	)

pure virtual

Adds a variant to the module.

Parameters

name	The simple name of the material or function variant.
prototype_name	The DB name of the prototype of the new variant.
defaults	Default values to set. If `NULL`, the defaults of the original material or function are used. Feasible sub-expression kinds: constants and calls.
annotations	Annotations to set. If `NULL`, the annotations of the original material or function are used. Pass an empty block to remove all annotations.
return_annotations	Return annotations to set. If `NULL`, the annotations of the original material or function are used. Pass an empty block to remove all annotations. Materials require `NULL` or an empty annotation block here.
is_exported	Indicates whether the variant will have the 'export' keyword.
is_declarative	Indicates whether the variant will have the 'declarative' keyword.
context	The execution context can be used to pass options and to retrieve error and/or warning messages. Can be `NULL`.

^◆ analyze_uniform()

virtual const IArray * mi::neuraylib::IMdl_module_builder::analyze_uniform	(	const IExpression *	root_expr,
		bool	root_expr_uniform,
		IMdl_execution_context *	context
	)

pure virtual

Analyzes which parameters need to be uniform.

Note that the method can fail if the graph to be analyzed is invalid and/or never uniform independent of uniform modifiers of parameter types.

root_expr_uniform is `false`	root_expr_uniform is `true`	Interpretation
failure	failure	The graph is invalid.
failure	success	This case is not possible.
success	failure	The graph is never uniform.
success	success	The graph is uniform if the parameters returned in the `true` case are made uniform.

If the graph should be uniform, and you cannot rule out invalid graphs, then you might want to invoke this method first with root_expr_uniform set to false to check for validity. If that method succeeds, you can then call it again with root_expr_uniform set to true to obtain the constraints on the parameters.

Parameters

root_expr	Root expression of the graph, i.e., the body of the new material or function. Feasible sub-expression kinds: constants, direct calls, and parameter references.
root_expr_uniform	Indicates whether the root expression should be uniform.
context	The execution context can be used to pass options and to retrieve error and/or warning messages. Can be `NULL`.

Returns: Returns an array of boolean values indicating which parameters need to be uniform (or NULL in case of errors). The array indices match the indices of the parameter references. The array might be shorter than expected if trailing parameters are not referenced by root_expr.

^◆ clear_module()

virtual Sint32 mi::neuraylib::IMdl_module_builder::clear_module ( IMdl_execution_context * context )

pure virtual

Clears the module, i.e., removes all entities from the module.

^◆ remove_entity()

virtual Sint32 mi::neuraylib::IMdl_module_builder::remove_entity	(	const char *	name,
		Size	index,
		IMdl_execution_context *	context
	)

pure virtual

Removes a material, function, enum or struct type from the module.

Parameters

name	The simple name of material, function, enum or struct type to be removed.
index	The index of the function with the given name to be removed. Used to distinguish overloads of functions. Zero for materials, enum or struct types.
context	The execution context can be used to pass options and to retrieve error and/or warning messages. Can be `NULL`.

^◆ set_module_annotations()

virtual Sint32 mi::neuraylib::IMdl_module_builder::set_module_annotations	(	const IAnnotation_block *	annotations,
		IMdl_execution_context *	context
	)

pure virtual

Sets the annotations of the module itself.

Parameters

annotations	Annotations of the module. Pass `NULL` to remove existing annotations.
context	The execution context can be used to pass options and to retrieve error and/or warning messages. Can be `NULL`.
