public class Query
extends java.lang.Object

A Query is a generic way to retrieve IPersistentObjects. Unlike the Query in Elexis through 2.x, this is not just a wrapper around an SQL expression. Instead, a Query now is a List of Query.Terms, each connected to the previous term with a Connector (AND, OR, AND NOT, OR NOT), and each consisting of a field, a comparison operator and a match expression. A Query is executed by sending it to a PersistentObjectManager as argument to executeQuery();
