[Java] Bug fix: Overloaded C++ functions which cannot be overloaded in Java
once again issue a warning.
11/14/2002: cheetah (William Fulton)
[Java] Handling of NULL pointers is improved. A java null object will now
be translated to and from a NULL C/C++ pointer by default. Previously when
wrapping:
class SomeClass {...};
void foo(SomeClass *s);
and it was called from Java with null:
modulename.foo(null)
a Java NullPointerException was thrown. Extra typemaps had to be written in
order to obtain a NULL pointer to pass to functions like this one. Now the
default wrapping will detect 'null' and translate it into a NULL pointer.
Also if a function returns a NULL pointer, eg:
SomeClass *bar() { return NULL; }
Then this used to be wrapped with a SomeClass proxy class holding a NULL
pointer. Now null is returned instead. These changes are subtle but useful.
The original behaviour can be obtained by using the original typemaps:
%typemap(javaout) SWIGTYPE {
return new $&javaclassname($jnicall, true);
}
%typemap(javaout) SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] {
return new $javaclassname($jnicall, $owner);
}
%typemap(javagetcptr) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] %{
protected static long getCPtr($javaclassname obj) {
return obj.swigCPtr;
}
%}

11/12/2002: beazley
Fixed problem with abstract methods and signatures. For example:
class abstract_foo {
public:
virtual int meth(int meth_param) = 0;
};
class abstract_bar : public abstract_foo {
public:
int meth(int meth_param_1, int meth_param_2) { return 0; }
};
In this case, abstract_bar is still abstract.
Fixes [ 628438 ] Derived abstract class not abstract.
Reported and patched by Scott Michel.
11/11/2002: beazley
Fixed a matching problem with typemaps and array dimensions. For example, if you
had this:
typedef char blah[20];
and a typemap:
%typemap() char [ANY] {
... $1_dim0 ...
}
then $1_dim* variables weren't be expanded properly. It should work now.
Problem reported by Pankaj Kumar Goel.
11/07/2002: mkoeppe
Added an experimental new module that dumps SWIG's parse
tree as (Common) Lisp s-expressions. The module is
invoked with SWIG's -sexp command-line switch. The output
can be read into Common Lisp. There is (prototype)
example Lisp code that generates Foreign Function Interface
definitions for use with Kevin Rosenberg's UFFI.
*** EXPERIMENTAL NEW FEATURE ***
11/07/2002: mkoeppe
Removed duplicate declaration of "cpp_template_decl" in
parser.y; bison 1.75 complained.
11/06/2002: cheetah (William Fulton)
[Java] Default primitive array handling has changed like arrays of classes.
C primitive arrays are no longer wrapped by a Java array but with a pointer
(type wrapper class). Again the changes have been made for efficiency reasons.
The original typemaps have been moved into arrays_java.i, so the original
behaviour can be obtained merely including this file:
%include "arrays_java.i"
The array support functions are no longer generated by default. They are only
generated when including this file, thus this often unused code is only
generated when specifically requiring this type of array support.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
11/05/2002: ljohnson (Lyle Johnson)
[Ruby] Added support for nested module declarations (as was
previously added for the Perl module). So a %module directive
of the form:
%module "Outer::Inner::Foo"
will nest everything as (in Ruby code):
module Outer
module Inner
module Foo
# stuff goes here
end
end
end
11/05/2002: mkoeppe
[MzScheme] Add an argument (-declaremodule) that generates
code to correctly declare a primitive module extension.
Patch submitted by Bruce Butterfield.
11/02/2002: cheetah (William Fulton)
[Java] Added patch submitted by Michael Cahill to remove unused parameter
warnings for the jenv and cls parameters. This patch also also allows one
to use "void" in the jni typemap for any type without code being generated
attempting to return a value.
10/29/2002: cheetah (William Fulton)
[Java] Array handling is different. Arrays of classes are no longer wrapped
with proxy arrays, eg wrapping
class X {...};
X foo[10];
used to be wrapped with these Java getters and setters:
public static void setFoo(X[] value) {...}
public static X[] getFoo() {...}
This approach is very inefficient as the entire array is copied numerous
times on each invocation of the getter or setter. These arrays are now
wrapped with a pointer so it is only possible to access the first array element
using a proxy class:
public static void setFoo(X value) {...}
public static X getFoo() {...}
Arrays of enums have also been similarly changed. This behaviour is now like the
other SWIG language's implementation and the array library should be used to
access the other elements. The original behaviour can be achieved using the
macros and typemaps in arrays_java.i, for example:
%include "arrays_java.i"
JAVA_ARRAYSOFCLASSES(X)
class X {...};
X foo[10];
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
10/29/2002: cheetah (William Fulton)
[Java] Two new typemaps javain and javaout for generating the proxy class
and type wrapper class method calls to the JNI class. The new typemaps are
really used for transforming the jstype (used in proxy class and type wrapper
classes) to the jtype (used in the JNI class) and visa versa. A javain typemap
is required whenever an in typemap is written and similarly javaout for an out
typemap. An example is probably best to show them working:
%typemap(javain) Class "Class.getCPtr($javainput)"
%typemap(javain) unsigned short "$javainput"
%typemap(javaout) Class * {
return new Class($jnicall, $owner);
}
%inline %{
class Class {};
Class * bar(Class cls, unsigned short ush) { return new Class(); };
%}
The generated proxy code is then:
public static Class bar(Class cls, int ush) {
return new Class(exampleJNI.bar(Class.getCPtr(cls), ush), false);
}
Some new special variables have been introduced in order to use these typemaps.
Here $javainput has been replaced by 'cls' and 'ush'. $jnicall has been replaced by
the native method call, 'exampleJNI.bar(...)' and $owner has been replaced by 'false'.
$javainput is analogous to the $input special variable. It is replaced by the parameter name.
$jnicall is analogous to $action in %exception. It is replaced by the call to the native
method in the JNI class.
$owner is replaced by either true if %newobject has been used otherwise false.
The java.swg file contains default javain and javout typemaps which will produce the same code
as previously. This change is only of concern to those who have written their own typemaps as
you will then most likely have to write your own javain and javaout typemaps.
The javaout typemap also makes it possible to use a Java downcast to be used on abstract
proxy base classes. See the Java documentation on dynamic_cast.
