## org.modeshape.jcr
Class JcrRepository

    java.lang.Object
      org.modeshape.jcr.JcrRepository

All Implemented Interfaces:
  Repository

    @ThreadSafe
    public class JcrRepository

extends Object
implements Repository

Creates JCR `sessions` to an underlying repository (which may be a federated repository).

This JCR repository must be configured with the ability to connect to a repository via a supplied `repository connection factory` and repository source name. An `execution context` must also be supplied to enable working with the underlying ModeShape graph implementation to which this JCR implementation delegates.

If `credentials` are used to login, implementations must also implement one of the following methods:

     public AccessControlContext getAccessControlContext();
     public LoginContext getLoginContext();

Note, `attributes` on credentials are not supported. JCR `SimpleCredentials` are also not supported.

Nested Class Summary
`static class` | `JcrRepository.DefaultOption` The default values for each of the `JcrRepository.Option`.
`protected class` | `JcrRepository.DelegatingConnectionFactory`
`protected class` | `JcrRepository.FederatedRepositoryContext`
`class` | `JcrRepository.Metrics` This component is used internally to expose the metrics of a repository, and should not be used outside of the ModeShape codebase, as it will almost certainly change or be replaced in upcoming releases.
`static class` | `JcrRepository.Option` The available options for the `JcrRepository`.
`static class` | `JcrRepository.QueryLanguage` The set of supported query language string constants.
`static class` | `JcrRepository.RebuildQueryIndexOnStartupOption` The possible values for the `JcrRepository.Option.REBUILD_QUERY_INDEX_ON_STARTUP` option.
`protected class` | `JcrRepository.RepositoryObservationManager`
`protected static class` | `JcrRepository.SourceWorkspacePair`
`static class` | `JcrRepository.VersionHistoryOption` The possible values for the `JcrRepository.Option.VERSION_HISTORY_STRUCTURE` option.

Field Summary
`protected static Map<JcrRepository.Option,String>` | `DEFAULT_OPTIONS` The static unmodifiable map of default options, which are initialized in the static initializer.
