goog.dom.pattern.Matcher Classgoog.dom.pattern.Matcher()Given a set of patterns and a root node, this class tests the patterns in
parallel.
It is not (yet) a smart matcher - it doesn't do any advanced backtracking.
Given the pattern DIV, SPAN the matcher will not match
DIV, DIV, SPAN because it starts matching at the first
DIV, fails to match SPAN at the second, and never
backtracks to try again.
It is also possible to have a set of complex patterns that when matched in
parallel will miss some possible matches. Running multiple times will catch
all matches eventually.
.addPattern(pattern, callback)Adds a pattern to be matched. The callback can return an object whose keys are processing instructions.
pattern {goog.dom.pattern.AbstractPattern}
callback {Function}
.match(node)Match the set of patterns against a match tree.
node {Node}
