NAME
|
|
decltype
|
|
|
|
SYNTAX
|
|
decltype(<expr>)
|
|
|
|
DESCRIPTION
|
|
The expression will compiled just to determine the resulting type.
|
|
The expression itself will not be executed. The result of this
|
|
operator is the lpctype value representing the expression result.
|
|
|
|
NOTE
|
|
The result of this operator depends on a lot of factors, for example
|
|
if any type information is preserved for any inherited programs that
|
|
are referenced in the expression. But it also depends on the type
|
|
inference capabilities of the LPC compiler. So future versions of
|
|
LDMud might have different results on the same expression.
|
|
|
|
|
|
EXAMPLES
|
|
int var;
|
|
decltype(var) /* result: [int] */
|
|
|
|
string fun();
|
|
decltype(fun()) /* result: [string], fun() will not be called. */
|
|
|
|
HISTORY
|
|
Introduced in LDMud 3.6.7.
