Class OutputStream

public abstract class OutputStream extends OutputStream

This class defines a new CDR input stream methods, added since CORBA 2.3. This class is abstract; no direct instances can be instantiated. Also, up till v 1.4 inclusive there are no methods that would return it directly. However since 1.3 all methods, declared as returning an org.omg.CORBA.portable.InputStream actually return the instance of this derived class and the new methods are accessible after the casting operation.

Method Summary
void	write_abstract_interface(Object an_interface) Writes an abstract interface to the stream.
void	write_value(Serializable value) Writes a value type into the output stream.
void	write_value(Serializable value, BoxedValueHelper helper) Write value to the stream using the boxed value helper.
void	write_value(Serializable value, Class clz) Writes a value type into the output stream, stating it is an instance of the given class.
void	write_value(Serializable value, String repository_id) Writes a value type into the output stream, stating it has the given repository id.

Method Detail

write_abstract_interface

public void write_abstract_interface(Object an_interface)

Writes an abstract interface to the stream. An abstract interface can be eithe CORBA object or value type and is written as a union with the boolean discriminator (false for objects, true for value types). The object from value is separated by fact that all values implement the {@link ValueBase} interface. Also, the passed parameter is treated as value it it does not implement CORBA Object.

Parameters: an_interface an abstract interface to write.

write_value

public void write_value(Serializable value)

Writes a value type into the output stream. The value type must implement either {@link CustomValue} (for user-defined writing method) or {@link StreamableValue} (for standard writing using code, generated by IDL compiler). The written record will have a repository id, matching the class of the passed object. The codebase will not be written.

Parameters: value a value type object to write.

write_value

public void write_value(Serializable value, BoxedValueHelper helper)

Write value to the stream using the boxed value helper. The value type must implement either {@link CustomValue} (for user-defined writing method) or {@link StreamableValue} (for standard writing using code, generated by IDL compiler).

Parameters: value a value to write. helper a helper, responsible for the writing operation.

write_value

public void write_value(Serializable value, Class clz)

Writes a value type into the output stream, stating it is an instance of the given class. The written record will have a repository id, matching the passed class. The codebase will not be written. It the object being written is an instance of the different class, this results writing two Id inheritance hierarchy. The value type must implement either {@link CustomValue} (for user-defined writing method) or {@link StreamableValue} (for standard writing using code, generated by IDL compiler).

Parameters: value a value type object to write.

write_value

public void write_value(Serializable value, String repository_id)

Writes a value type into the output stream, stating it has the given repository id. The value type must implement either {@link CustomValue} (for user-defined writing method) or {@link StreamableValue} (for standard writing using code, generated by IDL compiler).

Parameters: repository_id a repository id of the value type. value a value type object to write.
