Detailed Description

Represents a C++ base or member initializer.

This is part of a constructor initializer that initializes one non-static member variable or one base class. For example, in the following, both 'A(a)' and 'f(3.14159)' are member initializers:

 class A { };
 class B : public A {
   float f;
 public:
   B(A& a) : A(a), f(3.14159) { }
 };

This can only be called once for each initializer; it cannot be called on an initializer having a positive number of (implicit) array indices.

This assumes that the initialzier was written in the source code, and ensures that isWritten() returns true.
