Constructor Details

ArrayOrMatrixSerializer

ArrayOrMatrixSerializer(byte type,
 int elementSize,
 String dataClassName,
 int numberOfDimensions)

Construct a new ArrayOrMatrixSerializere.

Parameters:

type - byte; the field type (returned by the fieldType method)

elementSize - int; the number of bytes needed to encode one additional array, or matrix element

dataClassName - String; returned by the dataClassName method

numberOfDimensions - int; should be 1 for array serializer and 2 for matrix serializer

Method Details

getElementSize

public final int getElementSize()

Return the number of bytes needed to encode one additional element.

Returns:

int; the number of bytes needed to encode one additional element

getNumberOfDimensions

public final int getNumberOfDimensions()

Return the number of dimensions of the stored data.

Returns:

int; 1 for array, 2 for matrix

serializeElement

public abstract void serializeElement(E object,
 byte[] buffer,
 int offset,
 EndianUtil endianUtil)

Serializer for one array or matrix element (without type prefix) must be implemented in implementing sub classes.

Parameters:

object - E; the object to serialize

buffer - byte[]; the byte buffer for the serialized object

offset - int; index in byte buffer where first serialized byte must be stored

endianUtil - EndianUtil; selects bigEndian or littleEndian encoding

deSerializeElement

public abstract E deSerializeElement(byte[] buffer,
 int offset,
 EndianUtil endianUtil)

Deserializer for one array or matrix element (without type prefix) must be implemented in implementing sub classes.

Parameters:

buffer - byte[]; the byte buffer from which the object is to be deserialized

offset - int; index in byte buffer where first byte of the object is stored

endianUtil - EndianUtil; selects bigEndian or littleEndian encoding

Returns:

E; the deserialized object
