Overview

Represents a set of child diagnostics from a parent Diagnostic.

This is not an AutoPointer because the CXDiagnosticSet pointer is owned by the parent Diagnostic. Per the libclang docs: “This CXDiagnosticSet does not need to be released by clang_disposeDiagnosticSet.”

Individual diagnostics obtained from the set DO need disposal via clang_disposeDiagnostic, which is handled by the Diagnostic AutoPointer. Diagnostics are cached on construction so that repeated iteration does not create duplicate AutoPointers that would double-free.
