VectorInt.Shift Method (TMtxVecInt, integer, integer, integer, integer)

A shift on vector elements in range.

Pascal

function Shift(const Src: TMtxVecInt; const Offset: integer; const SrcIndex: integer; const Index: integer; const Len: integer): TMtxVecInt; overload;

Description

Performs a shift on source vector elements in specified range [SrcIndex .. SrcIndex+Len-1] and stores them to calling vector elements [Index .. Index+Len-1]. The number of elements to shift is specified in the Offset parameter. Offset can be any integer number, positive or negative.

An exception is raised if array borders are overrun/underrun.
