Input Merger v2.0

The input event is a field name/value pair. If the name in a pair matches one of the names in the order parameter, the corresponding value is stored for output. When all of the names in order have been matched at least once, the set of stored values is output. Note that multiple matches (and stores) can occur for any name. In this case, the latest store overwrites the value of the previous store, ensuring that each field has the latest value.

If the incremental update parameter is set, then further outputs are generated on any input that matches a field in the order parameter. If the incremental update parameter is not set, then further outputs are only sent once all fields have been received again (that is, the old input values are discarded). The id field increments with each output event, in either mode.

Parameter	Description
order	A comma-separated list of up to 8 field names to match against names on the input stream. The order in which the names are listed is the order in which they appear on the output. Note that fields may not contain commas, but they may be repeated or be an empty string.
incremental input	If true, a change to a single field listed in the order parameter results in an output being generated once all input fields have been received at least once, that is, the first output is still generated only when all fields have been received.

Operation	Description
start	Activate merger.
stop	Deactivate merger.

in	name	Field name
in	value	Field value

The out feed specifies the selected individual values from the input feed, in the order they are listed by the order parameter.
