private ObjectId insert(int type, byte[] data, int off, int len, boolean createDuplicate) throws IOException

Insert a loose object into the database. If createDuplicate is true, write the loose object even if we already have it in the loose or packed ODB.

Parameters
type:int

object type

data:byte[]

object data

off:int

first position within @{code data}

len:int

length number of bytes to copy

createDuplicate:boolean

whether to insert a duplicate if an object with this id already exists

Returns:ObjectId

ObjectId the name of the object

public ObjectId insert(int type, long len, InputStream is) throws IOException

Implements abstract org.eclipse.jgit.lib.ObjectInserter.insert.

Doc from org.eclipse.jgit.lib.ObjectInserter.insert.

Insert a single object into the store, returning its unique name.

Parameters
type:int

type code of the object to store.

len:long

number of bytes to copy from in.

is:InputStream

stream providing the object content. The caller is responsible for closing the stream.

Returns:ObjectId

the name of the object.

pack-priv ObjectId insert(int type, long len, InputStream is, boolean createDuplicate) throws IOException

Insert a loose object into the database. If createDuplicate is true, write the loose object even if we already have it in the loose or packed ODB.

Parameters
type:int

object type

len:long

number of bytes to copy

is:InputStream

input stream

createDuplicate:boolean

whether to insert a duplicate if an object with this id already exists

Returns:ObjectId

ObjectId the name of the object

public PackParser newPackParser(InputStream in) throws IOException

Implements abstract org.eclipse.jgit.lib.ObjectInserter.newPackParser.

Doc from org.eclipse.jgit.lib.ObjectInserter.newPackParser.

Initialize a parser to read from a pack formatted stream.

Parameters
in:InputStream

the input stream. The stream is not closed by the parser, and must instead be closed by the caller once parsing is complete.

Returns:PackParser

the pack parser.

Annotations
@Override
Exceptions
IOException:
the parser instance, which can be configured and then used to parse objects into the ObjectDatabase.
newReaderback to summary
public ObjectReader newReader()

Implements abstract org.eclipse.jgit.lib.ObjectInserter.newReader.

Doc from org.eclipse.jgit.lib.ObjectInserter.newReader.

Open a reader for objects that may have been written by this inserter.

The returned reader allows the calling thread to read back recently inserted objects without first calling flush() to make them visible to the repository. The returned reader should only be used from the same thread as the inserter. Objects written by this inserter may not be visible to this.newReader().newReader().

The returned reader should return this inserter instance from ObjectReader#getCreatedFromInserter().

Behavior is undefined if an insert method is called on the inserter in the middle of reading from an ObjectStream opened from this reader. For example, reading the remainder of the object may fail, or newly written data may even be corrupted. Interleaving whole object reads (including streaming reads) with inserts is fine, just not interleaving streaming partial object reads with inserts.

Returns:ObjectReader

reader for any object, including an object recently inserted by this inserter since the last flush.
