Assigns a value to a key in the table, without invoking metamethods.

table = rawset (table, index, value)

Arguments

table

table - any valid table.

index

non-nil - any valid table index.

value

any - any value.

Returns

table

table - the table you passed as the first parameter.

Example

mytable = { }
rawset(mytable, "version", 1.0)

Details

• Sets the real value of table[index] to value, without invoking any metamethod. table must be a table, index any value different from nil, and value any Lua value.
• Metamethods can be used to change the way LUA works with certain variables. For example you could change what LUA does if you set a tables index to a new value. By using rawset you can set an index without invoking these methods, which is primarily usefull in the metamethod that actually sets the tables index to value, otherwise this metamethod would invoke itself over and over again.
