public final class CharHolder extends Object implements Streamable
The Holder for Char. For more information on Holder files, see "Generated Files: Holder Files".

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

JDK1.2
