public long getDeltaCount() throws IOException

Overrides org.eclipse.jgit.internal.storage.pack.CachedPack.getDeltaCount.

Doc from org.eclipse.jgit.internal.storage.pack.CachedPack.getDeltaCount.

Get the number of delta objects stored in this pack.

This is an optional method, not every cached pack storage system knows the precise number of deltas stored within the pack. This number must be smaller than getObjectCount() as deltas are not supposed to span across pack files.

This method must be fast, if the only way to determine delta counts is to scan the pack file's contents one object at a time, implementors should return 0 and avoid the high cost of the scan.

Returns:long

the number of deltas; 0 if the number is not known or there are no deltas.

hasObjectback to summary
public boolean hasObject(ObjectToPack obj, StoredObjectRepresentation rep)

Implements abstract org.eclipse.jgit.internal.storage.pack.CachedPack.hasObject.

Doc from org.eclipse.jgit.internal.storage.pack.CachedPack.hasObject.

Determine if this pack contains the object representation given.

PackWriter uses this method during the finding sources phase to prune away any objects from the leading thin-pack that already appear within this pack and should not be sent twice.

Implementors are strongly encouraged to rely on looking at rep only and using its internal state to decide if this object is within this pack. Implementors should ensure a representation from this cached pack is tested as part of org.eclipse.jgit.internal.storage.pack.ObjectReuseAsIs#selectObjectRepresentation(PackWriter, org.eclipse.jgit.lib.ProgressMonitor, Iterable) , ensuring this method would eventually return true if the object would be included by this cached pack.

Parameters
obj:ObjectToPack

the object being packed. Can be used as an ObjectId.

rep:StoredObjectRepresentation

representation from the org.eclipse.jgit.internal.storage.pack.ObjectReuseAsIs instance that originally supplied this CachedPack.

Returns:boolean

true if this pack contains this object.
