Method Detail

primary

public static Decoder primary(Field field,
                              int value)

This factory method returns a decoder with new values added. This permits a syntax like new Decode.primary(x,y).add(z,a) to be used for multi-level decode.

Parameters:

field - The decode field.

value - the value of the decode field.

Returns:

a decoder is returned.

add

public Decoder add(Field field,
                   long value)

This method returns a decoder with new values added. This permits a syntax like new Decode(x,y,z).add(a,b,c) to be used for multi-level decode.

Parameters:

field - The decode field.

value - the value of the decode field.

Returns:

a decoder

add

public Decoder add(Field field,
                   int value)

This method returns a decoder with new values added. This permits a syntax like new Decode(x,y,z).add(a,b,c) to be used for multi-level decode. This is the same as the other add() method in this class but takes an int value rather than a long.

Parameters:

field - The decode field.

value - the value of the decode field.

Returns:

a decoder
