Class SubFormulaCondition

java.lang.Object

de.uka.ilkd.key.rule.VariableConditionAdapter

de.uka.ilkd.key.rule.conditions.SubFormulaCondition

All Implemented Interfaces:

VariableCondition

public class SubFormulaCondition
extends VariableConditionAdapter

This variable condition checks if an instantiation for a formula has sub formulas which are formulas. It returns false for an arity equal to zero or no sub formulas. This is needed to simplify distinguishing between different well-definedness operators in taclets, since the difference exists only for formulas.
