Class: (global)

Description

Returns three values: an iterator function, the table t, and 0, so that the construction

  for i,v in ipairs(t) do body end

will iterate over the pairs (1,t[1]), (2,t[2]), ···, up to the first integer key absent from the table.

(function), (table), (any) = ipairs(t)

Parameters

t: (table) indexed table to iterate through

Return values

Returns (function) iterator function
Returns (table) provided table t
Returns (any) value 0
