Class ReturnExpressionMutationExtractionTranslator

java.lang.Object

com.sun.tools.javac.tree.JCTree.Visitor

com.sun.tools.javac.tree.TreeTranslator

io.ghostwriter.openjdk.v7.ast.translator.ReturnExpressionMutationExtractionTranslator

All Implemented Interfaces:

Translator<Method>

public class ReturnExpressionMutationExtractionTranslator
extends com.sun.tools.javac.tree.TreeTranslator
implements Translator<Method>

Return statements might contain value assignments or other expression that can trigger value change events. In order to support this language construct, the code needs to be modified in such a way that the return statements only contain the result of the value change expression and not the value change expression itself. Depends on WrapInBlockTranslator execution, since it assumes that 'return' statements will only occur in blocks and not inside other language constructs, such as an 'if'.
