Example 26 with EventListener

use of javax.jcr.observation.EventListener in project sling by apache.

the class ScriptableTestsProvider method activate.

protected void activate(final Map<String, Object> props) throws Exception {

    for (int i = 0; i < allowedRoots.length; i++) {
        if (!allowedRoots[i].endsWith("/")) {

        }
    }
