Detailed Description

Conjunction of prim flag predicate terms.

Usually clients will implicitly create conjunctions by &&-ing together flag predicate terms. For example:

// Get all loaded model children.
prim.GetFilteredChildren(UsdPrimIsModel && UsdPrimIsLoaded)

See primFlags.h for more details.

Constructor & Destructor Documentation

Usd_PrimFlagsConjunction::Usd_PrimFlagsConjunction ( )

inline

Default constructed conjunction is a tautology.

Definition at line 301 of file primFlags.h.

Usd_PrimFlagsConjunction::Usd_PrimFlagsConjunction ( Usd_Term  term )

inlineexplicit

Construct with a term.

Definition at line 304 of file primFlags.h.

Member Function Documentation

USD_API class Usd_PrimFlagsDisjunction Usd_PrimFlagsConjunction::operator!

(

)

const

Negate this conjunction, producing a disjunction by De Morgan's law. For instance:

!(UsdPrimIsLoaded && UsdPrimIsModel)

Will negate the conjunction in parens to produce a disjunction equivalent to:

(!UsdPrimIsLoaded || !UsdPrimIsModel)

Every expression may be formulated as either a disjunction or a conjuction, but allowing both affords increased expressiveness.

Usd_PrimFlagsConjunction& Usd_PrimFlagsConjunction::operator&= ( Usd_Term  term )

inline

Add an additional term to this conjunction.

Definition at line 309 of file primFlags.h.
