getInvokeSpecialHandle

public Object getInvokeSpecialHandle(Method method,
 Object receiver)

handle - the handle

args - arguments for the method call, can be empty but not null

Returns:

the result of the method call

Throws:

Throwable

makeRecordComponents

protected void makeRecordComponents(CompileUnit cu,
 ClassNode cn,
 Class<?> c)

Overrides:

getRecordComponentNames

@Incubating
public List<String> getRecordComponentNames(Class<?> maybeRecord)

Description copied from interface: VMPlugin
