Detailed Description

Base class for custom stage traversal.

To register traversals, define a static GusdUSD_TraverseType singleton that takes an instance of the traverse object.

UsdTimeCode  time,

bool  skipRoot = true,

) const
pure virtual

Find prims beneath the given root.

Implemented in GusdUSD_TraverseSimpleT< Visitor >.

virtual bool GusdUSD_Traverse::FindPrims ( const UT_Array< UsdPrim > &  roots,
const GusdDefaultArray< UsdTimeCode > &  times,
const GusdDefaultArray< GusdPurposeSet > &  purposes,
UT_Array< PrimIndexPair > &  prims,
bool  skipRoot = true,
const Opts *  opts = nullptr 
) const
pure virtual

Find prims beneath the given root prims. Note that the input array of prims may contain invalid prims. The returned prims array holds the new prims, and the index of their root prim from the roots array. The array is sorted by the index and the prim path.

Implemented in GusdUSD_TraverseSimpleT< Visitor >.
