Direct Known Subclasses:

ObjectToPack

public class PackedObjectInfo
extends ObjectIdOwnerMap.Entry

Description of an object stored in a pack file, including offset.

When objects are stored in packs Git needs the ObjectId and the offset (starting position of the object data) to perform random-access reads of objects from the pack. This extension of ObjectId includes the offset.

Constructor Detail

PackedObjectInfo

public PackedObjectInfo(AnyObjectId id)

Create a new structure to remember information about an object.

Parameters:

id - the identity of the object the new instance tracks.

Method Detail

getOffset

public long getOffset()

Get offset in pack when object has been already written

Returns:

offset in pack when object has been already written, or 0 if it has not been written yet

setOffset

public void setOffset(long offset)

Set the offset in pack when object has been written to.

Parameters:

offset - offset where written object starts

getCRC

public int getCRC()

Get the 32 bit CRC checksum for the packed data.

Returns:

the 32 bit CRC checksum for the packed data.

setCRC

public void setCRC(int crc)

Record the 32 bit CRC checksum for the packed data.

Parameters:

crc - checksum of all packed data (including object type code, inflated length and delta base reference) as computed by CRC32.

getType

public int getType()

Get the object type.

Returns:

the object type. The default type is OBJ_BAD, which is considered as unknown or invalid type.

Since:

4.9

setType

public void setType(int type)

Record the object type if applicable.

Parameters:

type - the object type.

Since:

4.9
