Class IntegerPackingEncoding

java.lang.Object

org.rcsb.cif.binary.encoding.IntegerPackingEncoding

All Implemented Interfaces:

Encoding<Int32Array,IntArray>

public class IntegerPackingEncoding
extends Object
implements Encoding<Int32Array,IntArray>

Stores a Int32Array using 8- or 16-bit values. Includes the size of the input array for easier decoding. The encoding is more effective when only unsigned values are provided.

 IntegerPacking {
     kind = "IntegerPacking"
     byteCount: number
     srcSize: number
     isUnsigned: boolean
 }
 Example
 [1, 2, -3, 128]
 ---IntegerPacking--->
 { byteCount = 1, srcSize = 4, isUnsigned = false } [1, 2, -3, 127, 1]

Method Details

getMapRepresentation

public Map<String,Object> getMapRepresentation()

Description copied from interface: Encoding

Converts this encoding to its map representation that can be serialized as BinaryCif.

Specified by:

getMapRepresentation in interface Encoding<Int32Array,IntArray>

Returns:

a Map that contains all encoding information

decode

public Int32Array decode(IntArray data)

Description copied from interface: Encoding

Move one step up the encoding deque. One step closer to the original representation of the data.

Specified by:

decode in interface Encoding<Int32Array,IntArray>

Parameters:

data - the container to decode

Returns:

the decoded information

encode

public IntArray encode(Int32Array data)

Description copied from interface: Encoding

Move one step down the encoding deque. One step closer to a ByteArray representation.

Specified by:

encode in interface Encoding<Int32Array,IntArray>

Parameters:

data - the container to encode

Returns:

the decoded information

toString

public String toString()

Overrides:

toString in class Object
