Interface RepositoryContext

All Known Implementing Classes:

SimpleRepositoryContext

@ThreadSafe
public interface RepositoryContext

The context for a repository. This interface need not be implemented by a RepositorySource, as it is normally provided to the source when initialized.

Method Summary

Subgraph	getConfiguration(int depth) Get a snapshot of the current configuration for the RepositorySource.
ExecutionContext	getExecutionContext() Get the execution context, which can be used to create other contexts with specific JAAS security contexts.
Observer	getObserver() Get the observer that the connector may use to publish changes.
RepositoryConnectionFactory	getRepositoryConnectionFactory() Get the factory for connections to other sources.

Method Detail

getExecutionContext

ExecutionContext getExecutionContext()

Get the execution context, which can be used to create other contexts with specific JAAS security contexts.

Returns:

the execution context; never null

getRepositoryConnectionFactory

RepositoryConnectionFactory getRepositoryConnectionFactory()

Get the factory for connections to other sources.

Returns:

the connection factory

getObserver

Observer getObserver()

Get the observer that the connector may use to publish changes.

Returns:

the observer, or null if the are no listeners and publishing is not required/requested

getConfiguration

Subgraph getConfiguration(int depth)

Get a snapshot of the current configuration for the RepositorySource. The root of the subgraph will be the node in the configuration that represents the RepositorySource.

Parameters:

depth - the max depth of the configuration subgraph

Returns:

the configuration snapshot as a subgraph, or null if there is no configuration
