Timed Loop End (Upto 4 ports)

Loop end node to partner with 'Run-to-time' and 'Run-for-time' loop start nodes. Rows which were not processed before the loop execution finished as a result of the time setting of the loop start node are made available at the last output port. The behaviour of non-connected optional ports is goverened by they user settings

Options

Row key policy: How should row keys, which must be unique, be generated in the output table? ' Generate new Row IDs ' generates new row IDs sequential in the form Row0, Row1 etc.; ' Unique Row IDs by appending suffix ' appends '_Iter#' and the iteration number to the incoming Row ID; ' Leave Row IDs unchanged ' leaves incoming Row IDs unchanged. Nodes which previously had 'Uniquify Row IDs' set, will follow the second option
Add iteration column: Adds a column to the output table containing the iteration number, starting with 0
Ignore empty input tables: Selecting this option means the structure of empty input tables at the specified port will be ignored and they will not cause the node to fail
Allow changing column types: Tables in which the column names remain constant, but the types change between iterations will be allowed to pass. The type of columns changed will be the simplest type common to all input types. A message will be sent to the console explaining any failures
Allow changing table specs: Tables in which more complex changes to the table structure occur will be allowed to pass. This setting overrides the 'Allow changing column types' setting. If this option is not set, a message will be sent to the console explaining any failures.
Return inactive branches for disconnected optional ports: If selected, optional input ports which are disconnected will have inactive branches as output ports. Otherwise, an empty, columnless table will result
