Example 90 with SiddhiAppRuntime

use of org.ballerinalang.siddhi.core.SiddhiAppRuntime in project ballerina by ballerina-lang.

the class CustomJoinWindowTestCase method testJoinWindowWithSameWindow.

/**
 * Behaviour of traditional Window and Window are different in join  with themselves.
 * Traditional Windows joins always maintain two windows and the event is passed to them one after
 * the other. Therefore, when left window receives a current event right window will bbe empty and
 * if an event is expired from left window it can join with right window since it will not expire at the same
 * time. Since Window maintains only one instance, when an event arrives to the window it will
 * be compared to the internal event chunk, where the current event will match with itself.
 * When an event expires, it will be immediately removed from the internal event chunk so that,
 * when joined with the window, the expired event will not match with itself.
 *
 * @throws InterruptedException throw exception if interrupted the input handler sender.
