Method Detail

encode

public void encode(java.lang.Integer x,
                   java.io.DataOutput dataOut)
            throws java.io.IOException

Description copied from interface: Codec

Write the payload of the object to the DataOutput stream.

Specified by:

encode in interface Codec<java.lang.Integer>

Throws:

java.io.IOException

decode

public java.lang.Integer decode(java.io.DataInput dataIn)
                         throws java.io.IOException

Description copied from interface: Codec

Read the payload of the object from the DataInput stream.

Specified by:

decode in interface Codec<java.lang.Integer>

Returns:

unmarshalled object

Throws:

java.io.IOException

getFixedSize

public int getFixedSize()

Specified by:

getFixedSize in interface Codec<java.lang.Integer>

Returns:

-1 if the object do not always marshall to a fixed size, otherwise return that fixed size.

deepCopy

public java.lang.Integer deepCopy(java.lang.Integer source)

Specified by:

deepCopy in interface Codec<java.lang.Integer>

Returns:

the source object since integers are immutable.

isDeepCopySupported

public boolean isDeepCopySupported()

Specified by:

isDeepCopySupported in interface Codec<java.lang.Integer>

Returns:

true if the Codec.deepCopy(Object) operations is supported.

isEstimatedSizeSupported

public boolean isEstimatedSizeSupported()

Specified by:

isEstimatedSizeSupported in interface Codec<java.lang.Integer>

Returns:

true if the Codec.estimatedSize(Object) operation is supported.

estimatedSize

public int estimatedSize(java.lang.Integer x)

Specified by:

estimatedSize in interface Codec<java.lang.Integer>

Returns:

the estimated marshaled size of the object.
