From 730fb1021c8b189229625866dac0f6e83db6418c Mon Sep 17 00:00:00 2001 From: Tamito Kajiyama Date: Sun, 26 Jul 2009 16:15:28 +0000 Subject: Made predicate and function types callable in the sense that callable(I, T) returns True when I is an object of a type T or of a subtype of T. Also implemented a measure to avoid an infinite loop when user-defined predicate and function classes do not properly overload the __call__ method (including the cases of directly instantiating the base classes such as UnaryPredicate0D and BinaryPredicate1D). --- .../python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) (limited to 'source/blender/freestyle/intern/python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp') diff --git a/source/blender/freestyle/intern/python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp b/source/blender/freestyle/intern/python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp index 1dd24b1fbb7..89d79e0b83f 100644 --- a/source/blender/freestyle/intern/python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp +++ b/source/blender/freestyle/intern/python/UnaryFunction1D/BPy_UnaryFunction1DDouble.cpp @@ -32,14 +32,13 @@ static void UnaryFunction1DDouble___dealloc__(BPy_UnaryFunction1DDouble* self); static PyObject * UnaryFunction1DDouble___repr__(BPy_UnaryFunction1DDouble* self); static PyObject * UnaryFunction1DDouble_getName( BPy_UnaryFunction1DDouble *self); -static PyObject * UnaryFunction1DDouble___call__( BPy_UnaryFunction1DDouble *self, PyObject *args); +static PyObject * UnaryFunction1DDouble___call__( BPy_UnaryFunction1DDouble *self, PyObject *args, PyObject *kwds); static PyObject * UnaryFunction1DDouble_setIntegrationType(BPy_UnaryFunction1DDouble* self, PyObject *args); static PyObject * UnaryFunction1DDouble_getIntegrationType(BPy_UnaryFunction1DDouble* self); /*----------------------UnaryFunction1DDouble instance definitions ----------------------------*/ static PyMethodDef BPy_UnaryFunction1DDouble_methods[] = { {"getName", ( PyCFunction ) UnaryFunction1DDouble_getName, METH_NOARGS, "（ ）Returns the string of the name of the unary 1D function."}, - {"__call__", ( PyCFunction ) UnaryFunction1DDouble___call__, METH_VARARGS, "（Interface1D if1D ）Builds a UnaryFunction1D from an integration type.
