                              Object... parameters)

Invoke a method on the wrapped class (not the wrapped object) in a static way.

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper. For performance reasons, the Method instances are cached and the cache key is this methodID (rather than a long String comprising methodName and parameterTypes).

methodName - method name as passed to Class.getMethod(String, Class...).

parameterTypes - parameter types as passed to Class.getMethod(String, Class...).

parameters - parameters as passed to Method.invoke(Object, Object...).

Returns:

the result of the method invocation as returned from Method.invoke(Object, Object...).

invoke

protected Object invoke(int methodID,
                        String methodName)

Invoke a method on the wrapped object. This is a convenience method delegating to invoke(int, String, Class[], Object...).

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper.

methodName - method name.

Returns:

the result of the method invocation.

invoke

protected Object invoke(int methodID,
                        String methodName,
                        Class<?> parameterType,
                        Object parameter)

Invoke a method on the wrapped object. This is a convenience method delegating to invoke(int, String, Class[], Object...).

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper.

methodName - method name.

parameterType - single parameter type.

parameter - single parameter.

Returns:

the result of the method invocation.

invoke

protected Object invoke(int methodID,
                        String methodName,
                        Class<?> parameterType1,
                        Class<?> parameterType2,
                        Object... parameters)

Invoke a method on the wrapped object. This is a convenience method delegating to invoke(int, String, Class[], Object...).

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper.

methodName - method name.

parameterType1 - first parameter type.

parameterType2 - second parameter type.

parameters - two parameters (corresponding to the two parameter types).

Returns:

the result of the method invocation.

invoke

protected Object invoke(int methodID,
                        String methodName,
                        Class<?> parameterType1,
                        Class<?> parameterType2,
                        Class<?> parameterType3,
                        Object... parameters)

Invoke a method on the wrapped object. This is a convenience method delegating to invoke(int, String, Class[], Object...).

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper.

methodName - method name.

parameterType1 - first parameter type.

parameterType2 - second parameter type.

parameterType3 - third parameter type.

parameters - three parameters (corresponding to the three parameter types).

Returns:

the result of the method invocation.

invoke

protected Object invoke(int methodID,
                        String methodName,
                        Class<?>[] parameterTypes,
                        Object... parameters)

Invoke a method on the wrapped object.

Parameters:

methodID - identifier that must be unique within the subclass of ReflectionWrapper. For performance reasons, the Method instances are cached and the cache key is this methodID (rather than a long String comprising methodName and parameterTypes).

methodName - method name as passed to Class.getMethod(String, Class...).

parameterTypes - parameter types as passed to Class.getMethod(String, Class...).

parameters - parameters as passed to Method.invoke(Object, Object...).

Returns:

the result of the method invocation as returned from Method.invoke(Object, Object...).
