Detailed Description

A DynamicContext that maintains the focus, a sequence of items.

CurrentItemContext implements both the outer and inner focus. The focus is one of the things that characterizes the XPath language. The focus is what's iterated over in a predicate, whose current item can be received via the context item expression, .(the dot), and whose size is retrievable via the function fn:last().

Functions

◆ currentItem()

Item CurrentItemContext::currentItem ( ) const
virtual

Returns the item that fn:current() returns.

Hence, this is not the focus, and very different from the focus.
