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) { }
};

Determine whether this initializer is an implicit initializer generated for a field with an initializer defined on the member declaration.

In-class member initializers (also known as "non-static data member initializations", NSDMIs) were introduced in C++11.

◆ setSourceOrder()

void clang::CXXCtorInitializer::setSourceOrder ( int  Pos)
inline

Set the source order of this initializer.

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