Once the callback OnPush for an input port has been invoked, the element that has been pushed can be retrieved via this method. After GrabT(Inlet) has been called the port is considered to be empty, and further calls to GrabT(Inlet) will fail until the port is pulled again and a new element is pushed as a response. The method IsAvailable(Inlet) can be used to query if the port has an element that can be grabbed or not.
