Detailed Description

template<class DomainType>
class SdfPredicateProgram< DomainType >

Represents a callable "program", the result of linking an SdfPredicateExpression with an SdfPredicateLibrary via SdfLinkPredicateExpression().

The main public interface this class exposes is the function-call operator(), accepting a single argument of type DomainType, as it is specified to the template. Consider using const Type & as the DomainType for both SdfPredicateProgram and SdfPredicateLibrary if it's important that domain type instances aren't passed by-value.

SdfPredicateProgram SdfLinkPredicateExpression ( SdfPredicateExpression const &  expr, SdfPredicateLibrary< DomainType > const &  lib  )

friend

Link expr with lib and return a callable program that evaluates expr on given objects of the DomainType. If linking expr and lib fails, issue a TF_RUNTIME_ERROR with a message, and return an empty program.
