Class XtextBmLinkProvider.UriResourceContainerCache

java.lang.Object

com._1c.g5.v8.dt.bm.xtext.XtextBmLinkProvider.UriResourceContainerCache

Enclosing class:

XtextBmLinkProvider

public abstract static class XtextBmLinkProvider.UriResourceContainerCache
extends Object

Special container for link provider resources. This class provides special behavior for caching elements:

• If cache contains more then getMaxCacheSize() elements - methods removeNonUsingResource() will be called. It deletes all resources with minimal value of XtextBmLinkProvider.UriResourceContainerCache.CacheItem.computeUtility()
• Number of deleting items is defined by removeItemFactor()
