| <h3 class="section">8.10 Method Modifiers (<code>const</code>, <code>volatile</code>, <code>const volatile</code>)</h3> |
| |
| <p><< based on a6.C >> |
| |
| <p>In the class example described above all the methods have the normal |
| modifier. This method modifier information is located just after the |
| protection information for the method. This field has four possible |
| character values. Normal methods use ‘<samp><span class="samp">A</span></samp>’, const methods use |
| ‘<samp><span class="samp">B</span></samp>’, volatile methods use ‘<samp><span class="samp">C</span></samp>’, and const volatile methods use |
| ‘<samp><span class="samp">D</span></samp>’. Consider the class definition below: |
| |
| <pre class="example"> class A { |
| public: |
| int ConstMeth (int arg) const { return arg; }; |
| char VolatileMeth (char arg) volatile { return arg; }; |
| float ConstVolMeth (float arg) const volatile {return arg; }; |
| }; |
| </pre> |
| <p>This class is described by the following stab: |
| |
| <pre class="display"> .stabs "class(A):sym_desc(struct)type_def(20)=type_desc(struct)struct_bytes(1) |
| meth_name(ConstMeth)::type_def(21)sym_desc(method) |
| returning(int);:arg(int);protection(public)modifier(const)virtual(no); |
| meth_name(VolatileMeth)::type_def(22)=sym_desc(method) |
| returning(char);:arg(char);protection(public)modifier(volatile)virt(no) |
| meth_name(ConstVolMeth)::type_def(23)=sym_desc(method) |
| returning(float);:arg(float);protection(public)modifier(const volatile) |
| virtual(no);;", <small class="dots">...</small> |
| </pre> |
| <pre class="example"> .stabs "A:T20=s1ConstMeth::21=##1;:i;2B.;VolatileMeth::22=##2;:c;2C.; |
| ConstVolMeth::23=##12;:f;2D.;;",128,0,0,0 |
| </pre> |
