## org.omg.CORBA
Class CharHolder

    java.lang.Object
      |
      +--org.omg.CORBA.CharHolder

All Implemented Interfaces:
  Streamable

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`.

Since:
  JDK1.2

Field Summary
`char` | `value` The `char` value held by this `CharHolder` object.

Constructor Summary
`CharHolder()` Constructs a new `CharHolder` object with its `value` field initialized to `0`.
`CharHolder(char initial)` Constructs a new `CharHolder` object for the given `char`.

Method Summary
`void` | `_read(InputStream input)` Reads from `input` and initalizes the value in this `CharHolder` object with the unmarshalled data.
`TypeCode` | `_type()` Returns the `TypeCode` object corresponding to the value held in this `CharHolder` object.
`void` | `_write(OutputStream output)` Marshals to `output` the value in this `CharHolder` object.
