Detailed Description
Represents a C++ pseudo-destructor (C++ [expr.pseudo]).
A pseudo-destructor is an expression that looks like a member access to a destructor of a scalar type, except that scalar types don't have destructors. For example:
typedef int T; void f(int *p) { p->T::~T(); }
Pseudo-destructors typically occur when instantiating templates such as:
template<typename T> void destroy(T* ptr) { ptr->T::~T(); }
for scalar types. A pseudo-destructor expression has no run-time semantics beyond evaluating the base expression.

Retrieve the source location information for the type being destroyed.
This type-source information is available for non-dependent pseudo-destructor expressions and some dependent pseudo-destructor expressions. Returns NULL if we only have the identifier for a dependent pseudo-destructor expression.

| TypeSourceInfo* clang::CXXPseudoDestructorExpr::getScopeTypeInfo | ( | ) | const [inline] |
Retrieve the scope type in a qualified pseudo-destructor expression.
Pseudo-destructor expressions can have extra qualification within them that is not part of the nested-name-specifier, e.g., p->T::~T(). Here, if the object type of the expression is (or may be) a scalar type, T may also be a scalar type and, therefore, cannot be part of a nested-name-specifier. It is stored as the "scope type" of the pseudo- destructor expression.
| SourceRange CXXPseudoDestructorExpr::getSourceRange | ( | ) | const |
SourceLocation tokens are not useful in isolation - they are low level value objects created/interpreted by SourceManager. We assume AST clients will have a pointer to the respective SourceManager.
