Member Function Documentation

static byte [] openlsd.common.LSDByteToByte.newbytefromoffset	(	byte[]	from,
		int	rank,
		int	blocksize
	)			[static]

Create a sub array of byte from the array 'from', starting at position (rank-1)*blocksize up to rank*blocksize-1.

Parameters:

	from
	rank
	blocksize

Returns:

the sub byte from offset or null if error

static byte [] openlsd.common.LSDByteToByte.newbytefromprevious	(	byte[]	previous,
		byte[]	addbytes
	)			[static]

Add to previous the array of byte addbytes at the end and return the new array.

Parameters:

	previous
	addbytes

Returns:

the array being the concatenation of both byte arrays or null if error

static boolean openlsd.common.LSDByteToByte.copysubsettooffset	(	byte[]	from,
		int	offsetsrc,
		int	length,
		byte[]	tooffset,
		int	offsetdst
	)			[static]

Copy a sub array of byte to an offset position.

Parameters:

	from	array of byte source
	offsetsrc	position (offset) in source
	length	length of bytes to copy
	tooffset	array of byte destination
	offsetdst	position (offset) in destination

Returns:

True if OK, False if KO.

static boolean openlsd.common.LSDByteToByte.bytesEqualBytes	(	byte[]	from,
		byte[]	to
	)			[static]

Check if array of bytes are equals

Parameters:

	from
	to

Returns:

True if equals, False if not

static byte [] openlsd.common.LSDByteToByte.bytesFromFile

(

String

filename

)

[static]

Load a file from filename in a array of byte (function no more used)

Parameters:

filename

Returns:

the array of byte from the file, or null

Deprecated:

This function is no more used
