PyArray_ArgFunc* PyArray_ArrFuncs::argmax

Function to select largest Can be NULL

Referenced by PyArray_ArgMax().

PyArray_ArgSortFunc* PyArray_ArrFuncs::argsort[NPY_NSORTS]

int** PyArray_ArrFuncs::cancastscalarkindto

int* PyArray_ArrFuncs::cancastto

Referenced by PyArray_RegisterCanCast().

PyArray_VectorUnaryFunc* PyArray_ArrFuncs::cast[NPY_NTYPES_ABI_COMPATIBLE]

Functions to cast to most other standard types Can have some NULL entries. The types DATETIME, TIMEDELTA, and HALF go into the castdict even though they are built-in.

Referenced by PyArray_InitArrFuncs().

PyObject* PyArray_ArrFuncs::castdict

Dictionary of additional casting functions PyArray_VectorUnaryFuncs which can be populated to support casting to other registered types. Can be NULL

Referenced by PyArray_GetCastFunc(), and PyArray_RegisterCastFunc().

PyArray_CompareFunc* PyArray_ArrFuncs::compare

Function to compare items Can be NULL

PyArray_CopySwapFunc* PyArray_ArrFuncs::copyswap

PyArray_CopySwapNFunc* PyArray_ArrFuncs::copyswapn

Copy and/or swap data. Memory areas may not overlap Use memmove first if they might

Referenced by _copyswap().

PyArray_DotFunc* PyArray_ArrFuncs::dotfunc

Function to compute dot product Can be NULL

PyArray_FastClipFunc* PyArray_ArrFuncs::fastclip

Referenced by PyArray_Clip().

PyArray_FastPutmaskFunc* PyArray_ArrFuncs::fastputmask

PyArray_FastTakeFunc* PyArray_ArrFuncs::fasttake

PyArray_FillFunc* PyArray_ArrFuncs::fill

Used for arange. Can be NULL.

PyArray_FillWithScalarFunc* PyArray_ArrFuncs::fillwithscalar

Function to fill arrays with scalar values Can be NULL

PyArray_FromStrFunc* PyArray_ArrFuncs::fromstr

Function to read a single value from a string and adjust the pointer; Can be NULL

Referenced by fromstr_next_element().

PyArray_GetItemFunc* PyArray_ArrFuncs::getitem

The next four functions cannot be NULL

Functions to get and set items with standard Python types -- not array scalars

Referenced by array_float(), array_hex(), and array_int().

PyArray_NonzeroFunc* PyArray_ArrFuncs::nonzero

Function to determine if data is zero or not If NULL a default version is used at Registration time.

PyArray_ScalarKindFunc* PyArray_ArrFuncs::scalarkind

Functions useful for generalizing the casting rules. Can be NULL;

Referenced by _signbit_set().

PyArray_ScanFunc* PyArray_ArrFuncs::scanfunc

Function to scan an ASCII file and place a single value plus possible separator Can be NULL

Referenced by fromfile_next_element(), and PyArray_Arange().

PyArray_SetItemFunc* PyArray_ArrFuncs::setitem

PyArray_SortFunc* PyArray_ArrFuncs::sort[NPY_NSORTS]

Sorting functions Can be NULL
