Building Java bindings for ADLX
This guide outlines the steps to build a Java binding wrapper for ADLX, a prerequisite to programming with ADLX in a Java application.
Prerequisite(s)
-
ADLX SDK is installed.
-
Visual Studio 2019 is installed.
-
swigwin 4.0.2 is installed, and the path to the swigwin 4.0.2 installation is added to the Path user environment variable.
-
OpenJDK 17 is installed.
-
The path to the OpenJDK 17 installation is added to the JAVA_HOME system environment variable.
-
The bin path for the OpenJDK 17 installation is added to the Path system environment variable.
To build ADLX bindings in Java
-
Create and name a folder for your Java ADLX binding wrapper, for example
ADLXJavaBind. -
Create a new file in the
ADLXJavaBindfolder and title itADLXJavaBind.i. -
Edit
ADLXJavaBind.iand add the SDK header files for the interfaces you wish to wrap by using the SWIG input format.To create bindings for event notifications, turn ondirectorwrapping callback for the respective listener interfaces.For example,
Copied!
feature("director") IADLXDisplayListChangedListener;Note: Refer to the Java samples ADLXJavaBind.i file for an example of a Java binding.
-
Create a C++ Dynamic Link Library project named
ADLXJavaBindand configure the project as follows:-
Key
Value
Observations
VC++ Directories > Include Directories
$(JAVA_HOME)/include and $(JAVA_HOME)/include/win32
Add path of java include and path of java/win32 include
C/C++ > Precompiled Header
Not Using Precompiled Headers
Do not use precompiled headers
-
-
Add the
ADLXJavaBind.ifile to the project. -
Right-click the
ADLXJavaBind.ifile and select Properties from the menu. In the Properties dialog select Configuration Properties> General> Item Type> Custom Build Tool.Set the configuration as follows:
-
Key
Value
Observations
Command Line
if not exist $(SolutionDir)out mkdir $(SolutionDir)out swig.exe -c++ -java -package out -outdir ../out/ ADLXJavaBind.i
Invoke SWIG.exe to build
ADLXJavaBind.ifileOutputs
%(Filename)_wrap.cxx
Set output file name format
-
-
Build the project.
Result: The following files are added to the
ADLXJavaBindproject output folder:-
ADLXJavaBind_wrap.hfile. -
ADLXJavaBind_wrap.cxxfile. -
Several *.java files.
-
-
Add the following files to the project:
-
ADLXJavaBind_wrap.h -
ADLXJavaBind_wrap.cxx -
SDK/Platform/Windows/WinAPIs.cpp -
SDK/ADLXHelper/Windows/Cpp/ADLXHelper.h -
SDK/ADLXHelper/Windows/Cpp/ADLXHelper.cpp
-
-
Rebuild the project.
Result: The
ADLXJavaBind.dllis built in the"$(SolutionDir)$(Platform)$/(Configuration)/"folder.
