Interface IExecutionMethodReturn

All Superinterfaces:

IExecutionBaseMethodReturn<SourceElement>, IExecutionElement, IExecutionNode<SourceElement>

All Known Implementing Classes:

ExecutionMethodReturn, ExecutionNodeReader.KeYlessMethodReturn

public interface IExecutionMethodReturn
extends IExecutionBaseMethodReturn<SourceElement>

A node in the symbolic execution tree which represents a method return, e.g. return 42.

The default implementation is ExecutionMethodReturn which is instantiated via a SymbolicExecutionTreeBuilder instance.
