StaticReferenceCondition

public StaticReferenceCondition(SchemaVariable reference,
                                boolean negation)

the static reference condition checks if a suggested instantiation for a schema variable denotes a static reference. The flag negation allows to reuse this condition for ensuring non static references.

Method Detail

check

public boolean check(SchemaVariable var,
                     SVSubstitute subst,
                     SVInstantiations svInst,
                     Services services)

Description copied from class: VariableConditionAdapter

checks if the condition for a correct instantiation is fulfilled

Specified by:

check in class VariableConditionAdapter

Parameters:

var - the template Variable to be instantiated

svInst - the MatchCondition with the current matching state and in particular the SVInstantiations that are already known to be needed

services - the program information object

Returns:

true iff condition is fulfilled

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
