All Methods Instance Methods Concrete Methods Modifier and Type Method Description
getDeltaCount()Get the number of delta objects stored in this pack.
getObjectCount()Get the number of objects in this pack.
getPackDescription()Get the description of the pack.
hasObject(ObjectToPack obj, StoredObjectRepresentation rep)Determine if this pack contains the object representation given.
public DfsPackFile getPackFile()
- the pack passed to the constructor
public DfsPackDescription getPackDescription()Get the description of the pack.
- the description of the pack.
public long getObjectCount() throws IOExceptionGet the number of objects in this pack.
public long getDeltaCount() throws IOExceptionGet 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
CachedPack.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.
public boolean hasObject(ObjectToPack obj, StoredObjectRepresentation rep)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
reponly 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
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.
