Class LongHolder

java.lang.Object
  extended by org.omg.CORBA.LongHolder
All Implemented Interfaces:
Streamable

public final class LongHolder
extends Object
implements Streamable

A holder for CORBA long long that is mapped into java long. The holders have several application areas. The end user usually sees them implementing CORBA methods where the primitive type is passed by reference. While CORBA (or, for example, C) supports this, the java does not and a wrapper class is required.


Field Summary
 long value

Constructor Summary
LongHolder()
          Constructs an instance of LongHolder, initializing value to 0 .
LongHolder(long initial_value)

Method Summary
 void _read(InputStream input)
          Fill in the value field by reading the required data from the given stream.
 TypeCode _type()
          Returns the TypeCode, corresponding the CORBA type that is stored using this holder.

Constructor Detail

LongHolder

public LongHolder()
Constructs an instance of LongHolder, initializing value to 0 .


LongHolder

public LongHolder(long initial_value)
Constructs an instance of LongHolder, initializing value to the given long.

Parameters:
initial_value - a value that will be assigned to the value field.
Method Detail

_read

public void _read(InputStream input)
Fill in the value field by reading the required data from the given stream. For long long, the functionality is delegated to InputStream.read_longlong().

Specified by:
_read in interface Streamable
Parameters:
input - the input stream to read from.

_type

public TypeCode _type()
Returns the TypeCode, corresponding the CORBA type that is stored using this holder.

Specified by:
_type in interface Streamable

_write

public void _write(OutputStream output)
Write the value field to the given stream. For long long, the functionality is delegated to OutputStream.write_longlong(long).

Specified by:
_write in interface Streamable
Parameters:
output - the output stream to write into.
