instance

public static LambdaToMethod instance(Context context)

translate

public <T extends JCTree> T translate(T tree)

Description copied from class: TreeTranslator

Visitor method: Translate a single node.

Overrides:

translate in class TreeTranslator

translateTopLevelClass

public JCTree translateTopLevelClass(Env<AttrContext> env,
                                     JCTree cdef,
                                     TreeMaker make)

visitClassDef

public void visitClassDef(JCTree.JCClassDecl tree)

Visit a class. Maintain the translatedMethodList across nested classes. Append the translatedMethodList to the class after it is translated.

Overrides:

visitClassDef in class TreeTranslator

Parameters:

tree -

visitLambda

public void visitLambda(JCTree.JCLambda tree)

Translate a lambda into a method to be inserted into the class. Then replace the lambda site with an invokedynamic call of to lambda meta-factory, which will use the lambda method.

Overrides:

visitLambda in class TreeTranslator

Parameters:

tree -

visitReference

public void visitReference(JCTree.JCMemberReference tree)

Translate a method reference into an invokedynamic call to the meta-factory.

Overrides:

visitReference in class TreeTranslator

Parameters:

tree -

visitIdent

public void visitIdent(JCTree.JCIdent tree)

Translate identifiers within a lambda to the mapped identifier

Overrides:

visitIdent in class TreeTranslator

Parameters:

tree -

visitVarDef

public void visitVarDef(JCTree.JCVariableDecl tree)

Overrides:

visitVarDef in class TreeTranslator
