org.refcodes.serial.AbstractMagicBytesTransmissionMultiplexer<CHILD>

All Implemented Interfaces:

Serializable, Iterable<CHILD>, org.refcodes.mixin.ChildrenAccessor<CHILD[]>, org.refcodes.mixin.LengthAccessor, org.refcodes.mixin.Schemable<SerialSchema>, Transmission

Direct Known Subclasses:

MagicBytesSectionMultiplexer, MagicBytesSegmentMultiplexer

public class AbstractMagicBytesTransmissionMultiplexer<CHILD extends Transmission>
extends Object
implements Transmission, Iterable<CHILD>, org.refcodes.mixin.ChildrenAccessor<CHILD[]>

The AbstractMagicBytesTransmissionMultiplexer dispatches a transmission to one of the aggregated Transmission instances depending on the magic number provided by the transmission. A transmission is passed to each of the aggregated Transmission instances till one Transmission accepts the transmission, e.g. until a Transmission does not throw a BadMagicBytesException. Attention: A Transmission throwing a TransmissionException other than a BadMagicBytesException is considered to be responsible for the transmission so that dispatching is *not* continued with the succeeding Transmission! The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission.

AbstractMagicBytesTransmissionMultiplexer

public AbstractMagicBytesTransmissionMultiplexer(Collection<CHILD> aSegments,
 int aReadLimit)

aReadLimit - the maximum limit of bytes that can be read from a given InputStream before the InputStream cannot be rolled back.

Method Details

getLength

public int getLength()

Returns the length of the responsible Transmission: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Determines the overall length of this Transmission. In case of nested Transmission instances, all length values from all sub-segments are accumulated to the result as well.

Specified by:

getLength in interface org.refcodes.mixin.LengthAccessor

Specified by:

getLength in interface Transmission

Returns:

The (overall) length of the Transmission (including any sub-segments).

toSequence

public Sequence toSequence()

Returns the responsible Transmission's transmission: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Provides the Sequence representation of this Transmission. In case of nested Transmission instances, all Sequence representations from all sub-segments are accumulated to the result as well. Caution, the Transmission (or its nested Transmission instances) may be backed by the returned Sequence.

Specified by:

toSequence in interface Transmission

Returns:

The according instance's Sequence.

transmitTo

public void transmitTo(OutputStream aOutputStream,
 InputStream aReturnStream)
                throws IOException

Transmits to the responsible Transmission: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Transmits the Sequence representing the implementing type's instance to the given OutputStream. Implementations providing error correction methods use the provided feedback InputStream to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the transmitted data.

Specified by:

transmitTo in interface Transmission

Parameters:

aOutputStream - The OutputStream where to write this instance's Sequence to.

aReturnStream - An InputStream 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 the OutputStream caused problems.

toSchema

public SerialSchema toSchema()

Retrieves the SerialSchema representing the Transmission. Retrieving a SerialSchema is useful when analyzing and debugging data structures such as a AllocSectionDecoratorSegment instance to help document, learn and verify on the structure (as well as the content) of that very AllocSectionDecoratorSegment.

Specified by:

toSchema in interface org.refcodes.mixin.Schemable<CHILD extends Transmission>

Specified by:

toSchema in interface Transmission

Returns:

The SerialSchema representation of the implementing type for debugging and verification (or documentation) purposes.

toSimpleTypeMap

public org.refcodes.struct.SimpleTypeMap toSimpleTypeMap()

Returns the responsible Transmission's SimpleTypeMap representation: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Returns the SimpleTypeMap representation of this Transmission. In case this Transmission has Transmission children, then the children are queried as well and contained in the resulting SimpleTypeMap. The aliases of the according Transmission instances represent the resulting path to a Transmission's final simple type.

Specified by:

toSimpleTypeMap in interface Transmission

Returns:

The SimpleTypeMap representing this Transmission and (if any) its children, with the according aliases forming the paths to the Transmission's values.

transmitTo

public void transmitTo(OutputStream aOutputStream)
                throws IOException

Transmits to the responsible Transmission: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Transmits the Sequence representing the implementing type's instance to the given OutputStream. This is a convenience method in case there is no feedback InputStream available (actually the Transmission.transmitTo(OutputStream, InputStream) method is invoked with null for the feedback InputStream). Override Transmission.transmitTo(OutputStream, InputStream) for your custom transmitting functionality.

Specified by:

transmitTo in interface Transmission

Parameters:

aOutputStream - The OutputStream where to write this instance's Sequence to.

Throws:

IOException - thrown in case writing data to the OutputStream caused problems.

transmitTo

public void transmitTo(SerialTransceiver aSerialTransceiver)
                throws IOException

Transmits to the responsible Transmission: The last Transmission which was responsible for a transmission's magic bytes will be the responsible Transmission till another Transmission claims responsibility for a transmsision's magic bytes. Initially the first Transmission passed to this instance is the responsible Transmission. Transmits the Sequence representing the implementing type's instance to the given SerialTransceiver's OutputStream. Implementations providing error correction methods use the provided SerialTransceiver's feedback InputStream to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the transmitted data.This is a convenience method (actually the Transmission.transmitTo(OutputStream, InputStream) method is invoked). Override Transmission.transmitTo(OutputStream, InputStream) for your custom transmitting functionality.

Specified by:

transmitTo in interface Transmission

Parameters:

aSerialTransceiver - The SerialTransceiver providing the OutputStream where to write this instance's Sequence to and providing the InputStream being the return channel to handle "stop-and-wait ARQ".

Throws:

IOException - thrown in case writing data to the OutputStream caused problems.

iterator

public Iterator<CHILD> iterator()

Specified by:

iterator in interface Iterable<CHILD extends Transmission>

getChildren

public CHILD[] getChildren()

Specified by:

getChildren in interface org.refcodes.mixin.ChildrenAccessor<CHILD extends Transmission>

getCallee

public CHILD getCallee()

The last Transmission to which the dispatch was transferred, e.g. which matched the dispatch's magic bytes till another Transmission claims responsibility for a dispatch's magic bytes..

Returns:

Returns the Transmission to which the dispatch was transferred.
