メタテーブル、メタフィールド、および名前呼び出しメソッド。 ## 利用できる関数 Returns a raw metafield value from the target metatable. target may be any value, and field must be a string. The function does not call the metafield, does not invoke \_\_index lookup, and returns nil when the metatable or field is missing. the current namecall method に保存されている current Luau namecall atom を返します。この function は arguments を取らず、exactly one value を返します。the current namecall method が存在し、the current namecall method が 0 より大きく、the current namecall method が non-null の場合、その data を string return で string として push します。それ以外の場合は nil を push します。function は arguments を検査せず、target object から method name を計算せず、metamethod を呼び出しません。get\_namecall\_method は getnamecallmethod の alias です。 Returns the metatable currently attached to a target value, or nil when none is present. The function returns exactly one value and does not change the target. debug.getmethods is an alias for getrawmethods. Returns whether the target value has a non-nil raw metafield with the requested name. The function does not call the metafield, does not invoke \_\_index lookup, and does not change readonly state. Returns whether the target value has a metatable. The function returns one boolean and does not return or change the metatable itself. Returns whether a table is readonly. The argument must be a table, and the function does not change it. Marks a table as readonly and returns no values. Marks a table as writable and returns no values. Replaces the current namecall method string when a current namecall method exists. The method argument must be a string. If no current namecall method exists, the call returns no values and does not create one. set\_namecall\_method is an alias. Sets the metatable for a target value and returns the original target. metatable must be a table or nil; nil clears the metatable. debug.setmethods is an alias for setrawmethods. Sets whether a table is readonly and returns no values.
