Java Access Bridge 2.0.2 Release Notes

This document summarizes changes made in Java Access Bridge 2.0.2.

Java Access Bridge 2.0.2 includes updated APIs to support 64-bit Windows systems. Assistive Technology vendors will need to update their applications in order use the new 64-bit Java Access Bridge APIs. Java Access Bridge 2.0.2 also includes packages to support 32-bit Windows systems (legacy systems).
 

API Changes

Java Access Bridge 2.0.2 includes a new set of APIs in order to support 64-bit systems. However, the changes to the API are specific to parameters passed in API calls; there are no name changes in the API.

Assistive Technologies must recompile their applications with the new header files provided in the source.

Objects of type jobject are now passed as jlong. The typedef JOBJECT64 is either a jobject or jlong
depending on whether ACCESSBRIDGE_ARCH_LEGACY is defined. See the AccessBridgePackages.h header file.

For usage examples, see the JavaFerret.cpp example:

void HandlePropertyChildChange(
  long vmID, PropertyChangeEvent event,
  AccessibleContext ac, JOBJECT64 oldChild, JOBJECT64 newChild);
 
void HandlePropertyActiveDescendentChange(
  long vmID, PropertyChangeEvent event, AccessibleContext ac,
  JOBJECT64 oldActiveDescendent, JOBJECT64 newActiveDescendent);
