Constructor Detail

ObjectArraySerializer

public ObjectArraySerializer(byte type,
                             int dataSize,
                             E sample,
                             String dataClassName)

Construct a new ObjectArraySerializer.

Parameters:

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

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

sample - E; sample object (can be zero length array).

dataClassName - String; returned by the dataClassName method

Method Detail

size

public final int size(E[] array)

Description copied from interface: Serializer

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

Parameters:

array - T; Instance of the object

Returns:

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

sizeWithPrefix

public final int sizeWithPrefix(E[] array)

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:

array - T; Instance of the object

Returns:

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

serializeWithPrefix

public final void serializeWithPrefix(E[] array,
                                      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:

array - 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

serialize

public final void serialize(E[] array,
                            byte[] buffer,
                            Pointer pointer,
                            EndianUtil endianUtil)

Description copied from interface: Serializer

Serialize an object of type T; not including the prefix byte(s).

Parameters:

array - 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

deSerialize

public final E[] deSerialize(byte[] buffer,
                             Pointer pointer,
                             EndianUtil endianUtil)

Description copied from interface: Serializer

Deserialize an object of type T. The pointer should be on the first byte of the object; i.e. just after the prefix byte.

Parameters:

buffer - byte[]; the bytes with serialized data that must be reconstructed into a T

pointer - Pointer; position in the buffer where the first byte of the serialized T is located

endianUtil - EndianUtil; selects bigEndian or littleEndian encoding

Returns:

T; a T object constructed from the data in the buffer
