When a destination region has an item enter the region, PRT will ask the source region about the item that just transitioned.
If the source region:
Is managed by another PRT process |
That process will be requested for information about that item. |
Has no information about the Item |
PRT will request the information from an external process. These requests will be continuously made each time the Item moves, until a response is available. The external process is defined to PRT through configuration data. The configuration of an external process is optional. PRT will only request an external process to provide information on serialized items. |
Transitions. |
