Author: rhauch Date: 2008-11-13 00:31:21 -0500 (Thu, 13 Nov 2008) New Revision: 622 Modified: trunk/dna-graph/src/main/java/org/jboss/dna/graph/connectors/RepositorySourceCapabilities.java trunk/dna-graph/src/test/java/org/jboss/dna/graph/connectors/SimpleRepositorySource.java trunk/dna-graph/src/test/java/org/jboss/dna/graph/connectors/TimeDelayingRepositorySource.java trunk/extensions/dna-connector-federation/src/main/java/org/jboss/dna/connector/federation/FederatedRepositorySource.java trunk/extensions/dna-connector-inmemory/src/main/java/org/jboss/dna/connector/inmemory/InMemoryRepositorySource.java trunk/extensions/dna-connector-jbosscache/src/main/java/org/jboss/dna/connector/jbosscache/JBossCacheSource.java trunk/extensions/dna-connector-svn/src/main/java/org/jboss/dna/connector/svn/SVNRepositorySource.java Log: Changed RepositorySourceCapabilities from an interface to a concrete class, allowing connector to use (or extend) the capabilities so that future additions to this class are automatically inherited by connectors. Also changed all connector implementations and test classes.
