Example 11 with JoinPredicate

use of org.teiid.query.sql.lang.JoinPredicate in project teiid by teiid.

the class TestJoinPredicate method testEquals2.

/**
 * Test <code>equals()</code> method of <code>JoinPredicate</code> to
 * verify it properly evaluates the equality of two
 * <code>JoinPredicate</code> objects.

 * This test ensures that two different <code>JoinPredicate</code> objects
 * that were constructed with the same join type and with the same
 * compound criteria evaluate as equal.
