Class ComponentSnapshot

java.lang.Object
org.vaadin.addons.dramafinder.agent.ComponentSnapshot
public final class ComponentSnapshot extends Object
Produces a compact, human- and agent-readable summary of the Vaadin components currently present on a page.

Instead of dumping a full accessibility tree (which is large and noisy for Vaadin's shadow DOM and teleported overlays), this walks the light DOM for vaadin-* elements and emits one terse line per meaningful component, e.g.: 

 vaadin-grid — 12 rows, columns [Date, Amount, Status], 1 selected
 vaadin-combo-box "Category" = "Travel"
 notification: "Saved"
 vaadin-dialog-overlay open — "Confirm"
The result is orders of magnitude smaller than an accessibility-tree dump and captures exactly the state an agent needs to reason about the UI. It is also embedded in failure reports written by AgentReporting.
