Purpose

It ensures that new price values propagated from the Oracles are not taken up by the system until a specified delay has passed.

Key Responsibilities

• Periodically feeds a delayed price into the system for a particular collateral type.

Key Methods

• peek() Returns the current feed value and a boolean indicating whether it is valid.

• read() Returns the current feed value; reverts if it was not set by some valid mechanism.

• peep() Returns the next feed value (i.e. the one that will become the current value upon the next poke() call), and a boolean indicating whether it is valid.
