Class BooleanHolder

java.lang.Object
  |
  +--org.omg.CORBA.BooleanHolder
All Implemented Interfaces:
Streamable
public final class BooleanHolder
extends Object
implements Streamable

A Holder class for a boolean that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL boolean as an "out" or "inout" parameter, the programmer must pass an instance of BooleanHolder as the corresponding parameter in the method invocation; for "inout" parameters, the programmer must also fill the "in" value to be sent to the server. Before the method invocation returns, the ORB will fill in the value corresponding to the "out" value returned from the server.

If myBooleanHolder is an instance of BooleanHolder, the value stored in its value field can be accessed with myBooleanHolder.value.

Since:
JDK1.2

Field Summary
 boolean value
          The boolean value held by this BooleanHolder object.
 
Constructor Summary
BooleanHolder()
          Constructs a new BooleanHolder object with its value field initialized to false.
BooleanHolder(boolean initial)
          Constructs a new BooleanHolder object with its value field initialized with the given boolean.
 
Method Summary
 void _read(InputStream input)
          Reads unmarshalled data from input and assigns it to this BooleanHolder object's value field.
 TypeCode _type()
          Retrieves the TypeCode object that corresponds to the value held in this BooleanHolder object.
 void _write(OutputStream output)
          Marshals the value in this BooleanHolder object's value field to the output stream output.
