Example 1 with IntersectAxis

use of org.sirix.service.xml.xpath.expr.IntersectAxis in project sirix by sirixdb.

the class PipelineBuilder method addIntExcExpression.

/**
 * Adds a intersect or a exception expression to the pipeline.
 *
 * @param mTransaction Transaction to operate with.
 * @param mIsIntersect true, if expression is an intersection
 */
public void addIntExcExpression(final XdmNodeReadTrx mTransaction, final boolean mIsIntersect) {
