Class DoubleHolder

public final class DoubleHolder extends Object implements Streamable

A holder for CORBA double that is mapped into java double. 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
doublevalue
The double (CORBA double) value, held by this DoubleHolder.
Constructor Summary
DoubleHolder()
Constructs an instance of DoubleHolder, initializing value to 0.0.
DoubleHolder(double initial_value)
Constructs an instance of DoubleHolder, initializing value to the given double.
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.

Constructor Detail

DoubleHolder

public DoubleHolder()
