Detailed Description

An object that implements the Enumeration interface generates a series of elements, one at a time.

Successive calls to the nextElement method return successive elements of the series.

For example, to print all elements of a vector v: <blockquote>

                 for (Enumeration e = v.elements() ; e.hasMoreElements() ;) {
                     System.out.println(e.nextElement());<br>
                 }

</blockquote>

Methods are provided to enumerate through the elements of a vector, the keys of a hashtable, and the values in a hashtable. Enumerations are also used to specify the input streams to a SequenceInputStream.

NOTE: The functionality of this interface is duplicated by the Iterator interface. In addition, Iterator adds an optional remove operation, and has shorter method names. New implementations should consider using Iterator in preference to Enumeration.

Member Function Documentation

virtual bool java::util::Enumeration::hasMoreElements (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )  [virtual]

Tests if this enumeration contains more elements. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: true if and only if this enumeration object contains at least one more element to provide; false otherwise.

virtual ::java::lang::Object java::util::Enumeration::nextElement (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

Returns the next element of this enumeration if this enumeration object has at least one more element to provide. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: the next element of this enumeration.
