org.apache.jackrabbit.oak.query.QueryFormatter

public class QueryFormatter
extends java.lang.Object

Formatter for JCR queries in order to make them easier to read. Formatting is done on a best-effort basis. Warning: Care was taken to not add newlines inside string literals and so on, but there is still no guarantee that the formatted query is semantically equal to the original one. It is NOT recommended to run queries that are returned by these methods.
