getMethodType back to summary

getMethodType	back to summary
public MethodType getMethodType() Implements java.lang.invoke.MethodHandleInfo.getMethodType. Doc from java.lang.invoke.MethodHandleInfo.getMethodType. Returns the nominal type of the cracked symbolic reference, expressed as a method type. If the reference is to a constructor, the return type will be `void`. If it is to a non-static method, the method type will not mention the `this` parameter. If it is to a field and the requested access is to read the field, the method type will have no parameters and return the field type. If it is to a field and the requested access is to write the field, the method type will have one parameter of the field type and return `void`. Note that original direct method handle may include a leading `this` parameter, or (in the case of a constructor) will replace the `void` return type with the constructed class. The nominal type does not include any `this` parameter, and (in the case of a constructor) will return `void`. Annotations @Override
