Interface INotificationConnector

  • All Superinterfaces:
    IConnector
    All Known Implementing Classes:
    BaseNotificationConnector
    public interface INotificationConnector
extends IConnector
    This interface describes an instance of a connection between a notification engine and ManifoldCF's standard "pull" ingestion agent. Each instance of this interface is used in only one thread at a time. Connection Pooling on these kinds of objects is performed by the factory which instantiates repository connectors from symbolic names and config parameters, and is pooled by these parameters. That is, a pooled connector handle is used only if all the connection parameters for the handle match. Implementers of this interface should provide a default constructor which has this signature: xxx(); Connectors are either configured or not. If configured, they will persist in a pool, and be reused multiple times. Certain methods of a connector may be called before the connector is configured. This includes basically all methods that permit inspection of the connector's capabilities. The purpose of the notification connector is to notify people of job interruptions.

      • requestInfo

        boolean requestInfo​(Configuration output,
                    java.lang.String command)
             throws ManifoldCFException
        Request arbitrary connector information. This method is called directly from the API in order to allow API users to perform any one of several connector-specific queries. These are usually used to create external UI's. The connector will be connected before this method is called.
        Parameters:
        output - is the response object, to be filled in by this method.
        command - is the command, which is taken directly from the API request.
        Returns:
        true if the resource is found, false if not. In either case, output may be filled in.
        Throws:
        ManifoldCFException

        Parameters:
        out - is the output to which any HTML should be sent.
        locale - is the locale the output is preferred to be in.
        ds - is the current document specification for this job.
        connectionSequenceNumber - is the unique number of this connection within the job.
        tabsArray - is an array of tab names. Add to this array any tab names that are specific to the connector.
        Throws:
        ManifoldCFException

                             java.io.IOException
        Output the specification body section. This method is called in the body section of a job page which has selected a repository connection of the current type. Its purpose is to present the required form elements for editing. The coder can presume that the HTML that is output from this configuration will be within appropriate <html>, <body>, and <form> tags. The name of the form is always "editjob". The connector will be connected before this method can be called.
        Parameters:
        out - is the output to which any HTML should be sent.
        locale - is the locale the output is preferred to be in.
        ds - is the current document specification for this job.
        connectionSequenceNumber - is the unique number of this connection within the job.
        actualSequenceNumber - is the connection within the job that has currently been selected.
        tabName - is the current tab name. (actualSequenceNumber, tabName) form a unique tuple within the job.
