Record Class AgentInit

java.lang.Object
java.lang.Record
com.tnsai.hooks.events.AgentInit
Record Components:
eventId - ULID-shaped correlation id
timestamp - when build() completed
context - surrounding hook context
All Implemented Interfaces:
AgentHookEvent, HookEvent
public record AgentInit(String eventId, Instant timestamp, HookContext context) extends Record implements AgentHookEvent
Fires once when AgentBuilder.build() completes, before the first chat() call (issue #60). Intended for one-time setup — resource allocation, state hydration, metric registration.

The issue's original spec included an AgentBuilderSnapshot field (full builder state at the moment of init). That snapshot is a cross-module concern — the builder lives in tnsai-core.agents, spans many optional features (roles, LLM, knowledge base, planner), and a useful snapshot type is non-trivial. The foundation slice omits it. Consumers today read identity from HookContext (agentId / agentClass / role / capabilities); a follow-up can add a typed snapshot without breaking this record's shape.

Since:
0.5.0 (issue #60)

  • Constructor Details

    • AgentInit

      public AgentInit(String eventId, Instant timestamp, HookContext context)
      Creates an instance of a AgentInit record class.
      Parameters:
      eventId - the value for the eventId record component
      timestamp - the value for the timestamp record component
      context - the value for the context record component

  • Method Details

    • eventType

      public String eventType()
      Description copied from interface: HookEvent
      Short stable string identifier of the event kind, e.g. "PreToolUse". Default implementation derives it from the concrete record's simple class name; concrete records may override if a different naming is desirable.
      Specified by:
      eventType in interface HookEvent

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • eventId

      public String eventId()
      Returns the value of the eventId record component.
      Specified by:
      eventId in interface HookEvent
      Returns:
      the value of the eventId record component

    • timestamp

      public Instant timestamp()
      Returns the value of the timestamp record component.
      Specified by:
      timestamp in interface HookEvent
      Returns:
      the value of the timestamp record component

    • context

      public HookContext context()
      Returns the value of the context record component.
      Specified by:
      context in interface HookEvent
      Returns:
      the value of the context record component
