Connect to DOORS from outside, the tool provides a C-based API called CAPI.dll that connects to a DOORS-internal DXL-server. In our case, we developed a JNI-based Java to C mapping to connect the Java-Adapter with the CAPI. The following picture shows an architecural overview of the communication layer of the adapter.

The following diagram shows a runtime benchmark test between pure DXL-scripts and the adapter functions. The test creates 1000 items in each case and was repeated 100 times. Thus, the diagram shows average values.
