All Implemented Interfaces:

URIConverter

public final class RevisionedURIConverter
extends StorageURIConverter

This URIConverter will be used in order to fetch remote content instead of local content when loading resources.

Constructor Details

RevisionedURIConverter

public RevisionedURIConverter(URIConverter delegate,
 IStorageProviderAccessor storageAccessor,
 IStorageProviderAccessor.DiffSide side)

Instantiates our URI converter given its delegate.

Parameters:

delegate - Our delegate URI converter.

storageAccessor - The accessor that will provide synchronization information for the loaded files.

side - The side we are currently resolving.

Method Details

prefetchStream

public boolean prefetchStream(URI uri,
 Map<?,?> options)
                       throws IOException

Prefetches the input stream for the given URI if any. Note that the stream will be left opened and cached by this URIConverter, only to be closed when the associated "load resource" is called.

See comments on prefetchedStreams. This is used to avoid loading a single URI more than once.

Parameters:

uri - see createInputStream(URI, Map)

options - see createInputStream(URI, Map)

Returns:

true if there is an input stream accessible for the given uri, false otherwise.

Throws:

IOException - if an IO problem occurs.

createInputStream

public InputStream createInputStream(URI uri,
 Map<?,?> options)
                              throws IOException

Specified by:

createInputStream in interface URIConverter

Overrides:

createInputStream in class StorageURIConverter

Throws:

IOException

• StorageURIConverter.createInputStream(org.eclipse.emf.common.util.URI, java.util.Map)

exists

public boolean exists(URI uri,
 Map<?,?> options)

Specified by:

exists in interface URIConverter

Overrides:

exists in class DelegatingURIConverter
