Table Row To Variable Run-for-time Loop Start

Loop start tablerow to variable node, which will run until a specified time period has elapsed. The user can specify the node behaviour in the event of missing values, and the time (dd:hh:mm:ss) at which the last iteration will start before. The loop will execute until that time is reached, when no further rows will be processed. If connected to a Run-to-time Loop end, the unprocessed rows will be available directly in the final port of the loop end node.

This node was developed by Vernalis Research . For feedback and more information, please contact knime@vernalis.com

Options

Missing Variable Values

Fail
Node execution will fail on encountering a missing value
Use defaults
Default values will be substituted on encountering a missing value
Skip (Add to unprocessed rows table)
Node execution will skip a row on encountering a missing value. The skipped row will be included in the 'unprocessed rows' table of a closing Timed Loop node.
Skip (Don't add to unprocessed rows table)
Node execution will skip a row on encountering a missing value.
Default Integer Value
The default value to be used for missing values in Integer columns
Default Double Value
The default value to be used for missing values in Double columns
Default String Value
The default value to be used for missing values in String columns

Expiry time

End time (dd:hh:mm:ss):
The time period after which execution will finish (dd:hh:mm:ss)
Start value of iteration counter
Allows the user to manually set the value at which the iteration counter will start (does not affect the processing of the table!)
