API Reference ​

Overview ​

This section provides comprehensive API documentation for all ECO SDK components and modules.

Core APIs ​

Core API ​

Fundamental system APIs including:

  • Memory Management
  • File System Operations
  • Interface Bus Communication
  • DateTime Utilities
  • Logging System
  • Mathematical Functions (FFT)

Component API ​

Detailed component documentation:

  • Eco.Core1
  • Eco.FileSystemManagement1
  • Eco.InterfaceBus1
  • Eco.MemoryManager1
  • EcoDateTime1
  • EcoLog1
  • EcoMathFFT1

Usage Examples ​

Basic Setup ​

javascript
// Initialize the ECO SDK
const eco = require('eco-sdk');

// Create core components
const core = new eco.Core1();
const memoryManager = new eco.MemoryManager1();
const fileSystem = new eco.FileSystemManagement1();

// Initialize components
core.initialize();
memoryManager.initialize();
fileSystem.initialize();

Memory Management ​

javascript
// Allocate memory
const buffer = memoryManager.allocateMemory(1024, 'HEAP');

// Use the buffer
// ... your code here ...

// Deallocate when done
memoryManager.deallocateMemory(buffer);

File Operations ​

javascript
// Create a directory
fileSystem.createDirectory('/tmp/myapp');

// Write to a file
fileSystem.writeFile('/tmp/myapp/config.txt', 'Configuration data');

// Read from a file
const data = fileSystem.readFile('/tmp/myapp/config.txt');

Component Communication ​

javascript
// Create interface bus
const bus = new eco.InterfaceBus1();

// Register components
bus.registerComponent(core);
bus.registerComponent(memoryManager);
bus.registerComponent(fileSystem);

// Send messages between components
bus.sendEvent('memory-request', { size: 1024, type: 'HEAP' });

Error Handling ​

All APIs follow consistent error handling patterns:

  • Methods return null or false on failure
  • Detailed error information is logged
  • Components maintain state after errors
  • Use try-catch blocks for exception handling
javascript
try {
  const result = memoryManager.allocateMemory(1024, 'HEAP');
  if (result === null) {
    console.error('Memory allocation failed');
    return;
  }
  // Use the allocated memory
} catch (error) {
  console.error('Unexpected error:', error);
} finally {
  // Cleanup if needed
}

Performance Considerations ​

Memory Management ​

  • Minimize allocations in performance-critical code
  • Use appropriate memory types for different use cases
  • Monitor memory usage regularly
  • Implement proper cleanup patterns

File Operations ​

  • Use buffering for large file operations
  • Implement proper error handling for file I/O
  • Consider asynchronous operations for better performance
  • Monitor disk space usage

Component Communication ​

  • Keep messages small and focused
  • Use appropriate event types
  • Implement proper message handling
  • Monitor communication performance

Best Practices ​

  1. Initialization: Always initialize components before use
  2. Cleanup: Properly deallocate resources when done
  3. Error Handling: Implement comprehensive error handling
  4. Monitoring: Monitor component status and performance
  5. Documentation: Keep your API usage well-documented

Troubleshooting ​

Common Issues ​

  1. Memory Leaks: Ensure all allocated memory is deallocated
  2. File Permissions: Check file system permissions
  3. Component Communication: Verify component registration
  4. Performance: Monitor resource usage regularly

Debugging ​

Use the logging system to debug issues:

javascript
// Enable debug logging
log.setLogLevel('DEBUG');

// Add debug information
log.debug('Starting operation', { operation: 'memory-allocation' });

// Check component status
const status = core.getStatus();
console.log('Core status:', status);
