findMembers

public void findMembers(String name,
 int flags,
 Members list)

Description copied from class: Scope

Finds all members which are declared in this scope or enclosing scopes. This method should be overwritten by subclasses; an invocation of super.findMembers has to be included in order to look for members in enclosing scopes. The flags are a combination of the bit masks defined in Members, they are used to restrict the range of possible members.

Overrides:

findMembers in class Scope

Parameters:

name - simple name of the members to find

flags - combination of masks defined in Members

list - found members are added to this list
