- All Implemented Interfaces:
Repository,RepositoryResolverClient
public class ProxyRepository extends AbstractRepository implements RepositoryResolverClient
Repositoryimplementation that takes aRepositoryResolverinstance and the id of a managed repository, and delegate all calls through to the given repository.The purpose is to allow
Sails to refer to other local repositories using a unique identifier without having to go through an HTTP layer.The implementation is independent of
DelegatingRepositoryso that it is freed from having to provide implementation details in its configuration data. Instead, it only has to provide an unambiguous local identifier to the proxy.- Author:

ProxyRepository
public ProxyRepository()
-
ProxyRepository
public ProxyRepository(String proxiedIdentity)
Creates a repository instance that proxies to a repository of the give ID.- Parameters:
proxiedIdentity- id of the proxied repository
-
ProxyRepository
public ProxyRepository(RepositoryResolver resolver, String proxiedIdentity)
Creates a repository instance that proxies to the given repository.- Parameters:
resolver- manager that the proxied repository is associated withproxiedIdentity- id of the proxied repository

setProxiedIdentity
public final void setProxiedIdentity(String value)
-
getProxiedIdentity
public String getProxiedIdentity()
-
setRepositoryResolver
public final void setRepositoryResolver(RepositoryResolver resolver)
- Specified by:
setRepositoryResolverin interfaceRepositoryResolverClient
-
setDataDir
public void setDataDir(File dataDir)
Description copied from interface:RepositorySet the directory where data and logging for this repository is stored.- Specified by:
setDataDirin interfaceRepository- Parameters:
dataDir- the directory where data for this repository is stored
-
getDataDir
public File getDataDir()
Description copied from interface:RepositoryGet the directory where data and logging for this repository is stored.- Specified by:
getDataDirin interfaceRepository- Returns:
- the directory where data for this repository is stored.
-
isWritable
public boolean isWritable() throws RepositoryExceptionDescription copied from interface:RepositoryChecks whether this repository is writable, i.e. if the data contained in this repository can be changed. The writability of the repository is determined by the writability of the Sail that this repository operates on.- Specified by:
isWritablein interfaceRepository- Throws:
RepositoryException
-
getConnection
public RepositoryConnection getConnection() throws RepositoryException
Description copied from interface:RepositoryOpens a connection to this repository that can be used for querying and updating the contents of the repository. Created connections need to be closed to make sure that any resources they keep hold of are released. The best way to do this is to use a try-with-resources block, as follows:try (RepositoryConnection conn = repository.getConnection()) { // perform operations on the connection }Note that
RepositoryConnectionis not guaranteed to be thread-safe! The recommended pattern for repository access in a multi-threaded application is to share the Repository object between threads, but have each thread create and use its ownRepositoryConnections.- Specified by:
getConnectionin interfaceRepository- Returns:
- A connection that allows operations on this repository.
- Throws:
RepositoryException- If something went wrong during the creation of the Connection.
-
getValueFactory
public ValueFactory getValueFactory()
Description copied from interface:RepositoryGets a ValueFactory for this Repository.- Specified by:
getValueFactoryin interfaceRepository- Returns:
- A repository-specific ValueFactory.
-
initializeInternal
protected void initializeInternal() throws RepositoryException- Specified by:
initializeInternalin classAbstractRepository- Throws:
RepositoryException
-
shutDownInternal
protected void shutDownInternal() throws RepositoryException- Specified by:
