Delete the old ones in package kotlin.reflect.jvm because otherwise the code using those functions will become red in a lot less meaningful way (overload resolution ambiguity) than if they're deleted (unresolved import) Based on the work originally done by @dnpetrov #KT-8380 Fixed
Several directives can be added in the beginning of a test file in the syntax:
// !DIRECTIVE
Directives:
1. DIAGNOSTICS
Must be
'([ + - ! ] DIAGNOSTIC_FACTORY_NAME | ERROR | WARNING | INFO ) +'
where
-
'+'means 'include'; -
'-'means 'exclude'; -
'!'means 'exclude everything but this'.Directives are applied in the order of appearance, i.e.
!FOO +BARmeans include onlyFOOandBAR.
Examples:
// !DIAGNOSTICS: -WARNING +CAST_NEVER_SUCCEEDS
// !DIAGNOSTICS: -UNUSED_EXPRESSION -UNUSED_PARAMETER -UNUSED_VARIABLE
2. CHECK_TYPE
The directive adds the following declarations to the file:
class _<T>
fun <T> T.checkType(f: (_<T>) -> Unit) = f
With that, an exact type of an expression can be checked in the following way:
fun test(expr: A) {
expr checkType { it: _<A> }
}
Usage:
// !CHECK_TYPE
3. FILE
The directive let you compose a test consisting of several files in one actual file.
Usage:
// FILE: A.java /* Java code */
// FILE: B.kt /* kotlin code */
