de.uka.ilkd.key.symbolic_execution.ExecutionNodeReader.KeYlessLoopInvariant

All Implemented Interfaces:

IExecutionElement, IExecutionLoopInvariant, IExecutionNode<SourceElement>

Enclosing class:

ExecutionNodeReader

public static class ExecutionNodeReader.KeYlessLoopInvariant
extends ExecutionNodeReader.AbstractKeYlessExecutionNode<SourceElement>
implements IExecutionLoopInvariant

An implementation of IExecutionLoopInvariant which is independent from KeY and provides such only children and default attributes.
