Constructor Details

RespCommand

protected RespCommand(int arity,
 int firstKeyPos,
 int lastKeyPos,
 int steps)

Parameters:

arity - the number of arguments

firstKeyPos - the position of the command's first key name argument. For most commands, the first key's position is 1. Position 0 is always the command name itself.

lastKeyPos - the position of the command's last key name argument. Redis commands usually accept one, two or multiple number of keys. Commands that accept a single key have both first key and last key set to 1. Commands that accept two key name arguments, e.g. BRPOPLPUSH, SMOVE and RENAME, have this value set to the position of their second key. Multi-key commands that accept an arbitrary number of keys, such as MSET, use the value -1.

steps - the step, or increment, between the first key and the position of the next key.

RespCommand

protected RespCommand(String name,
 int arity,
 int firstKeyPos,
 int lastKeyPos,
 int steps)

Parameters:

name - the name of the command

arity - the number of arguments

firstKeyPos - the position of the command's first key name argument. For most commands, the first key's position is 1. Position 0 is always the command name itself.

lastKeyPos - the position of the command's last key name argument. Redis commands usually accept one, two or multiple number of keys. Commands that accept a single key have both first key and last key set to 1. Commands that accept two key name arguments, e.g. BRPOPLPUSH, SMOVE and RENAME, have this value set to the position of their second key. Multi-key commands that accept an arbitrary number of keys, such as MSET, use the value -1.

steps - the step, or increment, between the first key and the position of the next key.
