Method Detail

newPackParser

public DfsPackParser newPackParser(InputStream in)
                            throws IOException

Description copied from class: ObjectInserter

Initialize a parser to read from a pack formatted stream.

Specified by:

newPackParser in class ObjectInserter

Parameters:

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

Returns:

the pack parser.

Throws:

IOException - the parser instance, which can be configured and then used to parse objects into the ObjectDatabase.

insert

public ObjectId insert(int type,
                       byte[] data,
                       int off,
                       int len)
                throws IOException

Description copied from class: ObjectInserter

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

Overrides:

insert in class ObjectInserter

Parameters:

type - type code of the object to store.

data - complete content of the object.

off - first position within data.

len - number of bytes to copy from data.

Returns:

the name of the object.

Throws:

IOException - the object could not be stored.

insert

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

Description copied from class: ObjectInserter

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

Specified by:

insert in class ObjectInserter

Parameters:

type - type code of the object to store.

len - number of bytes to copy from in.

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

Returns:

the name of the object.

Throws:

IOException - the object could not be stored, or the source stream could not be read.

flush

public void flush()
           throws IOException

Description copied from class: ObjectInserter

Make all inserted objects visible.

The flush may take some period of time to make the objects available to other threads.

Specified by:

flush in class ObjectInserter

Throws:

IOException - the flush could not be completed; objects inserted thus far are in an indeterminate state.

release

public void release()

Description copied from class: ObjectInserter

Release any resources used by this inserter.

An inserter that has been released can be used again, but may need to be released after the subsequent usage.

Specified by:

release in class ObjectInserter
