Class ToBytesViaStringDeserialiser<T>

java.lang.Object

uk.gov.gchq.gaffer.serialisation.ToBytesViaStringDeserialiser<T>

All Implemented Interfaces:

Serializable, Serialiser<T,byte[]>, ToBytesSerialiser<T>

Direct Known Subclasses:

StringSerialiser, TreeSetStringSerialiser

public abstract class ToBytesViaStringDeserialiser<T>
extends Object
implements ToBytesSerialiser<T>

Abstract serialiser that deserialises the given byte[] via an interim String object. The concrete implementation of this class may use the string in the constructor of the final return type.
example :

   @Override
 public Date deserialiseString(final String value) {
 return new Date(Long.parseLong(value));
 }

deserialise

@Deprecated
public final T deserialise(byte[] bytes)
                    throws SerialisationException

Deprecated.

Deserialise an array of bytes into the original object.

Specified by:

deserialise in interface Serialiser<T,byte[]>

Specified by:

deserialise in interface ToBytesSerialiser<T>

Parameters:

bytes - the bytes to deserialise

Returns:

T the deserialised object

Throws:

SerialisationException - if the object fails to deserialise

Note that this implementation is less efficient than using deserialise with an offset and a length, but may still be used if necessary. It has been marked deprecated but will not be removed as it is needed in the Serialiser interface.

deserialise

public final T deserialise(byte[] allBytes,
                           int offset,
                           int length)
                    throws SerialisationException

Specified by:

deserialise in interface ToBytesSerialiser<T>

Parameters:

allBytes - The bytes to be decoded into characters

offset - The index of the first byte to decode

length - The number of bytes to decode

Returns:

T the deserialised object

Throws:

SerialisationException - issues during deserialisation

serialise

public byte[] serialise(T object)
                 throws SerialisationException

Description copied from interface: ToBytesSerialiser

Serialise some object and returns the raw bytes of the serialised form.

Specified by:

serialise in interface Serialiser<T,byte[]>

Specified by:

serialise in interface ToBytesSerialiser<T>

Parameters:

object - the object to be serialised

Returns:

byte[] the serialised bytes

Throws:
