◆ RealizedClassGenerationCountChanged()

bool AppleObjCRuntimeV2::RealizedClassGenerationCountChanged ( )

private

Update the generation count of realized classes.

This is not an exact count but rather a value that is incremented when new classes are realized or destroyed. Unlike the count in gdb_objc_realized_classes, it will change when lazily named classes get realized.
