Detailed Description

Store the information needed for fancy-indexing over an array. The fields are slightly unordered to keep consec, dataptr and subspace where they were originally.

Field Documentation

PyArrayIterObject* PyArrayMapIterObject::ait

Flat iterator for the indexed array. For compatibility solely.

PyArrayObject* PyArrayMapIterObject::array

char* PyArrayMapIterObject::baseoffset

pointer when all fancy indices are 0

int PyArrayMapIterObject::consec

after binding consec denotes at which axis the fancy axes are inserted.

npy_intp PyArrayMapIterObject::dimensions[NPY_MAXDIMS]

dimensions

PyArrayObject* PyArrayMapIterObject::extra_op

Extra op information.

PyArray_Descr* PyArrayMapIterObject::extra_op_dtype

desired dtype

npy_uint32* PyArrayMapIterObject::extra_op_flags

Iterator flags

NpyIter* PyArrayMapIterObject::extra_op_iter

NpyIter_IterNextFunc* PyArrayMapIterObject::extra_op_next

char** PyArrayMapIterObject::extra_op_ptrs

npy_intp PyArrayMapIterObject::fancy_dims[NPY_MAXDIMS]

npy_intp PyArrayMapIterObject::fancy_strides[NPY_MAXDIMS]

npy_intp PyArrayMapIterObject::index

current index

npy_intp PyArrayMapIterObject::iter_count

Count for the external loop (which ever it is) for API iteration

int PyArrayMapIterObject::iteraxes[NPY_MAXDIMS]

if subspace iteration, then this is the array of axes in the underlying array represented by the index objects

int PyArrayMapIterObject::nd

number of dims

Referenced by array_length(), and PyUFunc_FromFuncAndDataAndSignature().

int PyArrayMapIterObject::nd_fancy

int PyArrayMapIterObject::needs_api

Whether the iterator (any of the iterators) requires API

PyObject_HEAD int PyArrayMapIterObject::numiter

Multi-iterator portion --- needs to be present in this order to work with PyArray_Broadcast

number of index-array

iterators

NpyIter* PyArrayMapIterObject::outer

index objects

iterator

NpyIter_IterNextFunc* PyArrayMapIterObject::outer_next

Information about the iteration state.

char** PyArrayMapIterObject::outer_ptrs

npy_intp* PyArrayMapIterObject::outer_strides

npy_intp PyArrayMapIterObject::size

size of broadcasted

result

PyArrayObject* PyArrayMapIterObject::subspace

Subspace array. For binary compatibility (was an iterator, but only the check for NULL should be used).

Referenced by PyUFunc_FromFuncAndDataAndSignature().

NpyIter* PyArrayMapIterObject::subspace_iter

Information about the subspace iterator.

NpyIter_IterNextFunc* PyArrayMapIterObject::subspace_next
