Method Detail

getObjectCount

public long getObjectCount()
                    throws java.io.IOException

Get the number of objects in this pack.

Specified by:

getObjectCount in class CachedPack

Returns:

the total object count for the pack.

Throws:

java.io.IOException - if the object count cannot be read.

copyAsIs

void copyAsIs(PackOutputStream out,
              WindowCursor wc)
       throws java.io.IOException

Throws:

java.io.IOException

hasObject

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 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 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.

Specified by:

hasObject in class CachedPack

Parameters:

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

rep - representation from the ObjectReuseAsIs instance that originally supplied this CachedPack.

Returns:

true if this pack contains this object.

private Pack[] getPacks()
                 throws java.io.FileNotFoundException

getPackFile

private Pack getPackFile(java.lang.String packName)
                  throws java.io.FileNotFoundException

Throws:
