Method Detail

add

public void add(Method method)
Add a method to a list of methods by name. For a particular class we are keeping track of all the methods with the same name.

find

public Method find(String methodName, Object[] args)

Find a method. Attempts to find the most specific applicable method using the algorithm described in the JLS section 15.12.2 (with the exception that it can't distinguish a primitive type argument from an object type argument, since in reflection primitive type arguments are represented by their object counterparts, so for an argument of type (say) java.lang.Integer, it will not be able to decide between a method that takes int and a method that takes java.lang.Integer as a parameter.

This turns out to be a relatively rare case where this is needed - however, functionality like this is needed.

Parameters: methodName name of method args the actual arguments with which the method is called

Returns: the most specific applicable method, or null if no method is applicable.

Throws: AmbiguousException if there is more than one maximally specific applicable method

get

public List get(String key)
Return a list of methods with the same name.

Parameters: key The name of the method.

Returns: List list of methods
