Developing custom adapters
The custom adapters interface makes it possible for users to develop adapters with as much functionality as those provided with the product.
Adapter registration and the library virtual table
The first step required to develop an adapter is to add the adapter to the adapters.xml registration file.
Initializing the adapter
InitializeLibrary provides an entry point by which any global structures, critical sections, or lists that are required by the adapter can be initialized.
Point to adapter methods
After your adapter is loaded, you call the virtual table (vtable) structure to obtain pointers to the methods.
Adapter registration file
The adapters.xml registration file contains a single tag for each adapter, including a number of attributes to provide information about the adapter.
Additional adapter methods
There are a number of additional methods that are part of the Transformation Extender Programming Interface library that are of particular relevance to adapter developers.
Passing data to and from maps
Data is passed between adapters and the engine through stream objects. From the adapter perspective, there is no need to create these stream objects; they are already created when either the Get or Put method is called.
Listener scenario overview
These are listener scenario examples that demonstrate the flow of calls for input events.
Threads, connections, and transactions overview
It is important to understand how threads, connections, and transactions interact.
