Package org.modeshape.graph.connector.path Description

The PathRepository class and its supporting classes provide a default read-only implementation of the connector classes for connectors that only support path-based access to a standard representation of a node. Connectors to systems that provide a unique identifier for each node would generally be better implemented using the map repository implementation instead. To implement a connector based on this framework, one must create an implementation of the repository source, an implementation of the repository itself, and an implementation of the workspace.

The repository source implementation contains properties for the repository configuration and caching policies. A key method in the PathRepositorySource implementation if the RepositorySource.getConnection() method, which should generally be implemented using the default connection implementation.

 if (repository == null) {
  repository = new JdbcMetadataRepository(this);
 }
 return new MapRepositoryConnection(this, repository); 
 

The repository implementation is only required to provide an implementation of the PathRepository.initialize() method to initialize the repository with a default workspace implementation for the connector and an implementation of PathWorkspace. All constructors for the repository must call PathRepository.initialize() after the constructor has completed its initialization, as demonstrated below:

 public JdbcMetadataRepository( JdbcMetadataSource source ) {
   initialize();
 }
