public ContentDescription build(Node n,
                                XMLGraph xg,
                                boolean enable_automaton,
                                boolean include_text,
                                Automaton project_names,
                                NodeKind[] nodekind,
                                boolean use_cache,
                                boolean force_approx)

Converts the given node. Results are cached by the converter when use_cache is true.

Parameters:

n - node

xg - XML graph

enable_automaton - if true, construct full content automaton, otherwise only represent text in the content automaton

include_text - if true, include all text including whitespace around elements

project_names - if non-null then project onto these names, otherwise include all element names

nodekind - node kinds for the XML graph, if null then search through all nodes

use_cache - enable caching if true

force_approx - force into approximation mode

Returns:

content description where content automaton is constructed if enable_automaton is true, element names is non-null if project_names is null, text is set if a text node is encountered (ignoring ws flag on element nodes), and non-ws-text is set if any non whitespace text node is encountered (and project_names is non-null or enable_automaton is false)
