Methods

  • Parameters

    • __namedParameters: { pack?: null; parentCollection?: null } = {}

    Returns void

  • Internal

    Identify the collection in a parent Document that this Document belongs to, if any.

    Parameters

    • OptionalparentCollection: null | string

      An explicitly provided parent collection name.

    Returns null | string

  • Test whether a given User has permission to perform some action on this Document

    Parameters

    • user: BaseUser

      The User attempting modification

    • action: string

      The attempted action

    • Optionaldata: object = {}

      Data involved in the attempted action

    Returns boolean

    Does the User have permission?

  • Obtain a reference to the Array of source data within the data object for a certain embedded Document name

    Parameters

    • embeddedName: string

      The name of the embedded Document type

    Returns DocumentCollection

    The Collection instance of embedded Documents of the requested type

  • Get an embedded document by its id from a named collection in the parent document.

    Parameters

    • embeddedName: string

      The name of the embedded Document type

    • id: string

      The id of the child document to retrieve

    • Optionaloptions: { invalid?: boolean; strict?: boolean } = {}

      Additional options which modify how embedded documents are retrieved

      • Optionalinvalid?: boolean

        Allow retrieving an invalid Embedded Document.

      • Optionalstrict?: boolean

        Throw an Error if the requested id does not exist. See Collection#get

    Returns Document<object, DocumentConstructionContext>

    The retrieved embedded Document instance, or undefined

    If the embedded collection does not exist, or if strict is true and the Embedded Document could not be found.

  • Get the value of a "flag" for this document See the setFlag method for more details on flags

    Parameters

    • scope: string

      The flag scope which namespaces the key

    • key: string

      The flag key

    Returns any

    The flag value

  • Get the explicit permission level that a User has over this Document, a value in CONST.DOCUMENT_OWNERSHIP_LEVELS. Compendium content ignores the ownership field in favor of User role-based ownership. Otherwise, Documents use granular per-User ownership definitions and Embedded Documents defer to their parent ownership.

    This method returns the value recorded in Document ownership, regardless of the User's role, for example a GAMEMASTER user might still return a result of NONE if they are not explicitly denoted as having a level.

    To test whether a user has a certain capability over the document, testUserPermission should be used.

    Parameters

    • Optionaluser: BaseUser

      The User being tested

    Returns DocumentOwnershipNumber

    A numeric permission level from CONST.DOCUMENT_OWNERSHIP_LEVELS

  • For Documents which include game system data, migrate the system data object to conform to its latest data model. The data model is defined by the template.json specification included by the game system.

    Returns object

    The migrated system data object

  • Reset the state of this data instance back to mirror the contained source data, erasing any changes.

    Returns void

  • Assign a "flag" to this document. Flags represent key-value type data which can be used to store flexible or arbitrary data required by either the core software, game systems, or user-created modules.

    Each flag should be set using a scope which provides a namespace for the flag to help prevent collisions.

    Flags set by the core software use the "core" scope. Flags set by game systems or modules should use the canonical name attribute for the module Flags set by an individual world should "world" as the scope.

    Flag values can assume almost any data type. Setting a flag value to null will delete that flag.

    Parameters

    • scope: string

      The flag scope which namespaces the key

    • key: string

      The flag key

    • value: any

      The flag value

  • Update the DataModel locally by applying an object of changes to its source data. The provided changes are expanded, cleaned, validated, and stored to the source data object for this model. The provided changes argument is mutated in this process. The source data is then re-initialized to apply those changes to the prepared data. The method returns an object of differential changes which modified the original data.

    Parameters

    • changes: object = {}

  • Validate the data contained in the document to check for type and content. If changes are provided, missing types are added to it before cleaning and validation. This mutates the provided changes. This function throws an error if data within the document is not valid.

    Parameters

    Returns boolean

    Whether the data source or proposed change is reported as valid. A boolean is always returned if validation is non-strict.

    An error thrown if validation is strict and a failure occurs.
