Represents an endpoint for an AMQP connection..
An AMQP terminus acts as either a source or a target for messages, but never as both. Every Link is associated iwth both a source and a target Terminus that is negotiated during link establishment.
A terminus is composed of an AMQP address along with a number of other properties defining the quality of service and behavior of the Link.
Indicates a Terminus with durably held configuration, but not the delivery state.
A special target identifying a transaction coordinator.
Indicates a Terminus with both durably held configuration and durably held delivery states.
The receiver gets all messages.
The receives compete for messages.
The behavior is defined by the nod.e
The terminus is never considered orphaned.
The terminus is orphaned when the parent connection is closed.
The terminus is orphaned when the parent link is closed.
The terminus is orphaned whent he parent sessio is closed.
Indicates a non-durable Terminus.

Indicates a source for messages.
Indicates a target for messages.

Access and modify the AMQP capabilities data for the Terminus.
This operation will return an instance of Data that is valid until the Terminus is freed due to its parent being freed. Any data contained in the object will be sent as the AMQP properties for the parent Terminus instance.
NOTE: this MUST take the form of a symbol keyed map to be valid.
@return [Data] The terminus capabilities.

Access and modify the AMQP filter set for a source terminus. Only relevant for a message source.
This operation will return an instance of Data that is valid until the Terminus is freed due to its parent being freed. Any data contained in the object will be sent as the AMQP properties for the parent Terminus instance.
NOTE: this MUST take the form of a symbol keyed map to be valid.
