Class SysmonAdapters

java.lang.Object
com.guinetik.hexafun.examples.sysmon.SysmonAdapters
public final class SysmonAdapters extends Object
Output adapters for SystemMetrics - transforms domain data to presentation formats.

This is where the hexagonal architecture shines: same domain object, four completely different presentations. The domain knows nothing about how it will be displayed.

  • TUI - Colorful progress bars with warnings
  • CLI - Plain text for scripting
