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 Detail
-
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
- seecreateInputStream(URI, Map)
options
- seecreateInputStream(URI, Map)
- Returns:
true
if there is an input stream accessible for the given uri,false
otherwise.- Throws:
IOException
- if an IO problem occurs.- See Also:
