Method Detail

deserialize

public static java.lang.Integer deserialize(byte[] in)

A static method used to deserialize an Integer from a byte array.

Parameters:

in - The byte array containing the Integer

Returns:

An Integer

deserialize

public static java.lang.Integer deserialize(byte[] in,
                                            int start)

A static method used to deserialize an Integer from a byte array.

Parameters:

in - The byte array containing the Integer

start - the position in the byte[] we will deserialize the int from

Returns:

An Integer

fromBytes

public java.lang.Integer fromBytes(byte[] in)

A method used to deserialize an Integer from a byte array.

Parameters:

in - The byte array containing the Integer

Returns:

An Integer

fromBytes

public java.lang.Integer fromBytes(byte[] in,
                                   int start)

A method used to deserialize an Integer from a byte array.

Parameters:

in - The byte array containing the Integer

start - the position in the byte[] we will deserialize the int from

Returns:

An Integer
