Usd_PrimFlagsPredicate | UsdTraverseInstanceProxies (Usd_PrimFlagsPredicate predicate) |
This function is used to allow the prim traversal functions listed under Prim predicate flags to traverse beneath instance prims and return descendants that pass the specified predicate as instance proxy prims. | |
Usd_PrimFlagsPredicate | UsdTraverseInstanceProxies () |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Convenience method equivalent to calling UsdTraverseInstanceProxies with the UsdPrimDefaultPredicate that is used by default for prim traversals. | |

Predicate that includes all prims. | |
Provides terms for UsdPrim flags that can be combined to form either a conjunction (via &&) or a disjunction (via ||). The result is a predicate functor object that tests those flags on the passed prim. Currently UsdPrim::GetFilteredChildren(), UsdPrim::GetNextFilteredSibling(), UsdPrim::GetFilteredDescendants(), and UsdPrimRange() accept these predicates to filter out unwanted prims.
For example:
For performance, these predicates are implemented by a bitwise test, so arbitrary boolean expressions cannot be represented. The set of boolean expressions that can be represented are conjunctions with possibly negated terms (or disjunctions, by De Morgan's law). Here are some examples of valid expressions:
Here are some examples of invalid expressions:
The following variables provide the clauses that can be combined and negated to produce predicates:

This function is used to allow the prim traversal functions listed under Prim predicate flags to traverse beneath instance prims and return descendants that pass the specified predicate
as instance proxy prims.
For example:
Users may also call Usd_PrimFlagsPredicate::TraverseInstanceProxies to enable traversal beneath instance prims. This function is equivalent to:
However, this function may be more convenient, especially when calling a prim traversal function with a default-constructed tautology predicate.

The default predicate used for prim traversals in methods like UsdPrim::GetChildren, UsdStage::Traverse, and by UsdPrimRange.
This is a conjunction that includes all active, loaded, defined, non-abstract prims, equivalent to:
This represents the prims on a stage that a processor would typically consider present, meaningful, and needful of consideration.
