com.wiredtiger.db.PackInputStream.PackInputStream	(	String	format,
		byte[]	value
	)

Constructor.

Parameters

format	A String that contains the WiredTiger format that defines the layout of this packed value.
value	The raw bytes that back the stream.

com.wiredtiger.db.PackInputStream.PackInputStream	(	String	format,
		byte[]	value,
		int	off,
		int	len
	)

Constructor.

len	Length of the value array that forms the stream.

Member Function Documentation

void com.wiredtiger.db.PackInputStream.getByteArray

(

byte[]

dest

)

throws WiredTigerPackingException

Retrieves a byte array field from the stream.

Parameters

dest	The byte array where the returned value will be stored. The array should be large enough to store the entire data item, if it is not, a truncated value will be returned.

void com.wiredtiger.db.PackInputStream.getByteArray	(	byte[]	dest,
		int	off,
		int	len
	)		throws WiredTigerPackingException

Retrieves a byte array field from the stream.

Parameters

dest	The byte array where the returned value will be stored.
off	Offset into the destination buffer to start copying into.
len	The length should be large enough to store the entire data item, if it is not, a truncated value will be returned.

byte [] com.wiredtiger.db.PackInputStream.getByteArray

(

)

throws WiredTigerPackingException

Retrieves a byte array field from the stream.

Creates a new byte array that is the size of the object being retrieved.
