All Implemented Interfaces:

QueryParser

public class JcrQomQueryParser
extends JcrSql2QueryParser

A parser for the JCR Query Object Model language.

The JCR 2.0 specification does not explicitly define a textual query language or grammar for the Query Object Model (the grammar in the specification is written more in terms of the code of a Java-like language). However, per the Section 6.9 of the JCR 2.0 specification, the QueryManager.createQuery(String, String) method

"is used for languages that are string-based (i.e., most languages, such as JCR-SQL2) as well as for the for the string serializations of non-string-based languages (such as JCR- JQOM)"

Since the string serialization (that is, the toString() form) of our QueryCommand and related abstract query model objects are in fact equivalent to JCR-SQL2, this parser simply extends the JcrSql2QueryParser.
