Overview

An Agent Resolver takes a concrete user (or other account/actor) object and resolves it into the set of Checkpoint::Agents that the user represents. This has the effect of allowing a Permit to any of those agents to take effect when authorizing an action by this user.

This implementation only resolves the user into one agent, using the default conversion.

To extend the set of Checkpoint::Agents resolved, implement a specialized version that returns an array of agents from #resolve. This customized implementation would typically be injected to an application-wide Checkpoint::Authority, rather than being used directly.

For example, a custom resolver might add a group agent for each group that the user is a member of, or IP address-based geographical regions or organizational affiliations.
