public class FileSection
extends AbstractPayloadSection<File>
implements PayloadSection<File>

A FileSection represents a File on the file system and can be used to receive or to transmit a File. Using a Supplier, one can use for example a StringSection's value (as of AbstractPayloadSection.getPayload()) to determine the underlying File name dynamically. Whenever the underlying File is to be accessed, then the Supplier is called (if provided) to construct the according File dynamically. This way, a file name provided by a StringSection can be used for the FileSection within the same transmission.

Constructs a FileSection, the underlying File is created on demand dynamically using the provided Supplier.

Parameters:

aBasePath - The base path for the path provided by the Supplier.

aFilePathSupplier - The Supplier of the file path of File representing the FileSection. Whenever the underlying file is to be accessed, then the Supplier is called to construct the according File.

Method Details

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<SerialSchema>

Specified by:

toSchema in interface Transmission

Returns:

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

fromTransmission

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

receiveFrom

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

(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.

getLength

public int getLength()

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()

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. ATTENTION: Use this method with care as all of the File's content is loaded into the Sequence (and therewith into memory) as a byte array!

Specified by:

toSequence in interface Transmission

Returns:

The according instance's Sequence.

transmitTo

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

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

Specified by:

transmitTo in interface Transmission.TransmissionMixin

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.

withPayload

public PayloadTransmission<File> withPayload(File aPayload)

Specified by:

withPayload in interface org.refcodes.mixin.PayloadAccessor.PayloadBuilder<File,PayloadTransmission<File>>

toPayloadFile

public File toPayloadFile()

Determines whether we have a "dynamic" File as of a Supplier being or a "static" File (or a file path).

Returns:

The according File.
