Method Detail

getWeight

public int getWeight()

Get relative size of this object's packed form.

Returns:

relative size of this object's packed form. The special value WEIGHT_UNKNOWN can be returned to indicate the implementation doesn't know, or cannot supply the weight up front.

getFormat

public int getFormat()

Get the storage format type

Returns:

the storage format type, which must be one of PACK_DELTA, PACK_WHOLE, or FORMAT_OTHER.

getDeltaBase

public ObjectId getDeltaBase()

Get identity of the object this delta applies to in order to recover the original object content.

Returns:

identity of the object this delta applies to in order to recover the original object content. This method should only be called if getFormat() returned PACK_DELTA.

wasDeltaAttempted

public boolean wasDeltaAttempted()

Whether the current representation of the object has had delta compression attempted on it.

Returns:

whether the current representation of the object has had delta compression attempted on it.
