public class NewInstanceMetaMethod
extends NewMetaMethod

A MetaMethod implementation where the underlying method is really a static helper method on some class but it appears to be an instance method on a class. This implementation is used to add new methods to the JDK writing them as normal static methods with the first parameter being the class on which the method is added.

Constructor Details

NewInstanceMetaMethod

public NewInstanceMetaMethod(CachedMethod method)

Constructs a new NewInstanceMetaMethod.

Parameters:

method - the cached static helper method

Method Details

isStatic

public boolean isStatic()

Indicates this method is not static (it appears as an instance method).

Returns:

false, as this wraps a static method to appear as an instance method

getModifiers

public int getModifiers()

Returns the modifiers for this method (PUBLIC without STATIC).

Specified by:

getModifiers in interface MetaMember

Overrides:

getModifiers in class ReflectionMetaMethod

Returns:

PUBLIC modifier only

invoke

public Object invoke(Object object,
 Object[] arguments)

Invokes the underlying static method with the object as the first argument. This adapts instance method calls to the underlying static method signature.

Overrides:

invoke in class ReflectionMetaMethod

Parameters:

object - the object to invoke the method on (passed as first argument to static method)

arguments - the method arguments

Returns:

the method return value
