An <code>Any</code> object is used as a component of a <code>NamedValue</code> object, which provides information about arguments or return values in requests, and which is used to define name/value pairs in <code>Context</code> objects.<p> An <code>Any</code> object consists of two parts: <OL> <LI>a data value <LI>a <code>TypeCode</code> object describing the type of the data value contained in the <code>Any</code> object. For example, a <code>TypeCode</code> 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 <code>TypeCode</code> object is itself a <code>TypeCode</code> object.) </OL> <P> <a name="anyOps"</a> A large part of the <code>Any</code> class consists of pairs of methods for inserting values into and extracting values from an <code>Any</code> object. <P> For a given primitive type X, these methods are: <dl> <dt><code><bold> void insert_X(X x)</bold></code> <dd> This method allows the insertion of an instance <code>x</code> of primitive type <code>X</code> into the <code>value</code> field of the <code>Any</code> object. Note that the method <code>insert_X</code> also resets the <code>Any</code> object's <code>type</code> field if necessary. <dt> <code><bold>X extract_X()</bold></code> <dd> This method allows the extraction of an instance of type <code>X</code> from the <code>Any</code> object. <BR> <P> This method throws the exception <code>BAD_OPERATION</code> under two conditions: <OL> <LI> the type of the element contained in the <code>Any</code> object is not <code>X</code> <LI> the method <code>extract_X</code> is called before the <code>value</code> field of the <code>Any</code> object has been set </OL> </dl> <P> There are distinct method pairs for each primitive IDL data type (<code>insert_long</code> and <code>extract_long</code>, <code>insert_string</code> and <code>extract_string</code>, and so on).<BR> <P> The class <code>Any</code> also has methods for getting and setting the type code, for testing two <code>Any</code> objects for equality, and for reading an <code>Any</code> object from a stream or writing it to a stream. <BR><P><DL><DT><B>Since: </B><DD>JDK1.2</DD><DT><B>See Also: </B><DD><A HREF="../../../serialized-form.html#org.omg.CORBA.Any">Serialized
