Recall from App
Synopsis
This operator retrieves the specified object from a RapidMiner AI Hub App or the current RapidMiner Studio session. Ojects can be stored by using the Publish to App operator.
Description
The Recall from App operator can be used for retrieving the specified object from a RapidMiner AI Hub App or the current RapidMiner Studio session. The name of the object is specified through thenameparameter. The Recall from App operator is always used in combination with the Publish to App operator. For the Recall from App operator to retrieve an object, first it is necessary that the object has to be stored by using the Publish to App operator. The name of the object is specified when the object is stored. The same name (innameparameter) should be specified in the Recall from App operator to retrieve that object. The same object can be retrieved multiple times, even from within another process, if theremove from appparameter of the Recall from App operator is not set to true. When an object was stored by the Publish to App operator once, it can be recalled at any point in the RapidMiner AI Hub App or the current RapidMiner Studio session. But care should be taken that the execution order of operators is such that the Publish to App operator for an object always executes before the Recall from App operator for that object. The combination of these two operators can be used to build complex RapidMiner AI Hub Apps where an input object is stored once and used in completely different parts of the App later on.
Differentiation
Publish to App
The Recall from App operator is always used in combination with the Publish to App operator. The Publish to App operator stores the input object in the RapidMiner AI Hub App and the Recall from App operator retrieves the stored object when required.
Input
通过
It is not compulsory to connect any object with this port. Any object connected at this port is delivered without any modifications to the output port. This operator can have multiple inputs. When one input is connected, another通过input port becomes available which is ready to accept another input (if any). The order of inputs remains the same. The object supplied at the first通过input port of the Recall from App operator is available at the first通过output port.
Output
result
The specified object is retrieved from the RapidMiner AI Hub App or the current RapidMiner Studio session and is delivered through this output port.
通过
The objects that were given as input are passed without changing to the output through this port. It is not compulsory to attach this port to any other port, the specified object is retrieved from the RapidMiner AI Hub App even if this port is left without connections. The Recall from App operator can have multiple outputs. When one output is connected, another通过输出端口可用which is ready to deliver another output (if any). The order of outputs remains the same. The object delivered at the first通过input port of the Recall from App operator is delivered at the first通过output port
Parameters
Name
The name of the required object is specified through this parameter. This name should be the same name that was used while storing the object in an earlier call of the operator Publish to App.
Remove from dashboard
If this parameter is set to true, the specified object is removed from the RapidMiner AI Hub App or the current RapidMiner Studio session after it has been retrieved. In such a case the object can be retrieved just once. If this parameter is set to false, the object remains in the RapidMiner AI Hub App even after retrieval. Thus the object can be retrieved by multiple Recall from App operators.
