Class IntervalQuantizationEncoding

java.lang.Object

org.rcsb.cif.binary.encoding.IntervalQuantizationEncoding

All Implemented Interfaces:

Encoding<FloatArray,Int32Array>

public class IntervalQuantizationEncoding
extends Object
implements Encoding<FloatArray,Int32Array>

Converts an array of floating point numbers to a Int32Array where the values are quantized within a given interval into specified number of discrete steps. Values lower than the minimum value or greater than the maximum are represented by the respective boundary values.

 FixedPoint {
     kind = "IntervalQuantization"
     min: number,
     max: number,
     numSteps: number,
     srcType: Float32 | Float64
 }
 Example
 [0.5, 1, 1.5, 2, 3, 1.345 ]
 ---IntervalQuantization--->
 { min = 1, max = 2, numSteps = 3 } [0, 0, 1, 2, 2, 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<FloatArray,Int32Array>

Returns:

a Map that contains all encoding information

decode

public FloatArray 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<FloatArray,Int32Array>

Parameters:

data - the container to decode

Returns:

the decoded information

encode

public Int32Array encode(FloatArray 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<FloatArray,Int32Array>

Parameters:

data - the container to encode

Returns:

the decoded information

toString

public String toString()

Overrides:

toString in class Object
