getInvokeSpecialHandle
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 interfaceVMPlugin
- Returns:
- null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
-
invokeHandle
Description copied from interface:VMPlugin
Invokes a handle produced by #getInvokeSpecialdHandle- Specified by:
invokeHandle
in interfaceVMPlugin
- Parameters:
handle
- the handleargs
- arguments for the method call, can be empty but not null- Returns:
- the result of the method call
- Throws:
