Examples with HighLow org.apache.apex.malhar.lib.util.HighLow used on opensource projects

Example 1 with HighLow

use of org.apache.apex.malhar.lib.util.HighLow in project apex-malhar by apache.

the class Range method endWindow.

/**
 * Emits the range. If no tuple was received in the window, no emit is done
 * Clears the internal data before return
 */
@Override
public void endWindow() {
    if ((low != null) && (high != null)) {
        HighLow tuple = new HighLow(getValue(high.doubleValue()), getValue(low.doubleValue()));
