Formatters Currently Available from SAP

The adapter framework provides numerous formatter modules that come standard with Event Stream Processor. You can re-use these modules to create a custom adapter instance.

The Input Datatype column specifies the format of the incoming data, while the Output Datatype column specifies the format that the formatter translates this incoming data into.

AdapterRow is a container for one or more records or rows as they flow from one module (transporter, formatter, or ESP connector) to the next. You can add multiple records as objects within a List of a single AdapterRow object. The AdapterRow has a timestamp and block flags that control how its records are communicated to and from Event Stream Processor. See Envelopes and Transactions for additional details.

AepRecord is the class that represents stream records. This is the type that the ESP publisher expects as the data member in the AdapterRow instances that it receives from the previous module. This is also the type used in the AdapterRow instances that the ESP subscriber passes on to the next module.
