type describing theSegment
subclass to be "enriched" with breaking functionality.

public class BreakerSegmentDecorator<DECORATEE extends Segment>
extends AbstractTransmissionDecorator<DECORATEE>
implements DecoratorSegment<DECORATEE>, org.refcodes.mixin.Resetable
The
BreakerSegmentDecorator
is a DecoratorSegment
build to
test error detection and error correction Transmission
implementations such as the CrcSegmentDecorator
or the
StopAndWaitSegmentDecorator
. To achieve this, the
BreakerSegmentDecorator
can be configured to "break" deserialization
for a given number of times by intercepting into the according
Transmission
's methods and throwing a
TransmissionSequenceException
.- See Also:

BreakerSegmentDecorator
Constructs aBreakerSegmentDecorator
instance with the given decoratee breaking deserialization of the decorated segments by the given number of times.fter the total number of breaking the decoratee has been reached, the decorator behaves transparent (it just delegates without breaking the decoratee any more). This is good to see if a retry mechanism works when using some kind of error correction segment.- Parameters:
aDecoratee
- The decoratee to be contained by this facade.aBreakNumber
- The number of times to break deserialization.
-

Method Details
-
fromTransmission
(Re-)initializes this instance with the the givenSequence
data.- Specified by:
fromTransmission
in interfaceSegment
- Parameters:
aSequence
- TheSequence
data from which to (re-)initialize this instance.aOffset
- The offset where to start processing the providedSequence
.- Returns:
- The index after the last offset into the given
Sequence
processed by this method. - Throws:
TransmissionException
- thrown in case a givenSequence
cannot be processed.
-
receiveFrom
(Re-)initializes this instance by receiving the accordingSequence
from the givenInputStream
. Implementations providing error correction methods use the provided feedbackOutputStream
to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the received data.- Specified by:
receiveFrom
in interfaceSegment
- Parameters:
aInputStream
- TheInputStream
from which to read the instance's (re-)initializationSequence
from.aReturnStream
- AnOutputStream
being the return channel to handle "stop-and-wait ARQ" or the like in case of a bidirectional connection. Can be null in case we have a unidirectional connection.- Throws:
IOException
- thrown in case reading data from theInputStream
caused problems.TransmissionException
- thrown in case a given transmission cannot be processed.
-
toSchema
- Specified by:
toSchema
in interfaceorg.refcodes.mixin.Schemable
- Specified by:

in interfaceTransmission

reset
public void reset()Resets any dynamic data (e.g. values such as payloads or checksums) and must not(!) reset any configurations or settings required to produce the dynamic data (e.g. theTransmissionMetrics
).- Specified by:
