Method Detail
-
getLength
public int getLength()
Determines the overall length of thisTransmission
. In case of nestedTransmission
instances, all length values from all sub-segments are accumulated to the result as well.- Specified by:
getLength
in interfaceorg.refcodes.mixin.LengthAccessor
- Specified by:
getLength
in interfaceTransmission
- Returns:
- The (overall) length of the
Transmission
(including any sub-segments).
-
toSequence
public Sequence toSequence()
Provides theSequence
representation of thisTransmission
. In case of nestedTransmission
instances, allSequence
representations from all sub-segments are accumulated to the result as well. Caution, the Transmission (or its nestedTransmission
instances) may be backed by the returnedSequence
.- Specified by:
toSequence
in interfaceTransmission
- Returns:
- The according instance's
Sequence
.
-
transmitTo
public void transmitTo(OutputStream aOutputStream, InputStream aReturnStream) throws IOException
Transmits theSequence
representing the implementing type's instance to the givenOutputStream
. Implementations providing error correction methods use the provided feedbackInputStream
to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the transmitted data.- Specified by:
transmitTo
in interfaceTransmission
- Parameters:
aOutputStream
- TheOutputStream
where to write this instance'sSequence
to.aReturnStream
- AnInputStream
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 writing data to theOutputStream
caused problems.
-
toSchema
public Schema toSchema()
Retrieves theSchema
representing theTransmission
. Retrieving aSchema
is useful when analyzing and debugging data structures such as aAllocSectionDecoratorSegment
instance to help document, learn and verify on the structure (as well as the content) of that veryAllocSectionDecoratorSegment
.- Specified by:
toSchema
in interfaceTransmission
- Returns:
- The
Schema
representation of the implementing type for debugging and verification (or documentation) purposes.
-
toSimpleTypeMap
public org.refcodes.struct.SimpleTypeMap toSimpleTypeMap()
Returns theSimpleTypeMap
representation of thisTransmission
. In case this Transmission hasTransmission
children, then the children are queried as well and contained in the resultingSimpleTypeMap
. The aliases of the accordingTransmission
instances represent the resulting path to aTransmission
's final simple type.- Specified by:
toSimpleTypeMap
in interfaceTransmission
- Returns:
- The
SimpleTypeMap
representing thisTransmission
and (if any) its children, with the according aliases forming the paths to theTransmission
's values.
-
fromTransmission
public int fromTransmission(Sequence aSequence, int aOffset) throws TransmissionException
(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
public void receiveFrom(InputStream aInputStream, OutputStream aReturnStream) throws IOException, TransmissionException
(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.
