Constructor Detail

AbstractMagicBytesTransmission

public AbstractMagicBytesTransmission(String aAlias,
                                      TransmissionMetrics aTransmissionMetrics)

Constructs an according instance for magic bytes of the given length. 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.

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

AbstractMagicBytesTransmission

public AbstractMagicBytesTransmission(String aAlias,
                                      int aMagicBytesLength)

Constructs an AbstractMagicBytesTransmission for magic bytes of the given length.

Parameters:

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

aMagicBytesLength - The length of the magic bytes sequence.

AbstractMagicBytesTransmission

public AbstractMagicBytesTransmission(String aAlias,
                                      String aMagicBytes)

Constructs an AbstractMagicBytesTransmission with the according magic bytes (retrieved from the given String).

Parameters:

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

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

AbstractMagicBytesTransmission

public AbstractMagicBytesTransmission(String aAlias,
                                      String aMagicBytes,
                                      Charset aCharset)

Constructs an AbstractMagicBytesTransmission with the according magic bytes (retrieved from the given String).

Parameters:

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

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.

AbstractMagicBytesTransmission

public AbstractMagicBytesTransmission(String aAlias,
                                      byte[] aMagicBytes)

Constructs an AbstractMagicBytesTransmission with the according magic bytes.

Parameters:

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

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

Method Detail

setPayload

public void setPayload(byte[] aValue)

Sets the magic bytes as of setMagicBytes(byte[]).

Specified by:

setPayload in interface org.refcodes.mixin.PayloadAccessor.PayloadMutator<byte[]>

getAlias

public String getAlias()

Specified by:

getAlias in interface org.refcodes.mixin.AliasAccessor

getMagicBytes

public byte[] getMagicBytes()

Returns the magic bytes as stored by this instance.

Specified by:

getMagicBytes in interface org.refcodes.mixin.MagicBytesAccessor

Returns:

The according magic bytes.

setMagicBytes

public void setMagicBytes(byte[] aMagicBytes)

Sets the magic bytes to be stored by this instance.

Specified by:

setMagicBytes in interface org.refcodes.mixin.MagicBytesAccessor.MagicBytesMutator

Parameters:

aMagicBytes - The according magic bytes to store.

setMagicBytes

public void setMagicBytes(String aMagicBytes)

Sets the magic bytes from the provided String to be stored by this instance (uses the TransmissionMetrics.DEFAULT_ENCODING) for byte conversion).

Specified by:

setMagicBytes in interface org.refcodes.mixin.MagicBytesAccessor.MagicBytesMutator

Specified by:

setMagicBytes in interface MagicBytesAccessor.MagicBytesMutator

Parameters:

aMagicBytes - The String from which to copy the according magic bytes from.

setMagicBytes

public void setMagicBytes(String aMagicBytes,
                          Charset aCharset)

Sets the magic bytes from the provided String to be stored by this instance.

Specified by:

setMagicBytes in interface org.refcodes.mixin.MagicBytesAccessor.MagicBytesMutator

Parameters:

aMagicBytes - The String from which to copy the according magic bytes from.

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

toMagicBytesString

public String toMagicBytesString()

Retrieves the String representation of the given magic bytes using the latest provided Charset for conversion or the TransmissionMetrics.DEFAULT_ENCODING in case no Charset has been provided.

Returns:

The String representation of the magic bytes.

toTransmission

public Sequence toTransmission()

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.

Specified by:

toTransmission in interface Transmission

Returns:

The according instance's Sequence.

getMagicBytesLength

public int getMagicBytesLength()

Retrieves the magic bytes length from the magic bytes magic bytes length property.

Specified by:

Returns the magic bytes as of getMagicBytes().

Specified by:

getPayload in interface org.refcodes.mixin.PayloadAccessor<byte[]>

toSchema

public Schema toSchema()

Retrieves the Schema representing the Transmission. Retrieving a Schema 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.

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.
