Class BaseNotificationConnector

  • All Implemented Interfaces:
    IConnector, INotificationConnector
    public abstract class BaseNotificationConnector
extends BaseConnector
implements INotificationConnector
    This base class 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.

        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.

                                    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.
