Method Detail

encodeValue

public abstract byte[] encodeValue(ScalarValue value)

decode

public abstract ScalarValue decode(java.io.InputStream in)

encode

public byte[] encode(ScalarValue value)

Template Method to encode the passed object, the actual encoding is done in the encodeValue() method overridden in sub-classes.

Note: The final SBIT is set in this method, not in encodeValue().

Parameters:

value - The ScalarValue object to be encoded

Returns:

Returns an encoded byte array with an added stop bit at the end

isNullable

public boolean isNullable()

Returns:

Returns false
