SWIG/directors dependency removal (cont'd) * Added to python/BPy_Convert.{cpp,h} 4 utility converters below for better introspection-based automatic type conversion. PyObject * Any_BPy_Interface0D_from_Interface0D( Interface0D& if0D ); PyObject * Any_BPy_Interface1D_from_Interface1D( Interface1D& if1D ); PyObject * Any_BPy_FEdge_from_FEdge( FEdge& fe ); PyObject * Any_BPy_ViewVertex_from_ViewVertex( ViewVertex& vv ); There are 4 corresponding converters without the "Any_" prefix. All calls of them in the code base were replaced with these new converters so that the introspection-based automatic conversion would take place universally. * python/BPy_Convert.{cpp,h}: Those C++ to Python converters having had a "_ptr" suffix were renamed to a name without the suffix, and their arguments were changed so as to take a reference (e.g., ViewVertex&) instead of a pointer (e.g., ViewVertex *). The changed converters and their new function prototypes are listed below. These converters now return a Python wrapper object that retains the passed reference, instead of retaining a newly created C++ object by the converters. // Interface0D converters PyObject * BPy_Interface0D_from_Interface0D( Interface0D& if0D ); PyObject * BPy_CurvePoint_from_CurvePoint( CurvePoint& cp ); PyObject * BPy_StrokeVertex_from_StrokeVertex( StrokeVertex& sv ); PyObject * BPy_SVertex_from_SVertex( SVertex& sv ); PyObject * BPy_ViewVertex_from_ViewVertex( ViewVertex& vv ); PyObject * BPy_TVertex_from_TVertex( TVertex& tv ); PyObject * BPy_NonTVertex_from_NonTVertex( NonTVertex& ntv ); // Interface1D converters PyObject * BPy_Interface1D_from_Interface1D( Interface1D& if1D ); PyObject * BPy_Chain_from_Chain( Chain& c ); PyObject * BPy_FEdge_from_FEdge( FEdge& fe ); PyObject * BPy_FEdgeSharp_from_FEdgeSharp( FEdgeSharp& fes ); PyObject * BPy_FEdgeSmooth_from_FEdgeSmooth( FEdgeSmooth& fes ); PyObject * BPy_Stroke_from_Stroke( Stroke& s ); PyObject * BPy_ViewEdge_from_ViewEdge( ViewEdge& ve ); PyObject * BPy_directedViewEdge_from_directedViewEdge( ViewVertex::directedViewEdge& dve ); // some other converters PyObject * BPy_ViewShape_from_ViewShape( ViewShape& vs ); PyObject * BPy_SShape_from_SShape( SShape& ss ); PyObject * BPy_FrsMaterial_from_FrsMaterial( FrsMaterial& m ); PyObject * BPy_StrokeAttribute_from_StrokeAttribute( StrokeAttribute& sa ); * Added a "borrowed" flag to the definitions of Python types being used to wrap C++ components of Freestyle's internal data structures. The flag indicates whether or not a Python wrapper object has a reference to a C++ object that comprises the internal data structures. The deallocation routines of the Python types check this flag and release a wrapped C++ object only when it is not part of the internal data structures. The following files were modified: python/BPy_FrsMaterial.{cpp,h} python/BPy_Interface0D.{cpp,h} python/BPy_Interface1D.{cpp,h} python/BPy_SShape.{cpp,h} python/BPy_StrokeAttribute.{cpp,h} python/BPy_ViewShape.{cpp,h} python/Interface0D/BPy_CurvePoint.cpp python/Interface0D/BPy_SVertex.cpp python/Interface0D/BPy_ViewVertex.cpp python/Interface0D/CurvePoint/BPy_StrokeVertex.cpp python/Interface0D/ViewVertex/BPy_NonTVertex.cpp python/Interface0D/ViewVertex/BPy_TVertex.cpp python/Interface1D/BPy_FEdge.cpp python/Interface1D/BPy_FrsCurve.cpp python/Interface1D/BPy_Stroke.cpp python/Interface1D/BPy_ViewEdge.cpp python/Interface1D/Curve/BPy_Chain.cpp python/Interface1D/FEdge/BPy_FEdgeSharp.cpp python/Interface1D/FEdge/BPy_FEdgeSmooth.cpp * view_map/Interface[01]D.h, python/BPy_Interface[01]D.cpp: Removed from the Interface0D and Interface1D C++ classes a back pointer to a Python wrapper object and all "director" calls. These classes (and their subclasses) are used to build Freestyle's main data structures (such as a view map and strokes) and their class hierarchy is static. Python wrappers of these C++ classes are only used to access the data structures from the Python layer, and not intended to extend the data structures by subclassing the Python wrappers. Without the necessity of subclassing in the Python layer, the back pointer to a wrapping Python object and "director" calls would be useless (actually they were not used at all), so they were all removed. * python/Director.{cpp,h}: Removed the definitions of directors that were no longer used. * stroke/Stroke.{cpp,h}: Removed an (unused) back pointer to a Python wrapper object. * python/BPy_ViewMap.cpp: Fixed a possible null pointer reference. * python/Interface1D/BPy_FEdge.cpp: Fixed parameter checking in FEdge___init__().
