Expand description
Kinds of metamethods that can be overridden.
Currently, this mechanism does not allow overriding the __gc
metamethod, since there is
generally no need to do so: UserData
implementors can instead just implement Drop
.
Variants
Add
The +
operator.
Sub
The -
operator.
Mul
The *
operator.
Div
The /
operator.
Mod
The %
operator.
Pow
The ^
operator.
Unm
The unary minus (-
) operator.
IDiv
The floor division (//) operator.
Requires feature = "lua54/lua53"
BAnd
The bitwise AND (&) operator.
Requires feature = "lua54/lua53"
BOr
The bitwise OR (|) operator.
Requires feature = "lua54/lua53"
BXor
The bitwise XOR (binary ~) operator.
Requires feature = "lua54/lua53"
BNot
The bitwise NOT (unary ~) operator.
Requires feature = "lua54/lua53"
Shl
The bitwise left shift (<<) operator.
Shr
The bitwise right shift (>>) operator.
Concat
The string concatenation operator ..
.
Len
The length operator #
.
Eq
The ==
operator.
Lt
The <
operator.
Le
The <=
operator.
Index
Index access obj[key]
.
NewIndex
Index write access obj[key] = value
.
Call
The call “operator” obj(arg1, args2, ...)
.
ToString
The __tostring
metamethod.
This is not an operator, but will be called by methods such as tostring
and print
.
Pairs
The __pairs
metamethod.
This is not an operator, but it will be called by the built-in pairs
function.
Requires feature = "lua54/lua53/lua52"
IPairs
The __ipairs
metamethod.
This is not an operator, but it will be called by the built-in ipairs
function.
Requires feature = "lua52"
Close
The __close
metamethod.
Executed when a variable, that marked as to-be-closed, goes out of scope.
More information about to-be-closed variabled can be found in the Lua 5.4 documentation.
Requires feature = "lua54"
Custom(StdString)
A custom metamethod.
Must not be in the protected list: __gc
, __metatable
, __mlua*
.
