Constructor Summary

Constructors

Constructor	Description
SingleConstraint1(String exprId, PredicateInformation predicateInformation)	This constructor generates a constraint that cannot be evaluated as it lacks the actual predicate The AlphaNode referring this can be shared, as the exprId is provided Currently it's used only with the Alpha Network Compiler, since the code instantiating the actual constraint will be inlined inside the compiled Alpha Network itself.

SingleConstraint1

This constructor generates a constraint that cannot be evaluated as it lacks the actual predicate The AlphaNode referring this can be shared, as the exprId is provided Currently it's used only with the Alpha Network Compiler, since the code instantiating the actual constraint will be inlined inside the compiled Alpha Network itself.
