Method Summary

Modifier and Type	Method and Description
static InputStream	getEncapsulationStream(ORB orb, InputStream is) Helper method to read the octet array from is, deencapsulate it, and return as another InputStream.
static <E extends Identifiable> void	readIdentifiableSequence(List<E> container, IdentifiableFactoryFinder<E> finder, InputStream istr) Read the count from is, then read count Identifiables from is using the factory.
static byte[]	readOctets(InputStream is) Helper method that reads an octet array from an input stream.
static void	writeEncapsulation(WriteContents obj, OutputStream os)
static <E extends Identifiable> void	writeIdentifiableSequence(List<E> container, OutputStream os) Write all Identifiables that we contain to os.
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.

Method Detail

readIdentifiableSequence

public static <E extends Identifiable> void readIdentifiableSequence(List<E> container,
                                                                     IdentifiableFactoryFinder<E> 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 <E extends Identifiable> void writeIdentifiableSequence(List<E> 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(ORB orb,
                                                 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)
