Pull Requirement   


This field is a boolean expression returning either true (1) or false (0). It is evaluated in the OnInOpen event of this object whenever an input port becomes ready. An input port is ready when it is open AND the upstream output port that it is connected to is open. The connection becomes ready when either the input port is opened, OR the upstream output port is opened (assuming the paired port is already open). This Pull Requirement expression will be evaluated for each ready flowitem within the object connected to the input port which just became ready causing the OnInOpen event to fire. If the expression returns a true (1), then the ready flowitem will be pulled in through the ready input port.

Access variables:

current: the current object

item: the ready flowitem for which the Pull Requirement is currently being evaluated

port: the number of the input port that became ready
