Overview:
When this object is in pull mode and it is ready to receive its next flowitem, it will first evaluate this Pull Strategy field to determine which input port to open. If the Pull Strategy field returns a zero (0) for the input port number, then it will open all of its input ports. When an input port is opened, the OnInOpen event of this object will execute immediately if the connected upstream output port is already open, or the OnInOpen event will fire in the future when the upstream output port is eventually opened. When the OnInOpen event fires, the PullRequirement will be evaluated, determining which flowitem will actually get pulled in.
