Method Detail

getMethod

public static Method getMethod(String name,
                               Object target,
                               Map<String,Method> cache)

Locates and returns the first method in the supplied class whose name is equal to the specified name. If a method is located, it will be cached in the supplied cache so that subsequent requests will immediately return the method from the cache rather than re-reflecting.

Returns:

the method with the specified name or null if no method with that name could be found.

getMethod

public static Method getMethod(String name,
                               Object target,
                               Object[] args)

Looks up the method on the specified object that has a signature that matches the supplied arguments array. This is very expensive, so you shouldn't be doing this for something that happens frequently.

Returns:

the best matching method with the specified name that accepts the supplied arguments, or null if no method could be found.
