Enum Class AgentState

java.lang.Enum<AgentState>

com.tnsai.hooks.events.AgentState

All Implemented Interfaces:

Serializable, Comparable<AgentState>, Constable

public enum AgentState
extends Enum<AgentState>

Lifecycle state of an Agent. Read via Agent.getState(); transitions surface as OnStateTransition hook events for observers.

Standard transition graph:

   CREATED ──▶ STARTING ──▶ RUNNING ──▶ STOPPING ──▶ STOPPED
      │           │            │
      └───────────┴────────────┴──────▶ FAILED  (terminal)
 

FAILED is terminal — agents cannot recover in-place; an operator must construct a new instance. STOPPED is also terminal but represents a clean shutdown rather than an error.

Since:

0.5.0 (issue #21; foundation seeded by #60)

Enum Constant Details

CREATED

public static final AgentState CREATED

Constructed but no lazy initialisation has run yet.

STARTING

public static final AgentState STARTING

Lazy initialisation in progress. chat() blocks or rejects.

RUNNING

public static final AgentState RUNNING

Ready to process messages. The only state in which chat() succeeds.

STOPPING

public static final AgentState STOPPING

stop() has been called; in-flight work is being drained.

STOPPED

public static final AgentState STOPPED

Fully stopped, resources released. Terminal — no transitions out.

FAILED

public static final AgentState FAILED

Unrecoverable error during initialisation or execution. Terminal — no transitions out; construct a new agent instance to retry.

Method Details

values

public static AgentState[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static AgentState valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
