space_object:frommap()

object space_object

space_object:frommap(map[, option])

Convert a map to a tuple instance or to a table. The map must consist of “field name = value” pairs. The field names and the value types must match names and types stated previously for the space, via space_object:format().

Parameters:	space_object (space_object) – an object reference map (field-value-pairs) – a series of “field = value” pairs, in any order. option (boolean) – the only legal option is {table = true|false}; if the option is omitted or if {table = false}, then return type will be ‘cdata’ (i.e. tuple); if {table = true}, then return type will be ‘table’.
Return:	a tuple instance or table.
Rtype:	tuple or table

Possible errors: space_object does not exist or has no format; “unknown field”.

Example:

-- Create a format with two fields named 'a' and 'b'.
-- Create a space with that format.
-- Create a tuple based on a map consistent with that space.
-- Create a table based on a map consistent with that space.
