Class FixedHolder

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

public final class FixedHolder
extends Object
implements Streamable

A holder for CORBA fixed that is mapped into java BigDecimal. 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
 BigDecimal value
          The BigDecimal (CORBA fixed) value, held by this FixedHolder.
 
Constructor Summary
FixedHolder()
          Constructs an instance of FixedHolder, initializing value to null.
FixedHolder(BigDecimal initial_value)
          Constructs an instance of FixedHolder, initializing value to the given BigDecimal.
 
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.
 void _write(OutputStream output)
          Write the value field to the given stream.

Field Detail

value

public BigDecimal value
The BigDecimal (CORBA fixed) value, held by this FixedHolder.

Constructor Detail

FixedHolder

public FixedHolder()
Constructs an instance of FixedHolder, initializing value to null.


FixedHolder

public FixedHolder(BigDecimal initial_value)
Constructs an instance of FixedHolder, initializing value to the given BigDecimal.

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 fixed, the functionality is delegated to InputStream.read_fixed().

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. The scale and digits are set corresponding the scale and used digits of the value that is currently stored or left with default value 0 if the value is not set.

Specified by:
_type in interface Streamable

_write

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

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