overridevirtual

Set member variables when a block insertion occurs.

Resets reference count to 1 (the insertion counts as a reference), and touch block if it hadn't been touched previously. Sets the insertion tick to the current tick. Marks the block valid.

Parameters

tag	Block address tag.
is_secure	Whether the block is in secure space or not.
src_requestor_ID	The source requestor ID.
task_ID	The new task ID.
