Class TokenTable

java.lang.Object
tech.guilhermekaua.spigotboot.inventoryapi.internal.state.TokenTable
@Internal public final class TokenTable extends Object
Per-view registry of state tokens. Tokens register during view construction and receive sequential ids; registration is frozen once the view is registered. Registration and freezing are expected on a single thread; the frozen flag is volatile so the guard is visible if the engine freezes from another thread.
