abstractions

AXOpen.Abstractions

[!INCLUDE General]

AXOpen.Abstractions is the core abstractions package for the AXOpen framework. It defines the interfaces and enumeration types that all AXOpen implementations depend on. This library contains no concrete classes; it establishes the contracts that concrete libraries such as AXOpen.Core implement.

Interfaces

Interface	Namespace	Description
IAxoContext	AXOpen.Core	Defines the contract for the application's cyclic execution context. Provides identity creation, cycle counting, and service injection points for RTC, logging, runtime metering, and messaging.
IAxoObject	AXOpen.Core	Base contract for all AXOpen objects. Provides identity, context access, parent traversal, message aggregation, and validity checks.
IAxoRtc	AXOpen.Rtc	Real-time clock abstraction. Returns the current UTC date and time.
IAxoRtm	AXOpen.Rtm	Runtime meter abstraction. Returns the elapsed time.
IAxoLogger	AXOpen.Logging	Logging abstraction (extends IAxoLoggerConfig). Provides methods to log messages with level, sender, and message code.
IAxoLoggerConfig	AXOpen.Logging	Configuration interface for the logger. Allows setting the minimum log level.
IAxoMessenger	AXOpen.Core	Marker interface for messenger objects.
IAxoMessagingServices	AXOpen.Core	Messaging service contract. Provides message queuing, suspension, resumption, and downstream message requalification.

Enumerations

Enum	Namespace	Description
eLogLevel	AXOpen.Logging	Defines log severity levels: NoCat, Verbose, Debug, Information, Warning, Error, Fatal.
eAxoMessageCategory	AXOpen.Messaging	Defines message categories: None, Info, Potential, Warning, Error, ProgrammingError, Critical.
