/**
* 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 {@link 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
* {@link JcrSql2QueryParser}.
