  +--org.omg.CORBA.FloatHolder

public final class FloatHolder

extends Object

implements Streamable

A Holder class for a float that is used to store "out" and "inout" parameters in IDL methods. If an IDL method signature has an IDL float as an "out" or "inout" parameter, the programmer must pass an instance of FloatHolder 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 myFloatHolder is an instance of FloatHolder, the value stored in its value field can be accessed with myFloatHolder.value.

Since:

JDK1.2
