Using TCP Adapters with Ensemble - InterSystems Documentation

3Using the TCP Counted Outbound AdapterEnsLib.TCP.CountedOutboundAdapter contains methods that an Ensemble business operation can call to read or write blocksof data across the TCP connection. Ensemble acts as a TCP client exchanging blocks of data with a TCP listener. The blocklength specified in the first 4 bytes of the block. This convention allows an Ensemble business operation to send requeststo an external TCP server for fulfillment. The adapter makes no decisions about the data it relays out to the external system.It simply maps the request from the business operation to a format that is acceptable to the external system.This chapter explains how to use the EnsLib.TCP.CountedOutboundAdapter. It discusses the following topics:• Background Information• Using the Adapter• Creating a New Business Operation Class• Sample Business Operation Class Code• Available Helper Methods• Adapter Settings3.1 Background InformationYou can simply set up the EnsLib.TCP.CountedOutboundAdapter as instructed in the next section, “Using the Adapter.”However, some developers want more details about how a business operation communicates with its configured adapter.This section provides those details.Using TCP Adapters with Ensemble 13
