Using Standard Adapters
Software adapters provide the interface between Apama applications and middleware buses and other message sources. Apama provides a number of standard adapters.
With the Apama Database Connector (ADBC), Apama applications can store and retrieve data in standard database formats. You can retrieve data using the ADBCHelper API or the ADBC Event API to execute general database queries or retrieve the data for playback purposes using the Apama Data Player.
The Apama Web Services Client adapter is a SOAP-based adapter that allows Apama applications to invoke Web services.
The Apama File adapter uses the Apama Integration Adapter Framework (IAF) to read information from text files and write information to text files by means of Apama events. This lets you read files line-by-line from external applications or write formatted data as required by external applications.
The File Transport, String Codec and Null Codec plug-ins are useful examples of how event transports and codecs can be written. These plug-ins are provided for your convenience as an aid to testing and the development of custom adapters that make use of them ‘as is'. They are available in both C and Java.
