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.
Notes
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.
