/**
 * Object model for Java expressions.
 *
 * This object model is used when the linq4j system is analyzing
 * queries that have been submitted using methods on the
 * {@link org.apache.calcite.linq4j.Queryable} interface. The system attempts
 * to understand the intent of the query and reorganize it for
 * efficiency; for example, it may attempt to push down filters to the
 * source SQL system.
