Author: rhauch Date: 2008-07-03 14:23:41 -0400 (Thu, 03 Jul 2008) New Revision: 340 Added: trunk/dna-spi/src/main/java/org/jboss/dna/spi/graph/commands/executor/ trunk/dna-spi/src/main/java/org/jboss/dna/spi/graph/commands/executor/AbstractCommandExecutor.java trunk/dna-spi/src/main/java/org/jboss/dna/spi/graph/commands/executor/CommandExecutor.java trunk/dna-spi/src/test/java/org/jboss/dna/spi/graph/commands/ trunk/dna-spi/src/test/java/org/jboss/dna/spi/graph/commands/executor/ trunk/dna-spi/src/test/java/org/jboss/dna/spi/graph/commands/executor/AbstractCommandExecutorTest.java Modified: trunk/connectors/dna-connector-inmemory/src/main/java/org/jboss/dna/connector/inmemory/InMemoryRepository.java trunk/connectors/dna-connector-inmemory/src/main/java/org/jboss/dna/connector/inmemory/InMemoryRepositoryConnection.java trunk/connectors/dna-connector-jbosscache/pom.xml trunk/connectors/dna-connector-jbosscache/src/main/java/org/jboss/dna/connector/jbosscache/JBossCacheConnection.java Log: DNA-171 - Create basic command executor http://jira.jboss.com/jira/browse/DNA-171 Created CommandExecutor interface and an AbstractCommandExecutor abstract (but complete) implementation. The unit tests verify that the 'execute(GraphCommand)' method properly delegates to the other more specific 'execute(...)' methods, and that the 'execute(CompositeCommand)' method properly iterates over the nested commands.
