Defined in usdrt/scenegraph/usd/usd/impl/usd_decl.h

Structs

• iterator: A forward iterator into a UsdPrimRange .

class UsdPrimRange

a forward-iterable range that traverses a subtree of prims rooted at a given prim in depth-first order.

TODO Usage example TODO iterator needs more doc details…

Note

post-visit iterators not yet supported.

Public Functions

inline UsdPrimRange()

UsdPrimRange(const UsdPrim &start)

Create a PrimRange that traverses the subtree rooted at start in depth-first order.

Parameters

start – UsdPrim to use as root of traversal.

iterator begin() const

Return an iterator to the start of this range.

iterator end() const

Return a past-the-end iterator to the end of this range.

bool empty() const

Check if this range is empty.

Returns

Return true if this range contains no prims, and false otherwise.

explicit operator bool() const

Returns

Return true if this range contains one or more prims, false otherwise.
