Detailed Description

An expression that sends a message to the given Objective-C object or class.

The following contains two message send expressions:

[[NSString alloc] initWithString:@"Hello"]

The innermost message send invokes the "alloc" class method on the NSString class, while the outermost message send invokes the "initWithString" instance method on the object returned from NSString's "alloc". In all, an Objective-C message send can take on four different (although related) forms:

Send to an object instance.
Send to a class.
Send to the superclass instance of the current class.
Send to the superclass of the current class.

All four kinds of message sends are modeled by the ObjCMessageExpr class, and can be distinguished via getReceiverKind(). Example:

The "void *" trailing objects are actually ONE void * (the receiver pointer), and NumArgs Expr *. But due to the implementation of children(), these must be together contiguously.
