Class TreeCache

java.lang.Object
org.dlese.dpc.schemedit.standards.TreeCache
public class TreeCache extends Object
Cashe of AsnStandardsDocuments. Works with a StandardsRegistry instance to support the "getStandardsDocument" call. Maintains a tree map of specified size. When a call to getStandardsDocument is called: - Most recently used list is updated to put that tree first. - if requested tree is not in the tree map, the least recently used tree is destroyed and the requested tree is read (using path obtained from the Registry).
