Class RegexNodeNameRule

java.lang.Object

com.northconcepts.datapipeline.foundations.pipeline.tree.detect.RegexNodeNameRule

All Implemented Interfaces:

NodeNameRule

public class RegexNodeNameRule
extends Object
implements NodeNameRule

Classifies names matching a caller-supplied regular expression as dynamic. The expression must match the whole name (row\d+ matches row12 but not xrow12).

Use it as a build-time rule so matching names collapse to wildcard nodes while the tree loads:

 Tree.loadXml(file, TreeDetectionStrategy.standard(true).addNodeNameRule(new RegexNodeNameRule("row\\d+")));
 

or as an affix segment rule so sibling middles the standard rules do not recognize (for example 3A, 5B) can still derive a collapse pattern.
