libjna-java-doc 4.5.1-1 (arm64 binary) in ubuntu cosmic

 JNA provides Java programs easy access to native shared libraries without
 writing anything but Java code - no JNI or native code is required. This
 functionality is comparable to Windows' Platform/Invoke and Python's ctypes.
 Access is dynamic at runtime without code generation.

 This package contains the Javadoc API documentation.
