/*------------------------------------------------------------------------- * * windowapi.h * API for window functions to extract data from their window * * A window function does not receive its arguments in the normal way * (and therefore the concept of strictness is irrelevant). Instead it * receives a "WindowObject", which it can fetch with PG_WINDOW_OBJECT() * (note V1 calling convention must be used). Correct call context can * be tested with WindowObjectIsValid(). Although argument values are * not passed, the call is correctly set up so that PG_NARGS() can be * used and argument type information can be obtained with * get_fn_expr_argtype(), get_fn_expr_arg_stable(), etc. * * Operations on the WindowObject allow the window function to find out * the current row number, total number of rows in the partition, etc * and to evaluate its argument expression(s) at various rows in the * window partition. See the header comments for each WindowObject API * function in nodeWindowAgg.c for details. * * * Portions Copyright (c) 2000-2012, PostgreSQL Global Development Group * * src/include/windowapi.h * *------------------------------------------------------------------------- */ #ifndef WINDOWAPI_H #define WINDOWAPI_H /* values of "seektype" */ #define WINDOW_SEEK_CURRENT 0 #define WINDOW_SEEK_HEAD 1 #define WINDOW_SEEK_TAIL 2 /* this struct is private in nodeWindowAgg.c */ typedef struct WindowObjectData *WindowObject; #define PG_WINDOW_OBJECT() ((WindowObject) fcinfo->context) #define WindowObjectIsValid(winobj) \ ((winobj) != NULL && IsA(winobj, WindowObjectData)) extern void *WinGetPartitionLocalMemory(WindowObject winobj, Size sz); extern int64 WinGetCurrentPosition(WindowObject winobj); extern int64 WinGetPartitionRowCount(WindowObject winobj); extern void WinSetMarkPosition(WindowObject winobj, int64 markpos); extern bool WinRowsArePeers(WindowObject winobj, int64 pos1, int64 pos2); extern Datum WinGetFuncArgInPartition(WindowObject winobj, int argno, int relpos, int seektype, bool set_mark, bool *isnull, bool *isout); extern Datum WinGetFuncArgInFrame(WindowObject winobj, int argno, int relpos, int seektype, bool set_mark, bool *isnull, bool *isout); extern Datum WinGetFuncArgCurrent(WindowObject winobj, int argno, bool *isnull); #endif /* WINDOWAPI_H */
