Package org.rcsb.cif.binary.encoding

Class RunLengthEncoding

java.lang.Object

org.rcsb.cif.binary.encoding.RunLengthEncoding

All Implemented Interfaces:

Encoding<IntArray,Int32Array>

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

Represents each integer value in the input as a pair of (value, number of repeats) and stores the result sequentially as Int32Array. Additionally, stores the size of the original array to make decoding easier.

 RunLength {
     kind = "RunLength"
     srcType: int[]
     srcSize: number
 }
 Example
 [1, 1, 1, 2, 3, 3]
 ---RunLength--->
 { srcSize = 6 } [1, 3, 2, 1, 3, 2]

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<IntArray,Int32Array>

Returns:

a Map that contains all encoding information

decode

public IntArray decode(Int32Array 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<IntArray,Int32Array>

Parameters:

data - the container to decode

Returns:

the decoded information

encode

public Int32Array encode(IntArray 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<IntArray,Int32Array>

Parameters:

data - the container to encode

Returns:

the decoded information

toString

public String toString()

Overrides:

toString in class Object
