Member Function Documentation

Get() [1/2]

static HD_API HdDataSourceBaseHandle Get ( const Handle &  container, const HdDataSourceLocator &  locator  )

static

A convenience function: given container, return the descendant identified by locator, which may be at any depth.

Returns container itself on an empty locator, or null if locator doesn't identify a valid descendant.

Get() [2/2]

virtual HdDataSourceBaseHandle Get ( const TfToken &  name )

pure virtual

Returns the child datasource of the given name.

This call is expected to be threadsafe.
