Process Flow keeps its data in a memory called Process Flow Context, which is used by the process flow during its execution. When the process flow takes any data from the context, it uses the context source activity. Context Source is used to read a variable and stream it out to other activities of the process flow. In addition, Context Source can also read a file from the repository (WebDAV or File) and pass it to other activities. Similarly, when process flow sends any data to the context, it uses the context target activity.
To create a Context Source/Target activity:
- Click hierarchy structure in the Repository View panel. Expand the Activities list and click Source. A list of source activities is displayed.
Select Context Source. Drag the Context Source to the Graph Canvas Area. A small image of the activity is displayed in the Graph Canvas Area.
- In the Graph Canvas area, right-click the Context Source and select View Properties. This displays all properties for the context source at the Bottom Pane.
A list of properties and their descriptions are displayed in the table below:
Properties | Description |
|---|---|
Document Repository | This property specifies whether the data to be taken from the value of process flow variable, or from the document repository. If it is set to false, the data is taken from the Process Flow variable, specified by the Parameter Name property. If it is set to true, the source data is taken from the repository file specified by the File Name (with full Path) Property. Specify the path of the document repository and the name of the repository file, from which the data is to be taken, in this field. The repository can be WebDAV repository or file repository. To know more about repository, refer to the Administrator Guide. |
eventContextEnabled | By default it is set to NO. If you want to pass any data from event, select Yes. For example, if you are triggering the process flow using Mail Event and you want to pass the content of the mail to the process flow, set this property to yes. To know about events, refer to the Creating Trigger and Events section. |
Format | Data Format; whether Plain Type or Record Type. Select Plain Type, if data is in Byte Stream. Select Record type, if data is in record format. |
Label | Label of the Context Source Activity displayed in the Graph Canvas area. |
Name | Name of the Context Source activity. By default, it is same as the Process Variable name. |
Repository Folder | Name and path of the WebDAV folder. This property is displayed only if the Document Repository property is set to True. |
ParameterName | Select the name of the Process Flow Variable, whose value is to be taken as context source. This property is applicable only when the Document Repository Property is set to False. |
Source | Name of the stream being consumed by this activity. This property is applicable only for Context Target. It is non-editable. |
streamNames | Name of the output stream name. This property is applicable only for Context Source. It is non-editable. |
Sync | Specifies whether the activity will be executed in Sync mode or A-sync mode. |
Type | Activity Type; whether Context Source or Context Target. By Default Context Source is selected. If you want to use it as Context Target, select Context Target from the dropdown list. |
Version Control | It specifies whether versions are to be maintained for the repository file, which is created by context target. This property is displayed only if the Document Repository property is set to True. If this property is set to false, then the versions are not maintained. If it is set to True, then all versions are tracked. |
