<p>Creates a new <aclass="el"href="classcrashpad_1_1MemorySnapshot.html"title="An abstract interface to a snapshot representing a region of memory present in a snapshot process...">MemorySnapshot</a> based on merging this one with <em>other</em>. </p>
<p>The ranges described by the two snapshots must either overlap or abut, and must be of the same concrete type.</p>
<dlclass="section return"><dt>Returns</dt><dd>A newly allocated <aclass="el"href="classcrashpad_1_1MemorySnapshot.html"title="An abstract interface to a snapshot representing a region of memory present in a snapshot process...">MemorySnapshot</a> representing the merged range, or <code>nullptr</code> with an error logged. </dd></dl>

<p>Implementations do not necessarily read the memory snapshot data prior to this method being called. Memory snapshot data may be loaded lazily and may be discarded after being passed to the delegate. This provides clean memory management without burdening a snapshot implementation with the requirement that it track all memory region data simultaneously.</p>
