NAME

TPath::Context - the context in which a node is evaluated during a search

VERSION

version 1.001

DESCRIPTION

Basically a data structure holding all the different bits of information that may be useful to selectors, predicates, or attributes during the evaluation of a node. This class simplifies method signatures -- instead of passing a list of parameters one passes a single context.

A TPath::Context is a blessed array rather than a hash, and it is a non-Moose class, for a little added efficiency.

METHODS

previous

Returns the context of the node selected immediately before the context node.

first

Returns the first context in the selection history represented by this context.

n

The context node.

i

The TPath::Index.

path

The previous nodes selected in the course of selecting the context node. These ancestor nodes are in reverse order, so the node's immediate predecessor is at index 0.

to_string

The stringification of a context is the stringification of its node.
