Class BooleanHolder

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

public final class BooleanHolder
extends Object
implements Streamable

A holder for CORBA boolean that is mapped into java boolean. 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

Constructor Summary
BooleanHolder()
          Constructs an instance of BooleanHolder, initializing value to false.
BooleanHolder(boolean initial_value)

Field Detail

value

public boolean value
The boolean (CORBA boolean) value, held by this BooleanHolder.

Constructor Detail

BooleanHolder

public BooleanHolder()
Constructs an instance of BooleanHolder, initializing value to false.


BooleanHolder

public BooleanHolder(boolean initial_value)
Constructs an instance of BooleanHolder, initializing value to the given boolean.

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 boolean, the functionality is delegated to InputStream.read_boolean().

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 boolean, the functionality is delegated to OutputStream.write_boolean(boolean).

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