Method Detail

readIdentifiableSequence

public static void readIdentifiableSequence(List<Object> container,
                            IdentifiableFactoryFinder finder,
                            InputStream istr)

Read the count from is, then read count Identifiables from is using the factory. Add each constructed Identifiable to container.

writeIdentifiableSequence

public static void writeIdentifiableSequence(List<Object> container,
                             OutputStream os)

Write all Identifiables that we contain to os. The total length must be written before this method is called.

writeOutputStream

public static void writeOutputStream(OutputStream dataStream,
                     OutputStream os)

Helper method that is used to extract data from an output stream and write the data to another output stream. Defined as static so that it can be used in another class.

getEncapsulationStream

public static InputStream getEncapsulationStream(InputStream is)

Helper method to read the octet array from is, deencapsulate it, and return as another InputStream. This must be called inside the constructor of a derived class to obtain the correct stream for unmarshalling data.

readOctets

public static byte[] readOctets(InputStream is)

Helper method that reads an octet array from an input stream. Defined as static here so that it can be used in another class.

writeEncapsulation

public static void writeEncapsulation(WriteContents obj,
                      OutputStream os)
