Example 1 with NestedAxis

use of org.sirix.axis.NestedAxis in project sirix by sirixdb.

the class ExpressionSingle method add.

/**
 * Adds a new Axis to the expression chain. The first axis that is added has to be stored till a
 * second axis is added. When the second axis is added, it is nested with the first one and builds
 * the execution chain.
