TokenAwarePolicy Class

A wrapper load balancing policy that adds token awareness to a child policy.

This policy encapsulates another policy. The resulting policy works in the following way:

The Distance(Host) method is inherited from the child policy.
The host yielded by the NewQueryPlan(String, IStatement) method will first return the Local replicas for the statement, based on the RoutingKey.

The TokenAwarePolicy type exposes the following members.

Constructors

	TokenAwarePolicy	Creates a new TokenAware policy that wraps the provided child load balancing policy.

Methods

	Name	Description
	Distance	Return the HostDistance for the provided host.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Initialize
	NewQueryPlan	Returns the hosts to use for a new query. The returned plan will first return replicas (whose HostDistance for the child policy is Local) for the query if it can determine them (i.e. mainly if IStatement.RoutingKey is not null). Following what it will return the plan of the child policy.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
