Class ByteHolder

java.lang.Object
  extended by org.omg.CORBA.ByteHolder
All Implemented Interfaces:
Streamable

public final class ByteHolder
extends Object
implements Streamable

A holder for CORBA octet that is mapped into java byte. The holders have several application areas. The end user usually sees them implementing CORBA methods where the primitive type is passed by reference. While CORBA (or, for example, C) supports this, the java does not and a wrapper class is required.


Field Summary
 byte value
          The byte (CORBA octet) value, held by this ByteHolder.
 
Constructor Summary
ByteHolder()
          Constructs an instance of ByteHolder, initializing value to 0x0 .
ByteHolder(byte initial_value)
          Constructs an instance of ByteHolder, initializing value to the given byte.
 
Method Summary
 void _read(InputStream input)
          Fill in the value field by reading the required data from the given stream.
 TypeCode _type()
          Returns the TypeCode, corresponding the CORBA type that is stored using this holder.
 void _write(OutputStream output)
          Write the value field to the given stream.

Field Detail

value

public byte value
The byte (CORBA octet) value, held by this ByteHolder.

Constructor Detail

ByteHolder

public ByteHolder()
Constructs an instance of ByteHolder, initializing value to 0x0 .


ByteHolder

public ByteHolder(byte initial_value)
Constructs an instance of ByteHolder, initializing value to the given byte.

Parameters:
initial_value - a value that will be assigned to the value field.
Method Detail

_read

public void _read(InputStream input)
Fill in the value field by reading the required data from the given stream. For octet, the functionality is delegated to InputStream.read_octet().

Specified by:
_read in interface Streamable
Parameters:
input - the input stream to read from.

_type

public TypeCode _type()
Returns the TypeCode, corresponding the CORBA type that is stored using this holder.

Specified by:
_type in interface Streamable

_write

public void _write(OutputStream output)
Write the value field to the given stream. For octet, the functionality is delegated to OutputStream.write_octet(byte).

Specified by:
_write in interface Streamable
Parameters:
output - the output stream to write into.
