interface XEnumeration in module com::sun::star::container::

(Global Index)

Syntax

interface XEnumeration : com::sun::star::uno::XInterface ;

Description

provides functionality to enumerate the contents of a container.

An object that implements the XEnumeration interface generates a series of elements, one at a time. Successive calls to the XEnumeration::nextElement method return successive elements of the series.

For example (Java), to print all elements of a vector aVect :

 for ( XEnumeration xEnum = aVect.elements() ;
 xEnum.hasMoreElements() ; )
 {
 System.out.println( xEnum.nextElement() );
 }

If the object changed, the behavior of the enumeration is not specified. This is not a remote interface.
