org.omg.CORBA_2_3.portable

Class InputStream

Implemented Interfaces:
AutoCloseable, Closeable

public abstract class InputStream
extends InputStream

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, and only one unimplemented interface, ValueFactory, needs it as a parameter. 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 Details

read_abstract_interface

public Object read_abstract_interface()
Read the abstract interface. An abstract interface can be either CORBA value type or CORBA object and is returned as an abstract java.lang.Object. As specified in OMG specification, this reads a single boolean and then delegates either to read_Object() (for false) or to read_value() (for true).
Returns:
an abstract interface, unmarshaled from the stream.

read_value

public Serializable read_value()
Read a value type structure, extracting the repository id from the input stream itself. The repository id is optional in the value type record, but it must be present for this method to succeed. The OutputStream of this implementation always stores the repository id. The casts the streams ORB into a CORBA 2.3 ORB and then searched for a suitable value factory, where it delegates the functionality. If you know the exact class or can create an unitialised instance of the value type, it is recommended (faster) to use read_value(Class) or read_value(Serializable) instead.
Returns:
an value type structure, unmarshaled from the stream

read_value

public Serializable read_value(Serializable unitialised_value)
Read a value type structure content, when the unitialised instance is passed as a parameter. It is a fastest method to read a value type. As the type is known, the repository Id in the input stream is optional an not required. The codebase, if present, is also ignored. The passed instance must implement either CustomMarshal for the user-defined reading operations or StreamableValue for the standard (generated by IDL compiler) reading operations.
Parameters:
unitialised_value - the unitialised value.
Returns:
same value, filled in by the stream content.

read_value

public Serializable read_value(String repository_id)
Read a value type structure, having the given repository id. The casts the streams ORB into a CORBA 2.3 ORB and then searched for a suitable value factory, where it delegates the functionality. If you know the exact class or can create an unitialised instance of the value type, it is recommended (faster) to use read_value(Class) or read_value(Serializable) instead.
Parameters:
repository_id - a repository id of the value type.
Returns:
an value type structure, unmarshaled from the stream

read_value

public Serializable read_value(BoxedValueHelper helper)
Use the provided boxed value helper to read the value.
Parameters:
helper - a helper for reading the value from the stream.
Returns:
an value type structure, unmarshaled from the stream.
