All Implemented Interfaces:

Serializable, org.refcodes.mixin.BodyAccessor<AllocSegmentBody<?>>, org.refcodes.mixin.BodyAccessor.BodyMutator<AllocSegmentBody<?>>, org.refcodes.mixin.BodyAccessor.BodyProperty<AllocSegmentBody<?>>, org.refcodes.mixin.LengthAccessor, org.refcodes.mixin.Resetable, org.refcodes.numerical.EndianessAccessor, org.refcodes.schema.Schemable, AllocLengthAccessor, LengthWidthAccessor, Segment, Transmission, Transmission.TransmissionMixin

public class AllocSegmentHead
extends AbstractReferenceeLengthSegment<AllocSegmentBody<?>>
implements org.refcodes.mixin.BodyAccessor.BodyProperty<AllocSegmentBody<?>>

An AllocSegmentHead provides the allocation length for a AllocSegmentBody. Therefore the AllocSegmentHead references a AllocSegmentBody. The AllocSegmentHead manages the Sequence regarding the allocation length whereas the AllocSegmentBody manages the decorated Segment by harnessing the allocation length provided by the AllocSegmentHead.

Constructor Details

AllocSegmentHead

protected AllocSegmentHead(TransmissionMetrics aTransmissionMetrics)

AllocSegmentHead

public AllocSegmentHead(AllocSegmentBody<?> aBody,
 TransmissionMetrics aTransmissionMetrics)

Constructs the head with the given body. The configuration attributes are taken from the TransmissionMetrics configuration object, though only those attributes are supported which are also supported by the other constructors!

Parameters:

aBody - The body referenced by this head.

aTransmissionMetrics - The TransmissionMetrics to be used for configuring this instance.

AllocSegmentHead

protected AllocSegmentHead()

Constructs an empty head with a width of TransmissionMetrics.DEFAULT_LENGTH_WIDTH bytes used to specify the body's length and a TransmissionMetrics.DEFAULT_ENDIANESS endian representation of the body's length.

AllocSegmentHead

protected AllocSegmentHead(org.refcodes.numerical.Endianess aEndianess)

Constructs an empty head with a width of TransmissionMetrics.DEFAULT_LENGTH_WIDTH bytes used to specify the body's length and the provided Endianess representation of the body's length.

Parameters:

aEndianess - The Endianess to be used for length values.

AllocSegmentHead

protected AllocSegmentHead(int aLengthWidth,
 org.refcodes.numerical.Endianess aEndianess)

Constructs an empty head with a width of TransmissionMetrics.DEFAULT_LENGTH_WIDTH bytes used to specify the body's length and the provided Endianess representation of the body's length.

Parameters:

aLengthWidth - The width (in bytes) to be used for length values.

aEndianess - The Endianess to be used for length values.

AllocSegmentHead

protected AllocSegmentHead(int aLengthWidth)

Constructs an empty head with the given number of bytes used to specify the body's length and a TransmissionMetrics.DEFAULT_ENDIANESS endian representation of the body's length.

Parameters:

aLengthWidth - The width (in bytes) to be used for length values.

AllocSegmentHead

public AllocSegmentHead(AllocSegmentBody<?> aBody,
 org.refcodes.numerical.Endianess aEndianess)

Constructs the head with the given body and a width of TransmissionMetrics.DEFAULT_LENGTH_WIDTH bytes used to specify the body's length and the provided Endianess representation of the body's length.

Parameters:

aBody - The body referenced by this head.

aEndianess - The Endianess to be used for length values.

AllocSegmentHead

public AllocSegmentHead(AllocSegmentBody<?> aBody,
 int aLengthWidth,
 org.refcodes.numerical.Endianess aEndianess)

Constructs the head with the given body and with the given number of bytes used to specify the body's length and the provided Endianess representation of the body's length.

Parameters:

aBody - The body referenced by this head.

aLengthWidth - The width (in bytes) to be used for length values.

aEndianess - The Endianess to be used for length values.

AllocSegmentHead

public AllocSegmentHead(AllocSegmentBody<?> aBody,
 int aLengthWidth)

Constructs the head with the given body and with the given number of bytes used to specify the body's length and a TransmissionMetrics.DEFAULT_ENDIANESS endian representation of the body's length.

Parameters:

aBody - The body referenced by this head.

aLengthWidth - The width (in bytes) to be used for length values.

Method Details

fromTransmission

public int fromTransmission(Sequence aSequence,
 int aOffset)
                     throws TransmissionException

(Re-)initializes this instance with the the given Sequence data.

Specified by:

fromTransmission in interface Segment

Overrides:

fromTransmission in class AbstractReferenceeLengthSegment<AllocSegmentBody<?>>

Parameters:

aSequence - The Sequence data from which to (re-)initialize this instance.

aOffset - The offset where to start processing the provided Sequence.

Returns:

The index after the last offset into the given Sequence processed by this method.

Throws:

TransmissionException - thrown in case a given Sequence cannot be processed.

receiveFrom

public void receiveFrom(InputStream aInputStream,
 OutputStream aReturnStream)
                 throws IOException

(Re-)initializes this instance by receiving the according Sequence from the given InputStream. Implementations providing error correction methods use the provided feedback OutputStream to do some sort of "stop-and-wait ARQ" or apply similar methods to ensure correctness of the received data.

Specified by:

receiveFrom in interface Segment

Overrides:

receiveFrom in class AbstractReferenceeLengthSegment<AllocSegmentBody<?>>

Parameters:

aInputStream - The InputStream from which to read the instance's (re-)initialization Sequence from.

aReturnStream - An OutputStream 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 the InputStream caused problems.

TransmissionException - thrown in case a given transmission cannot be processed.

toSchema

public SerialSchema toSchema()

Specified by:

toSchema in interface org.refcodes.schema.Schemable

Specified by:

public AllocSegmentBody<?> getBody()

Specified by:

getBody in interface org.refcodes.mixin.BodyAccessor<AllocSegmentBody<?>>
