Constructor Details

BasicPrimitiveArrayOrMatrixSerializer

public BasicPrimitiveArrayOrMatrixSerializer(byte type,
 int elementSize,
 String dataClassName,
 int numberOfDimensions)

Construct a new BasicPrimitiveArrayOrMatrixSerializer.

Parameters:

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

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

dataClassName - String; returned by the dataClassName method

numberOfDimensions - int; number of dimensions (1 for array, 2 for matrix)

Method Details

sizeWithPrefix

public final int sizeWithPrefix(T object)
                         throws SerializationException

Description copied from interface: Serializer

Compute the number of bytes needed to serialize an object of type T (including the byte(s) that indicate that an object of type T is next in the data stream).

Parameters:

object - T; Instance of the object

Returns:

int; the number of bytes needed to serialize an object of type T

Throws:

SerializationException - when the object cannot be serialized

serializeWithPrefix

public final void serializeWithPrefix(T object,
 byte[] buffer,
 Pointer pointer,
 EndianUtil endianUtil)
                               throws SerializationException

Description copied from interface: Serializer

Serialize an object of type T including the prefix byte(s).

Parameters:

object - T; the object to serialize

buffer - byte[]; buffer for the serialized T

pointer - Pointer; position in buffer where the first byte of the serialized T will be stored

endianUtil - EndianUtil; selects bigEndian or littleEndian encoding

Throws:

SerializationException - when a matrix has size zero or is jagged

getElementSize

public final int getElementSize()

Retrieve the number of bytes needed to encode one additional array element.

Returns:

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

getNumberOfDimensions

public final int getNumberOfDimensions()

Description copied from interface: Serializer

Return the number of dimensions of the stored data.

Returns:

int; 0 for plain data, 1 for array, 2 for matrix
