Architecture Components:
This document describes the major components shown in the project architecture diagram and explains their roles in the system.
Element API- The Element API provides the primary interface for interacting with the system’s elements. It exposes declarations, signals, and commands that allow external components to create and manage element instances. It acts as the entry point for defining element behavior and communicating with the interpreter and scheduler.
Specification- The Specification component defines the structure and behavior of elements used in the system. It contains a specification table that describes element classes and their properties. This information is used by the interpreter to understand how each element should behave during execution.
Warehouse- The Warehouse stores element instances and their identifiers. It acts as a storage and retrieval layer for runtime elements and allows the system to access element instances during execution. The warehouse also supports queries and updates related to element state.
Tree- The Tree represents the syntax tree generated from parsed input. It organizes the structure of the program or specification in a hierarchical form. Each node corresponds to elements and instructions defined in the system.
Library Elements- Library Elements contain predefined abstract classes and reusable element definitions provided by the system. These elements can be used directly by developers when building programs.
Plugin Elements- Plugin Elements extend the functionality of the system by allowing additional element classes to be loaded dynamically. They provide a way to add new behaviors without modifying the core system.
Symbol Table- The Symbol Table stores declarations, identifiers, and references used during program execution. It helps resolve variable names, element references, and other symbols required during interpretation.
Scheduler- The Scheduler manages execution flow and determines the order in which tasks are executed. It maintains the execution context and coordinates with the interpreter to ensure that instructions are processed correctly.
Parser- The Parser processes input specifications or scripts and converts them into structured syntax tree nodes. These nodes are then passed to the Tree component for further processing.
Interpreter- The Interpreter executes the logic defined in the specifications and syntax tree. It interacts with the symbol table, scheduler, and specification data to run instructions and manage element states.
Monitor- The Monitor tracks system activity and execution statistics. It collects runtime information such as states, call stacks, and element instance statistics. This component is useful for debugging and observing system behavior.
Data Flow Between Components:
The arrows in the architecture diagram represent the flow of data and control between system components. The Parser generates syntax tree nodes that are stored in the Tree. The Tree provides element instance information used by the Warehouse. The Specification defines element classes that are used by the Interpreter. The Interpreter interacts with the Scheduler to manage execution order. The Symbol Table provides declarations and query results required during interpretation. The Monitor receives runtime data and statistics from the interpreter and other components. Library Elements and Plugin Elements provide abstract element classes that are exposed through the Element API.
These interactions allow the system to parse specifications, manage element instances, execute logic, and monitor system behavior.
