Methods

  • Add one or more tags.

    Parameters

    • Rest...tags: string[]

      List of tags.

    Returns void

  • Search the array for this object and return the corresponding index.

    If strict is false, is() is used to compare. If strict is true, equals() is used.

    Parameters

    • array: any[]

      The array to search.

    • Optionalstrict: boolean

      Whether to use stronger comparison.

    Returns number

    The index if the object is in the array, -1 if it isn't.

  • Check if this is a sleeping reference.

    Returns boolean

  • Check if this is a sleeping reference and throw an error if so.

    Returns void

  • Returns Promise<{
        message: string;
        result: boolean;
    }>

  • Delete the object from storage.

    Returns Promise<boolean>

    True on success, false on failure.

  • Perform a more strict comparison of this object to another.

    Parameters

    • object: any

      The object to compare.

    Returns boolean

    True or false.

  • Get a patch of this entity's dirty data to be applied on the server.

    Returns EntityPatch

  • Check that the entity has all of the given tags.

    Parameters

    • Rest...tags: string[]

      List of tags.

    Returns boolean

    True or false.

  • Check whether this object is in an array.

    If strict is false, is() is used to compare. If strict is true, equals() is used.

    Parameters

    • array: any[]

      The array to search.

    • Optionalstrict: boolean

      Whether to use stronger comparison.

    Returns boolean

    True if the object is in the array, false if it isn't.

  • Perform a less strict comparison of this object to another.

    Parameters

    • object: any

      The object to compare.

    Returns boolean

    True or false.

  • Check whether a property is dirty.

    To be a dirty property, it must have been set or deleted since the entity was initialized. A clean property existed on initialization and hasn't been set or deleted. An untracked property didn't exist on initialization and hasn't been set or deleted.

    Note that this doesn't necessarily mean the property has changed. It could have been set to the same value, or created and then deleted.

    Entities are initialized when they are pulled from the server or saved. This is done with the $init method.

    Parameters

    • property: string

      The name of a property.

    Returns null | boolean

    True if it's dirty, false if not, and null if it's not tracked.

  • Save the object's dirty data to storage.

    Returns Promise<boolean>

    True on success, false on failure.

  • Refresh the object from storage. (Bypasses Nymph's cache.)

    If the object has been deleted from storage, the database cannot be reached, or a database error occurs, refresh() will return 0.

    Returns Promise<boolean | 0>

    False if the data has not been saved, 0 if it can't be refreshed, true on success.

  • Remove one or more tags.

    Parameters

    • Rest...tags: string[]

      List of tags.

    Returns void

  • Save the object to storage.

    Returns Promise<boolean>

    True on success, false on failure.

  • Call an instance method on the server version of this entity.

    The entity's data will be sent up to the server as well, so the server's state can match the client's state. It won't be propagated into the DB, though.

    Parameters

    • method: string

      The name of the method.

    • params: Iterable<any, any, any>

      The parameters to call the method with.

    • Optionalstateless: boolean

      Whether the server should return, and the client update, the data in the entity after the method has run.

    Returns Promise<any>

    The value that the method on the server returned.

  • Ready this entity's data, and the data of entity's within this one's.

    Parameters

    • Optionallevel: number

      The number of levels deep to wake. If undefined, it will keep going until there are no more entities. (Careful of infinite loops.)

    Returns Promise<Entity<GroupData>>

    The entity.

  • Create or retrieve a new entity instance.

    Note that this will always return an entity, even if the GUID is not found.

    Type Parameters

    Parameters

    • this: (new () => E)
        • new (): E
        • Returns E

    • Optionalguid: string

      An optional GUID to retrieve.

    Returns Promise<E & EntityDataType<E>>

  • Create a new sleeping reference instance.

    Sleeping references won't retrieve their data from the server until they are readied with $wake() or a parent's $wakeAll().

    Type Parameters

    Parameters

    • this: (new () => E)
        • new (): E
        • Returns E

    • reference: EntityReference

      The Nymph Entity Reference to use to wake.

    Returns E & EntityDataType<E>

    The new instance.

  • Call a static method on the server version of this entity.

    Parameters

    • method: string

      The name of the method.

    • params: Iterable<any, any, any>

      The parameters to call the method with.

    Returns Promise<any>

    The value that the method on the server returned.

  • Call a static iterator method on the server version of this entity.

    Parameters

    • method: string

      The name of the method.

    • params: Iterable<any, any, any>

      The parameters to call the method with.

    Returns Promise<AbortableAsyncIterator<any>>

    An iterator that iterates over values that the method on the server yields.
