Abstract Value Members

  1. abstract def identifier: DataFlowMetadataExtensionIdentifier

    Used to identify an extension instance on the flow

  2. abstract def preExecutionManipulation(flow: S): S

    Function that is called just before a flow is executed.

    Function that is called just before a flow is executed. This function can be used to: * Validate a flow (using the metadata state) * Change the flow in some way (using the metadata state)

    This function can be called multiple times until all invocations stabilise. Ensure you remove the extension from the flow to prevent the extension being called again.
