Method Summary

Modifier and Type	Method and Description
boolean	append(int address, byte theByte) Decode one (more) byte.
int	getMaximumWidth() Retrieve the maximum width (in characters) of results that this Decoder can return (all shorter results will be padded to this width with spaces, unless this is the last active Decoder).
String	getResult() Retrieve the current result of this Decoder.
boolean	ignoreForIdenticalOutputCheck() If the result of this Decoder should not be used to compare output lines for suppressing identical lines, this method should return true; otherwise it should return false;

Method Detail

getResult

String getResult()

Retrieve the current result of this Decoder. Decoders that handle multiple byte input may be somewhere within a token. Such Decoders should report a partial result. If no data has been added, the result must be the empty string.

Returns:

String; the current result of this Decoder

getMaximumWidth

int getMaximumWidth()

Retrieve the maximum width (in characters) of results that this Decoder can return (all shorter results will be padded to this width with spaces, unless this is the last active Decoder).

Returns:

int; the maximum width (in characters) of results that this Decoder can return

append

boolean append(int address,
               byte theByte)
        throws IOException

Decode one (more) byte. This method must return true when a line becomes full due to this call, otherwise this method must return false.

Parameters:

address - int; the address that corresponds with the byte

theByte - byte; the byte

Returns:

boolean; true if an output line has been completed by this call; false if at least one more byte can be appended to the local accumulator before the current output line is full

Throws:

IOException - when the output device throws this exception

ignoreForIdenticalOutputCheck

boolean ignoreForIdenticalOutputCheck()

If the result of this Decoder should not be used to compare output lines for suppressing identical lines, this method should return true; otherwise it should return false;

Returns:

boolean; true if the result of this Decoder should be ignored in testing for identical output lines; otherwise false
