struct DynamicTagObserver

This is the base class for Dynamic*Observer classes.

Each Observer subclass should define these two methods:

* template

<class

DiagnosticsType, class Memory>

bool Observe(DiagnosticsType

&

diagnostics, Memory

&

memory,

DynamicTagMatch

<Tag

> tag, Addr val);

* template

<class

DiagnosticsType, class Memory>

bool Finish(DiagnosticsType

&

diagnostics, Memory

&

memory);

Observe will be called with each entry matching any Tag of the Tags... list.

Then Finish will be called at the end of all entries unless processing was

terminated early for some reason, in which case the observer object is

usually going to be destroyed without checking its results. Both return

false if processing the dynamic section should be terminated early.
