java.lang.Object | +--org.omg.CORBA.Any
Serves as a container for any data that can be
described in IDL or for any IDL primitive type.
An Any
object is used as a component of a
NamedValue
object, which provides information about
arguments or return values in requests, and which is used to define
name/value pairs in Context
objects.
An Any
object consists of two parts:
TypeCode
object describing the type of the data
value contained in the Any
object. For example,
a TypeCode
object for an array contains
a field for the length of the array and a field for
the type of elements in the array. (Note that in this case, the
second field of the TypeCode
object is itself a
TypeCode
object.)
A large part of the
For a given primitive type X, these methods are:

Any
also has methods for
getting and setting the type code,
for testing two Any
objects for equality,
and for reading an Any
object from a stream or
writing it to a stream.

Note that using this method to set the type code wipes out the
value if there is one. The method
is provided primarily so that the type may be set properly for
IDL out
parameters. Generally, setting the type
is done by the insert_X
methods, which will set the type
to X if it is not already set to X.
