Description copied from class: AbstractChildEntityDefinition

Resolve the target of an incoming CommandMessage to the right Child Entity. Returns the Child Entity the msg needs to be routed to.

Specified by:

resolveCommandTarget in class AbstractChildEntityDefinition

Type Parameters:

T - the type T of the given parent Entity

Parameters:

msg - the CommandMessage which is being resolved to a target entity

parent - the parent Entity of type T of this Child Entity
