Detailed Description

CallExpr - Represents a function call (C99 6.5.2.2, C++ [expr.call]).

CallExpr itself represents a normal function call, e.g., "f(x, 2)", while its subclasses may represent alternative syntax that (semantically) results in a function call. For example, CXXOperatorCallExpr is a subclass for overloaded operator calls that use operator syntax, e.g., "str1 + str2" to resolve to a function call.

ArrayRef<Stmt*> clang::CallExpr::getRawSubExprs ( )

This method provides fast access to all the subexpressions of a CallExpr without going through the slower virtual child_iterator interface.

This provides efficient reverse iteration of the subexpressions. This is currently used for CFG construction.
