Method Details

getPackNames

String[] getPackNames()

Obtain the array of packfiles in the MultiPackIndex.

The pack ids correspond to positions in this list.

Returns:

array of packnames refered in this multipak index

hasObject

boolean hasObject(AnyObjectId oid)

Does this index contains the object

Parameters:

oid - object id

Returns:

true of the index knows this the object

find

MultiPackIndex.PackOffset find(AnyObjectId objectId)

Obtain the location of the object.

The returned object can be reused by the implementations. Callers must create a #copy() if they want to keep a reference.

Parameters:

objectId - objectId to read.

Returns:

mutable instance with the location or null if not found.

resolve

void resolve(Set<ObjectId> matches,
 AbbreviatedObjectId id,
 int matchLimit)

Find objects matching the prefix abbreviation.

Parameters:

matches - set to add any located ObjectIds to. This is an output parameter.

id - prefix to search for.

matchLimit - maximum number of results to return. At most this many ObjectIds should be added to matches before returning.

getMemorySize

long getMemorySize()

Memory size of this multipack index

Returns:

size of this multipack index in memory, in bytes
