Description copied from interface: Serializer

Serializes the content of the given value into the given DataOutput2.

Specified by:

serialize in interface Serializer<java.lang.Long>

Overrides:

serialize in class SerializerLong

Parameters:

out - DataOutput2 to save object into

value - Object to serialize

Throws:

java.io.IOException - in case of an I/O error

deserialize

public java.lang.Long deserialize(DataInput2 in,
                                  int available)
                           throws java.io.IOException

Description copied from interface: Serializer

Deserializes and returns the content of the given DataInput2.

Specified by:

fixedSize

public int fixedSize()

Description copied from interface: Serializer

Returns the fixed size of the serialized form in bytes or -1 if the size is not fixed (e.g. for Strings).

Some optimizations can be applied to serializers with a fixed size.

Specified by:

fixedSize in interface Serializer<java.lang.Long>

Overrides:

fixedSize in class SerializerEightByte<java.lang.Long>

Returns:

the fixed size of the serialized form in bytes or -1 if the size is not fixed
