+INPUT typemaps
+--------------
+
+These typemaps remap a C pointer or C++ reference to be an "INPUT" value which is
+passed by value instead of reference.
+
+The following typemaps can be applied to turn a pointer or reference into a simple
+input value. That is, instead of passing a pointer or reference to an object,
+you would use a real value instead.
+
+ bool *INPUT, bool &INPUT
+ signed char *INPUT, signed char &INPUT
+ unsigned char *INPUT, unsigned char &INPUT
+ short *INPUT, short &INPUT
+ unsigned short *INPUT, unsigned short &INPUT
+ int *INPUT, int &INPUT
+ unsigned int *INPUT, unsigned int &INPUT
+ long *INPUT, long &INPUT
+ unsigned long *INPUT, unsigned long &INPUT
+ long long *INPUT, long long &INPUT
+ unsigned long long *INPUT, unsigned long long &INPUT
+ float *INPUT, float &INPUT
+ double *INPUT, double &INPUT
+
+To use these, suppose you had a C function like this :
+
+ double fadd(double *a, double *b) {
+ return *a+*b;
+ }
+
+You could wrap it with SWIG as follows :
+
+ %include <typemaps.i>
+ double fadd(double *INPUT, double *INPUT);
+
+or you can use the %apply directive :
+
+ %include <typemaps.i>
+ %apply double *INPUT { double *a, double *b };
+ double fadd(double *a, double *b);
+
+In Java you could then use it like this:
+ double answer = modulename.fadd(10.0, 20.0);
+
+There are no char *INPUT typemaps, however you can apply the signed char * typemaps instead:
+ %include <typemaps.i>
+ %apply signed char *INPUT {char *input};
+ void f(char *input);

+OUTPUT typemaps
+---------------
+
+The following typemaps can be applied to turn a pointer or reference into an "output"
+value. When calling a function, no input value would be given for
+a parameter, but an output value would be returned. This works by a
+Java array being passed as a parameter where a c pointer or reference is required.
+As with any Java function, the array is passed by reference so that
+any modifications to the array will be picked up in the calling function.
+Note that the array passed in MUST have at least one element, but as the
+c function does not require any input, the value can be set to anything.
+
+ bool *OUTPUT, bool &OUTPUT
+ signed char *OUTPUT, signed char &OUTPUT
+ unsigned char *OUTPUT, unsigned char &OUTPUT
+ short *OUTPUT, short &OUTPUT
+ unsigned short *OUTPUT, unsigned short &OUTPUT
+ int *OUTPUT, int &OUTPUT
+ unsigned int *OUTPUT, unsigned int &OUTPUT
+ long *OUTPUT, long &OUTPUT
+ unsigned long *OUTPUT, unsigned long &OUTPUT
+ long long *OUTPUT, long long &OUTPUT
+ unsigned long long *OUTPUT, unsigned long long &OUTPUT
+ float *OUTPUT, float &OUTPUT
+ double *OUTPUT, double &OUTPUT
+
+For example, suppose you were trying to wrap the modf() function in the
+C math library which splits x into integral and fractional parts (and
+returns the integer part in one of its parameters):
+
+ double modf(double x, double *ip);
+
+You could wrap it with SWIG as follows :
+
+ %include <typemaps.i>
+ double modf(double x, double *OUTPUT);
+
+or you can use the %apply directive :
+
+ %include <typemaps.i>
+ %apply double *OUTPUT { double *ip };
+ double modf(double x, double *ip);
+
+The Java output of the function would be the function return value and the
+value in the single element array. In Java you would use it like this:
+
+ double[] ptr = {0.0};
+ double fraction = modulename.modf(5.0,ptr);
+
+There are no char *OUTPUT typemaps, however you can apply the signed char * typemaps instead:
+ %include <typemaps.i>
+ %apply signed char *OUTPUT {char *output};
+ void f(char *output);

+INOUT typemaps
+--------------
+
+Mappings for a parameter that is both an input and an output parameter
+
+The following typemaps can be applied to make a function parameter both
+an input and output value. This combines the behavior of both the
+"INPUT" and "OUTPUT" typemaps described earlier. Output values are
+returned as an element in a Java array.
+
+ bool *INOUT, bool &INOUT
+ signed char *INOUT, signed char &INOUT
+ unsigned char *INOUT, unsigned char &INOUT
+ short *INOUT, short &INOUT
+ unsigned short *INOUT, unsigned short &INOUT
+ int *INOUT, int &INOUT
+ unsigned int *INOUT, unsigned int &INOUT
+ long *INOUT, long &INOUT
+ unsigned long *INOUT, unsigned long &INOUT
+ long long *INOUT, long long &INOUT
+ unsigned long long *INOUT, unsigned long long &INOUT
+ float *INOUT, float &INOUT
+ double *INOUT, double &INOUT
+
+For example, suppose you were trying to wrap the following function :
+
+ void neg(double *x) {
+ *x = -(*x);
+ }
+
+You could wrap it with SWIG as follows :
+
+ %include <typemaps.i>
+ void neg(double *INOUT);
+
+or you can use the %apply directive :
+
+ %include <typemaps.i>
+ %apply double *INOUT { double *x };
+ void neg(double *x);
+
+This works similarly to C in that the mapping directly modifies the
+input value - the input must be an array with a minimum of one element.
+The element in the array is the input and the output is the element in
+the array.
+
+ double x[] = {5.0};
+ neg(x);
+
+The implementation of the OUTPUT and INOUT typemaps is different to other
+languages in that other languages will return the output value as part
+of the function return value. This difference is due to Java being a typed language.
+
+There are no char *INOUT typemaps, however you can apply the signed char * typemaps instead:
+ %include <typemaps.i>
+ %apply signed char *INOUT {char *inout};
+ void f(char *inout);
