Features

• Application State Machines - Implements a .NET state machine library for managing behavioral transitions and lifecycles of application-level objects.
• Architectural State Machines - Provides a .NET state machine library for managing transitions between complex object states within an application architecture.
• Application State Management - Manages complex object behaviors and application logic through defined states and transitions to eliminate nested conditionals.
• External State Stores - Provides an external state store mechanism to decouple state tracking from machine logic via getter and setter delegates.
• State Transition Handlers - Executes synchronous or asynchronous logic during state changes with access to trigger and source state details.
• State Lifecycle Actions - Automatically runs specific setup and cleanup logic when a state is entered or exited.
• Asynchronous State Transition Orchestration - Orchestrates state transitions and guard conditions using asynchronous tasks to ensure application responsiveness.
• Hierarchical State Composition - Supports hierarchical state organization where child states inherit transitions and behaviors from superstates.
• Asynchronous State Transitions - Executes state transitions, entry, and exit handlers asynchronously to prevent thread blocking.
• Transition Guard Predicates - Evaluates boolean predicate functions at runtime to determine the destination state when multiple transitions exist.
• Transition Guards - Evaluates conditional logic via predicate functions to resolve destination states for triggers.
• Hierarchical State Machines - Implements hierarchical state machines that organize workflows into parent and child states with behavioral inheritance.
• State Persistence Frameworks - Provides a framework for reading and writing the current state to external properties or databases to maintain continuity.
• State Transition Mapping - Maps trigger events to source and destination states to define the system's logical flow.
• State Graph Export - Exports internal state machine configurations into visual graph formats like DOT and Mermaid.
• State Machine Visualizations - Generates DOT and Mermaid graph definitions to visualize state machine configurations as diagrams.
• Parametric Transitions - Enables sending data along with a trigger to influence the behavior of state transitions or resulting actions.
• Parametric Trigger Dispatch - Allows passing strongly typed data through triggers to dynamically resolve the next state or influence transition logic.
• Fluent Configuration APIs - Offers a fluent-API configuration for defining state transitions and behaviors using method-chaining.
• Internal Transitions - Processes triggers that execute logic without altering the current state of the machine.
• State Change Observers - Provides mechanisms to trigger callbacks and synchronize application logic when state transitions occur.
• Delegate-Based Action Execution - Implements state entry, exit, and transition actions by invoking registered C# delegates and asynchronous tasks.
• State Transition Validation - Verifies if a trigger can be fired and provides details on unmet guard conditions.
• Workflow Visualizations - Generates visual representations of business logic and state flows using DOT and Mermaid diagram formats.
• Scheduling and Automation - State machine creation library.
• Architecture Patterns - State machine implementation for managing application logic.
• State Machines - Library for creating state machines in code.
