/* ----------------------------------------------------------------------------- * arrays_javascript.i * * These typemaps give more natural support for arrays. The typemaps are not efficient * as there is a lot of copying of the array values whenever the array is passed to C/C++ * from JavaScript and vice versa. The JavaScript array is expected to be the same size as the C array. * An exception is thrown if they are not. * * Example usage: * Wrapping: * * %include * %inline %{ * extern int FiddleSticks[3]; * %} * * Use from JavaScript like this: * * var fs = [10, 11, 12]; * example.FiddleSticks = fs; * fs = example.FiddleSticks; * ----------------------------------------------------------------------------- */ %fragment("SWIG_JSCGetIntProperty", "header", fragment=SWIG_AsVal_frag(int)) {} %fragment("SWIG_JSCGetNumberProperty", "header", fragment=SWIG_AsVal_frag(double)) {} %typemap(in, fragment="SWIG_JSCGetIntProperty") int[], int[ANY] (int length = 0, v8::Local array, v8::Local jsvalue, int i = 0, int res = 0, $*1_ltype temp) { if ($input->IsArray()) { // Convert into Array array = v8::Local::Cast($input); length = $1_dim0; $1 = ($*1_ltype *)malloc(sizeof($*1_ltype) * length); // Get each element from array for (i = 0; i < length; i++) { jsvalue = array->Get(i); // Get primitive value from JSObject res = SWIG_AsVal(int)(jsvalue, &temp); if (!SWIG_IsOK(res)) { SWIG_exception_fail(SWIG_ERROR, "Failed to convert $input to double"); } arg$argnum[i] = temp; } } else { SWIG_exception_fail(SWIG_ERROR, "$input is not JSObjectRef"); } } %typemap(freearg) int[], int[ANY] { free($1); } %typemap(out, fragment=SWIG_From_frag(int)) int[], int[ANY] (int length = 0, int i = 0) { length = $1_dim0; v8::Local array = v8::Array::New(length); for (i = 0; i < length; i++) { array->Set(i, SWIG_From(int)($1[i])); } $result = array; } %typemap(in, fragment="SWIG_JSCGetNumberProperty") double[], double[ANY] (int length = 0, v8::Local array, v8::Local jsvalue, int i = 0, int res = 0, $*1_ltype temp) { if ($input->IsArray()) { // Convert into Array array = v8::Local::Cast($input); length = $1_dim0; $1 = ($*1_ltype *)malloc(sizeof($*1_ltype) * length); // Get each element from array for (i = 0; i < length; i++) { jsvalue = array->Get(i); // Get primitive value from JSObject res = SWIG_AsVal(double)(jsvalue, &temp); if (!SWIG_IsOK(res)) { SWIG_exception_fail(SWIG_ERROR, "Failed to convert $input to double"); } arg$argnum[i] = temp; } } else { SWIG_exception_fail(SWIG_ERROR, "$input is not JSObjectRef"); } } %typemap(freearg) double[], double[ANY] { free($1); } %typemap(out, fragment=SWIG_From_frag(double)) double[], double[ANY] (int length = 0, int i = 0) { length = $1_dim0; v8::Local array = v8::Array::New(length); for (i = 0; i < length; i++) { array->Set(i, SWIG_From(double)($1[i])); } $result = array; }
