Class STNodePredicates

java.lang.Object
io.nosqlbench.nb.spectest.traversal.STNodePredicates
All Implemented Interfaces:
STDebug, Function<com.vladsch.flexmark.util.ast.Node,Optional<List<com.vladsch.flexmark.util.ast.Node>>>
public class STNodePredicates extends Object implements Function<com.vladsch.flexmark.util.ast.Node,Optional<List<com.vladsch.flexmark.util.ast.Node>>>, STDebug

STNodePredicates is a convenient wrapper around STNodePredicate evaluation so that creating a Node scanner is a one-liner. Any of the supported types for STNodePredicate are valid, in addition to numbers which reference previous positions in the argument list (zero-indexed.)

This allows for existing node matchers to be re-used by reference. For Example, a specification like 

new NodePredicates("__\\w__",0,0)
represents a regular expression which would match "__a__" or "__b__" and then two more subsequent matches against similar content, for a total of 3 consecutive matching nodes.
