Easy Rules
Easy-rules ist eine Java-Business-Rules-Engine zur Definition und Evaluierung bedingter Logik und Aktionen. Sie dient als Framework, um einfache Logikeinheiten in komplexe Hierarchien aus zusammengesetzten Regeln zu organisieren und als iterativer Regelprozessor zu fungieren.
Das System fungiert als Expression-Language-Rules-Engine, die es ermöglicht, Regelbedingungen und Aktionen über dynamische Ausdrücke anstelle von statisch kompiliertem Code zu definieren. Dies ermöglicht die Konfiguration von Geschäftslogik, die das Anwendungsverhalten ändern kann, ohne den Quellcode neu kompilieren zu müssen.
Die Engine unterstützt faktenbasiertes Matching, um Aktionen auszulösen, wenn Bedingungen übereinstimmen, und nutzt sowohl prioritätsbasierte sequentielle Verarbeitung als auch iterative Ausführungsschleifen, die Regeln abfeuern, bis ein stabiler Zustand erreicht ist. Sie verwaltet diese Prozesse durch ein Condition-Action-Muster und eine zusammengesetzte Regelhierarchie.
Features
- Business Rules Engine - Provides a full engine for defining, managing, and executing conditional business logic and actions.
- Java Frameworks - Provides a complete framework for defining and evaluating conditional business logic and actions within Java applications.
- Business Rule Engines - Allows users to define operational logic using annotations, fluent interfaces, or external descriptors.
- Fact-Based Rule Triggering - Compares registered rules against collections of data to trigger associated actions when conditions align.
- Dynamic Expression Languages - Allows rule conditions and actions to be defined via a dynamic expression language for runtime evaluation.
- Business Rule Composition - Enables combining multiple simple rules into composite structures to organize complex business logic hierarchies.
- Complex Business Rule Composition - Combines multiple simple rules into composite structures to create sophisticated and layered business logic.
- Composite Rule Hierarchies - Implements a hierarchy for grouping simple rules into nested composite structures to organize complex business logic.
- Composite Rules Frameworks - Acts as a system for organizing simple logic units into complex hierarchies of grouped composite rules.
- Condition-Action Patterns - Provides a condition-action pattern to trigger specific executable behaviors when a set of runtime facts is met.
- Configuration-Driven Logic - Defines business rules using expression languages to change application behavior without requiring source code recompilation.
- Expression Languages - Provides an engine for parsing and executing custom business logic defined as strings at runtime.
- Fact-Based Matching - Matches registered rule predicates against runtime data to determine which actions should be executed.
- Java-Based Rule Evaluation - Checks data against a set of predefined conditions to trigger specific actions within a Java application.
- Rule Execution Engines - Implements an execution engine that repeatedly evaluates facts against rules until a stable state is reached.
- Business Workflow Automation - Organizes nested and composite rules to manage layered logic hierarchies and sequential execution paths.
- Iterative Fact Processing - Evaluates a set of data repeatedly until all applicable rules have been fired and no further conditions are met.
- Iterative Rule Evaluation - Evaluates and fires applicable rules repeatedly until no more conditions are met, allowing actions to trigger further executions.
- Iterative Rule Execution - Implements iterative execution loops that fire applicable rules repeatedly until a stable state is reached.
- Priority-Based Rule Processing - Executes registered rules in a specific order based on assigned weights or priorities.
- Sequential Rule Execution - Runs a set of registered rules against facts and triggers actions based on priority and condition matches.
- General Purpose Orchestration - Simple rules engine for Java-based logic execution.
