Keeps track of a count that can be incremented and decremented and always stays within a given range.
When the composition starts or this node is added to a running composition, the count is the value of the
Set Count input port.
Increment— When this port receives an event, the count is incremented by this port’s value.
Decrement— When this port receives an event, the count is decremented by this port’s value.
Set Count— When this port receives an event, the count is changed to this port’s value.
Minimum— The minimum value that the count may have.
Maximum— The maximum value that the count may have.
Wrap Mode— The way to adjust the count when it falls outside the range.
If an event reaches both the
Set Count port and the
Decrement port, the count is set, and the increment or decrement is ignored. After the count is set, wrapping is applied.
For the Integer type, the minimum and maximum are inclusive (a closed interval) — when incrementing and wrapping, the output value can become exactly the maximum followed by exactly the minimum. But for the Real type, the minimum and maximum are exclusive (a half-closed interval) — when incrementing, the output value can become exactly the maximum, but cannot become exactly the minimum.
