|
|
Adds a value to a named value in an event pattern or stream until it ends. Repeats this with new values until the value stream ends.
|

ClassMethods::
|
||
|
|
|
||
|
|
method::new
|
||
|
|
argument::name
|
||
|
|
the named value in the event pattern or stream to multiply.
|
||
|
|
argument::value
|
||
|
|
The value, pattern, stream or array to multiply with. The resulting stream ends when this incoming stream ends.
|
||
|
|
argument::pattern
|
||
|
|
The event pattern or stream within which to multiply the new values.
