Class FSComponentExtRepositoryDB<FSCRC extends FSCRDBComponent>

java.lang.Object

com.zfabrik.components.provider.util.FSComponentExtRepositoryDB<FSCRC>

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

FSComponentRepositoryDB

public class FSComponentExtRepositoryDB<FSCRC extends FSCRDBComponent>
extends java.lang.Object
implements java.io.Serializable

A utility for component repository implementers. This helps implementing the index of components provided and query functionality (see IComponentsRepository.findComponents(X) as well as a simple query cache. This class is not thread safe.

Find locally in this DB (see also IComponentsRepository.findComponents(X)

Parameters:

propertyExpression -

Throws:

java.io.IOException

getRevision

public long getRevision(java.lang.String cn)

Gets rev of local component

Parameters:
