java.lang.Object
io.fluxzero.sdk.tracking.client.InMemoryMessageStore
io.fluxzero.sdk.scheduling.client.InMemoryScheduleStore
All Implemented Interfaces:

public class InMemoryScheduleStore extends InMemoryMessageStore implements SchedulingClient
An in-memory implementation of a scheduling store that allows the scheduling, retrieval, and management of scheduled messages. It extends `InMemoryMessageStore` to reuse the functionalities for storing and managing messages and implements `SchedulingClient` to support scheduling-specific operations.

This implementation provides thread-safe mechanisms for scheduling, retrieving, and cancelling messages. Messages are scheduled to be processed at specific timestamps, with support for expiration and filtering of schedules.
