return_annotations() const [pure virtual]

Returns the annotations of the return type of this function definition, or NULL if there are no such annotations.

virtual const IType* mi::​neuraylib::​IFunction_definition::get_return_type() const [pure virtual]

Returns the return type.

Returns

The return type.

template< class T>

const T* mi::​neuraylib::​IFunction_definition::get_return_type() const [inline]

Returns the return type. This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to call mi::base::IInterface::get_interface( const Uuid &) on the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Returns

The return type.

virtual Semantics mi::​neuraylib::​IFunction_definition::get_semantic() const [pure virtual]

Returns the semantic of this function definition.

virtual const IExpression* mi::​neuraylib::​IFunction_definition::get_temporary( Size index) const [pure virtual]

Returns the expression of a temporary.

Parameters

index
The index of the temporary.

Returns

The expression of the temporary, or NULL if index is out of range.

template< class T>

const T* mi::​neuraylib::​IFunction_definition::get_temporary( Size index) const [inline]

Returns the expression of a temporary. This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to call mi::base::IInterface::get_interface( const Uuid &) on the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Parameters

index
The index of the temporary.

Returns

The expression of the temporary, or NULL if index is out of range.

virtual Size mi::​neuraylib::​IFunction_definition::get_temporary_count() const [pure virtual]

Returns the number of temporaries used by this function.

virtual const char* mi::​neuraylib::​IFunction_definition::get_temporary_name( Size index) const [pure virtual]

Returns the name of a temporary.

Note:

Names of temporaries are not necessarily unique, e.g., due to inlining. Names are for informational purposes and should not be used to identify a particular temporary.

See also:

mi::neuraylib::IMdl_configuration::set_expose_names_of_let_expressions()

Parameters

index
The index of the temporary.

Returns

The name of the temporary, or NULL if the temporary has no name or index is out of range.

virtual const char* mi::​neuraylib::​IFunction_definition::get_thumbnail() const [pure virtual]

Returns the resolved file name of the thumbnail image for this function definition. The function first checks for a thumbnail annotation. If the annotation is provided, it uses the 'name' argument of the annotation and resolves that in the MDL search path. If the annotation is not provided or file resolution fails, it checks for a file module_name.material_name.png next to the MDL module. In case this cannot be found either NULL is returned.

bool mi::​neuraylib::​IFunction_definition::is_array_constructor() const [inline]

Indicates whether this definition represents the array constructor.

See also:

Arrays

virtual bool mi::​neuraylib::​IFunction_definition::is_declarative() const [pure virtual]

Indicates whether the function definition is exported by its module.

virtual bool mi::​neuraylib::​IFunction_definition::is_material() const [pure virtual]

Indicates whether the definition represents a material.

virtual bool mi::​neuraylib::​IFunction_definition::is_uniform() const [pure virtual]

Indicates whether the function definition is uniform.

Note:

This includes, in addition to functions definitions that are explicitly marked as uniform, also function definitions that are not explicitly marked either uniform or varying and that have been analyzed by the MDL compiler to be uniform.

virtual bool mi::​neuraylib::​IFunction_definition::is_valid( IMdl_execution_context* context) const [pure virtual]

Returns true if the definition is valid, false otherwise. A definition can become invalid if the module it has been defined in or another module imported by that module has been reloaded. In the first case, the definition can no longer be used. In the second case, the definition can be validated by reloading the module it has been defined in.

Parameters

context
Execution context that can be queried for error messages after the operation has finished. Can be NULL.

Returns

- true The definition is valid.

  • false The definition is invalid.
