Note: declarations declared as <tt>const</tt> are wrapped as read-only variables and
will be accessed using a getter as described in the previous section. They
are not wrapped as constants.
The exception to this rule are static const integral values defined within a class/struct, where they are wrapped as constants, eg:.

<b>Compatibility Note:</b> In SWIG-1.3.19 and earlier releases, the constants were generated into the module class and the constants interface didn't exist.
Backwards compatibility is maintained as the module class implements the constants interface (even though some consider this type of interface implementation to be bad practice):

SWIG favours generating Java code over JNI code as Java code is compiled into byte code and avoids the costly string operations needed in JNI code.
This approach has a downside though as the proxy class might get collected before the native method has completed.
You might notice above that there is an additional parameters with a underscore postfix, eg <tt>jarg1_</tt>.
These are added in order to prevent <a href="java_pgcpp">premature garbage collection when marshalling proxy classes</a>.
