Constructor Details

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(String aAlias,
 DECORATEE aDecoratee,
 TransmissionMetrics aTransmissionMetrics)

Enriches the provided decoratee with magic bytes of the given length to be prefixed. 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:

aAlias - The alias which identifies the content of this segment.

aDecoratee - The decoratee which to be prefixed with magic bytes.

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

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(DECORATEE aDecoratee,
 int aMagicBytesLength)

Enriches the provided Section with magic bytes of the given length to be prefixed.

Parameters:

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytesLength - The length of the magic bytes sequence.

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(DECORATEE aDecoratee,
 String aMagicBytes)

Enriches the provided Section with magic bytes being prefixed (retrieved from the given String).

Parameters:

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytes - The String to be stored by this instance as magic bytes (uses the TransmissionMetrics.DEFAULT_ENCODING) for byte conversion).

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(DECORATEE aDecoratee,
 String aMagicBytes,
 Charset aCharset)

Enriches the provided Section with magic bytes being prefixed (retrieved from the given String).

Parameters:

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytes - The String to be stored by this instance as magic bytes.

aCharset - The Charset to use when converting the String to a byte array.

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(DECORATEE aDecoratee,
 byte[] aMagicBytes)

Enriches the provided Section with the given magic bytes being prefixed.

Parameters:

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytes - The magic bytes to be prefixed.

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(String aAlias,
 DECORATEE aDecoratee,
 int aMagicBytesLength)

Enriches the provided Section with magic bytes of the given length to be prefixed.

Parameters:

aAlias - The alias which identifies the content of this segment.

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytesLength - The length of the magic bytes sequence.

MagicBytesSectionDecorator

public MagicBytesSectionDecorator(String aAlias,
 DECORATEE aDecoratee,

Parameters:

aAlias - The alias which identifies the content of this segment.

aDecoratee - The Section which is to be prefixed with magic bytes.

aMagicBytes - The String to be stored by this instance as magic bytes (uses the TransmissionMetrics.DEFAULT_ENCODING) for byte conversion).

Method Details

fromTransmission

public void fromTransmission(Sequence aSequence,
 int aOffset,
 int aLength)
                      throws BadMagicBytesSequenceException,
TransmissionException

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

Specified by:

fromTransmission in interface Section

Parameters:

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

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

aLength - The length of data assigned by the Sequence.

Throws:

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

BadMagicBytesSequenceException

receiveFrom

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

Default implementation harnessing the Section.fromTransmission(Sequence, int) method. (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 Section

Specified by:

receiveFrom in interface Section.SectionMixin

Parameters:

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

aLength - The length of data assigned by the byte array.

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 InputStream bytes cannot be processed.

withPayload

public MagicBytesSectionDecorator<DECORATEE> withPayload(byte[] aValue)

Specified by:

withPayload in interface org.refcodes.mixin.PayloadAccessor.PayloadBuilder<byte[],PayloadTransmission<byte[]>>

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<DECORATEE extends Section>

Specified by:

toSchema in interface Transmission

Overrides:

toSchema in class AbstractMagicBytesTransmissionDecorator<DECORATEE extends Section>

Returns:

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