ValueBaseHolder

public final class ValueBaseHolder extends Object implements org.omg.CORBA.portable.Streamable
The Holder for ValueBase. For more information on Holder files, see "Generated Files: Holder Files".

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

Fields Summary
public Serializable
value
The java.io.Serializable value held by this ValueBaseHolder object.
Constructors Summary
public ValueBaseHolder()
Constructs a new ValueBaseHolder object with its value field initialized to 0.
public ValueBaseHolder(Serializable initial)
Constructs a new ValueBaseHolder object with its value field initialized to the given java.io.Serializable.

param
initial the java.io.Serializable with which to initialize the value field of the newly-created ValueBaseHolder object

	value = initial;
Methods Summary
public void_read(org.omg.CORBA.portable.InputStream input)
Reads from input and initalizes the value in the Holder with the unmarshalled data.

param
input the InputStream containing CDR formatted data from the wire

	value = ((org.omg.CORBA_2_3.portable.InputStream)input).read_value();
public org.omg.CORBA.TypeCode_type()
Returns the TypeCode object corresponding to the value held in the Holder.

return
the TypeCode of the value held in the holder

	return ORB.init().get_primitive_tc(TCKind.tk_value);
public void_write(org.omg.CORBA.portable.OutputStream output)
Marshals to output the value in the Holder.

param
output the OutputStream which will contain the CDR formatted data

	((org.omg.CORBA_2_3.portable.OutputStream)output).write_value(value);
