Class RegExp

java.lang.Object

org.elasticsearch.common.lucene.RegExp

public class RegExp
extends Object

Simple wrapper for RegExp that avoids throwing StackOverflowErrors when working with regular expressions as this will crash an Elasticsearch node. Instead, these StackOverflowErrors are turned into IllegalArgumentExceptions which elasticsearch returns as a http 400.
