| class | UsdSchemaRegistry |
Class representing the builtin definition of a prim given the schemas registered in the schema registry.
It provides access to the the builtin properties and metadata of a prim whose type is defined by this definition.
Instances of this class can only be created by the UsdSchemaRegistry.
Definition at line 47 of file primDefinition.h.
| USD_API bool FlattenTo | ( | const SdfLayerHandle & | layer, |
| const SdfPath & | path, | ||
| SdfSpecifier | newSpecSpecifier = SdfSpecifierOver |
||
| ) | const |
Copies the contents of this prim definition to a prim spec on the given layer at the given path.
This includes the entire property spec for each of this definition's built-in properties as well as all of this definition's prim metadata.
If the prim definition represents a concrete prim type, the type name of the prim spec is set to the the type name of this prim definition. Otherwise the type name is set to empty. The 'apiSchemas' metadata on the prim spec will always be explicitly set to the combined list of all API schemas applied to this prim definition, i.e. the list returned by UsdPrimDefinition::GetAppliedAPISchemas. Note that if this prim definition is an API schema prim definition (see UsdSchemaRegistry::FindAppliedAPIPrimDefinition) then 'apiSchemas' will be empty as this prim definition does not "have" an applied API because instead it "is" an applied API.
If there is no prim spec at the given path, a new prim spec is created at that path with the specifier newSpecSpecifier. Any necessary ancestor specs will be created as well but they will always be created as overs. If a spec does exist at path, then all of its properties and schema allowed metadata are cleared before it is populated from the prim definition.
