getInvokeSpecialHandle

public Object getInvokeSpecialHandle(Method method,
                                     Object receiver)

Description copied from interface: VMPlugin

Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead

Specified by:

getInvokeSpecialHandle in interface VMPlugin

Returns:

null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call

invokeHandle

public Object invokeHandle(Object handle,
                           Object[] args)
                    throws Throwable

Description copied from interface: VMPlugin

Invokes a handle produced by #getInvokeSpecialdHandle

Specified by:

invokeHandle in interface VMPlugin

Parameters:

handle - the handle

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

Returns:

the result of the method call

Throws:

Throwable
