Check for classes that accept 'objectForKey:' (or the other selectors that the migrator handles) but return their instances as 'id', resulting in the compiler resolving 'objectForKey:' as the method from NSDictionary.

getLiteralInfo()

getNSArrayObjects()

If Msg is an NSArray creation message or literal, this gets the objects that were used to create it.

Returns

true if it is an NSArray and we got objects, or false otherwise.

maybeAdjustInterfaceForSubscriptingCheck()

Check for classes that accept 'objectForKey:' (or the other selectors that the migrator handles) but return their instances as 'id', resulting in the compiler resolving 'objectForKey:' as the method from NSDictionary.

When checking if we can convert to subscripting syntax, check whether the receiver is a result of a class method from a hardcoded list of such classes. In such a case return the specific class as the interface of the receiver.

FIXME: Remove this when these classes start using 'instancetype'.

shouldNotRewriteImmediateMessageArgs()

Returns true if the immediate message arguments of Msg should not be rewritten because it will interfere with the rewrite of the parent message expression.

e.g.

[NSDictionary dictionaryWithObjects:

[NSArray arrayWithObjects:@"1", @"2", nil]

forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];

It will return true for this because we are going to rewrite this directly to a dictionary literal without any array literals.
