Function Documentation

SdfSpecDynamic_cast()

SdfHandle<typename DST::SpecType> SdfSpecDynamic_cast ( const SdfHandle< SRC > &  x )

inline

Convert SdfHandle<SRC> x to an SdfHandle<DST>.

This function is similar to TfDynamic_cast, but it allows the SRC and DST spec to be indirectly related, so long as the schema associated with the DST spec type is a subclass of the schema associated with x.

Definition at line 294 of file declareHandles.h.

SdfSpecStatic_cast() [1/2]

SdfHandle<typename DST::SpecType> SdfSpecStatic_cast ( const SdfHandle< SRC > &  x )

inline

Convert SdfHandle<SRC> x to an SdfHandle<DST>.

This function is similar to TfStatic_cast, but it allows the SRC and DST spec to be indirectly related.

Definition at line 312 of file declareHandles.h.

SdfSpecStatic_cast() [2/2]

DST_SPEC SdfSpecStatic_cast ( const SRC_SPEC &  x )

inline

Convert SRC_SPEC to a DST_SPEC.

Definition at line 323 of file declareHandles.h.

TfDynamic_cast()

SdfHandle<typename DST::SpecType> TfDynamic_cast ( const SdfHandle< SRC > &  x )

inline

Convert SdfHandle<SRC> x to an SdfHandle<DST>.

This function behaves similar to a dynamic_cast. If class DST cannot represent the spec pointed to be x, or if the classes DST and SRC are not directly related to each other in the C++ type hierarchy, the conversion fails and an invalid handle is returned.

XXX: The second condition in the above statement is currently untrue. This function will allow casting between spec classes even if they are not directly related. Doing so could lead to schema mismatches and other buggy behavior.

Definition at line 242 of file declareHandles.h.

TfStatic_cast()

SdfHandle<typename DST::SpecType> TfStatic_cast ( const SdfHandle< SRC > &  x )

inline

Convert SdfHandle<SRC> x to an SdfHandle<DST>.

This function behaves similar to a static_cast. No runtime checks are performed to ensure the conversion is valid; it is up to the consumer to ensure this.
