Examples of java.awt.RenderingHints.containsKey()

java.awt.RenderingHints.containsKey()
Returns true if this RenderingHints contains a mapping for the specified key. @param key key whose presence in this RenderingHints is to be tested. @return true if this RenderingHints contains a mapping for the specified key. @exception ClassCastException if the key can notbe cast to RenderingHints.Key

    harness.check(h1.size() == 2);

    harness.check(h1.get(RenderingHints.KEY_ANTIALIASING).equals(RenderingHints.VALUE_ANTIALIAS_ON));
