Bootstrapping Dynamic Factory Rule ObjectDynamic Hooks BehavioralProcessCreationalGUICoreInstrumental Includes the core patterns that are present in the basic implementation of AOMs. These are the basic patterns and they are the ones that govern this architectural style Includes the patterns that help to create instances of AOMs Includes the patterns for dynamically adding, removing or modifying behavior to the AOMs Includes the patterns that deal with how to present AOMs to end-users in applications Includes the patterns that deal with the process of creating AOMs. They establish guidelines for evolving frameworks and boundaries to avoid going up to the meta-levels far beyond than necessary. Includes patterns that help to instrument the usage, control, and instrumentation of AOMs. They also help to provide guidelines for non-functional requirements such as performance and auditability Sources for AOM Patterns and Applications AOM Common Architecture Behavior Classes with Attributes and Relationships StrategyType Cube Dependency Injection Extents… Type Square Uses to decuple types… Represent attributes as… Represent relationships using… Describe each property as… Handle null and default values with… Handle incomplete and default relationships with… PropertiesAccountability Controls effects of references on… Describes… Smart Variables Simple behaviour with… Uses / extends… Allows having versions of… Coordinates several… Can use… Rule Engine Registers changes… Versioning Helps… Context ObjectHistory Complex behavior… Interpreter Builder AOM Builder Manages states… Dynamic ViewsThree Examples White Box Framework Black Box Framework Component LibraryHot SpotsPluggable Objects Fine-Grained Objects Visual BuilderLanguage Tools Simple System Domain Specific Abstraction Time Manages several… Are registered using… Uses for interpreting description of entities… GUI Workflow Creates instances of… Extends… Decouple dependencies using… Creates instances of elements dinamically… Editor / Visual Language Property Renderer Renders one instance… Entity View Renders one instance… Can use… Workflow / Flow of Control Functions Temporal Rules Constraints / Validations Event Driven Transformations When get complex can be an… For more info on AOMs, visit www.adaptiveobjectmodel.com Leon Welicki ONO (Cableuropa S.A.U.) lwelicki@acm.org Joseph W.
