Inner Class :public static class AmbiguousException extends Exception

Field Summary
protected  MapmethodByNameMap
     Keep track of all methods with the same name.


Method Summary
public  voidadd(Method method)
     Add a method to a list of methods by name.
public  Methodfind(String methodName, Object[] args)
    

Find a method.

public  Listget(String key)
     Return a list of methods with the same name.
Parameters:
  key - The method name.

Field Detail
methodByNameMap
protected Map methodByNameMap(Code)
Keep track of all methods with the same name.





Method Detail
add
public void add(Method method)(Code)
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.
Parameters:
  method - the method.



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

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
Parameters:
  args - the actual arguments with which the method is called the most specific applicable method, or null if no method isapplicable.
throws:
  AmbiguousException - if there is more than one maximally specificapplicable method



get
public List get(String key)(Code)
Return a list of methods with the same name.
Parameters:
  key - The method name. List list of methods
