ShiftCommand1

ShiftCommand1 is a labeled command used in software documentation and codebases to denote the first variant of a shift operation. It is not a standard or widely defined primitive; its exact behavior depends on the surrounding system. In many implementations, ShiftCommand1 is associated with moving elements by a single unit, such as shifting a value or position one step in a sequence.

In practice, ShiftCommand1 is often implemented using the Command design pattern, encapsulating the action and its parameters (direction, wrap, amount). The numeral suggests either the magnitude (one unit) or the variant index within a family of related commands, such as ShiftCommand1, ShiftCommand2, etc.

Common contexts include data processing, buffers, cyclic structures, text editors, and robotics state machines. For example, if applied to an array [A,B,C,D] with left shift and wrap enabled, it yields [B,C,D,A]. The exact semantics and the effect of ShiftCommand1 can vary by platform and project.

Limitations and related concepts: the behavior of ShiftCommand1 is not standardized across systems, and implementations may differ in direction options, wrap behavior, or interaction with other commands. Users should consult the specific project or library documentation to understand how ShiftCommand1 is defined in that context. Related concepts include general shift or rotate operations, the Command design pattern, and the broader family of ShiftCommand variants (such as ShiftCommand2, ShiftCommand3) used to represent larger offsets or alternate semantics.
