SubstitutionGroupLeakPreventer

All Implemented Interfaces:

Adapter

public class SubstitutionGroupLeakPreventer
extends Object
implements Adapter

Adapter for preventing memory leaks created by substitution group affiliations.

When an application schema contains an element in the gml:_Feature substitution group a link from gml:_Feature back to the app schema element is created. Since the gml schema (and thus the gml:_Feature) element is a singleton this creates a memory leak. This adapter watches the XSDElementDeclaration.getSubstitutionGroup() of the gml:_Feature element and prevents it from growing in size by making it a unique list of XSDElementDeclaration based on qualified name.
