Examples with InvalidQueryException javax.jcr.query.InvalidQueryException used on opensource projects

Example 51 with InvalidQueryException

use of javax.jcr.query.InvalidQueryException in project jackrabbit by apache.

the class QueryObjectModelFactoryImpl method createQuery.

/**
 * Creates a query with one or more selectors.
 * <p>
 * If <code>source</code> is a selector, that selector is the <i>default
 * selector</i> of the query.  Otherwise the query does not have a default
 * selector.
 *
 * @param source     the node-tuple source; non-null
 * @param constraint the constraint, or null if none
 * @param orderings  zero or more orderings; null is equivalent to a
 *                   zero-length array
 * @param columns    the columns; null is equivalent to a zero-length array
 * @return the query; non-null
 * @throws javax.jcr.query.InvalidQueryException
 *                                       if the query is invalid
 * @throws javax.jcr.RepositoryException if the operation otherwise fails
