A parsed CSS stylesheet resource.

Contains style rules, at-rules, and CSS variables with efficient indexing for selector matching. The raw CSS source text is stored for serialization; parsed data is rebuilt on deserialization.

Constructors

constructor

  • new StyleSheet(cssText, uuid?, isInternalConstructor?): StyleSheet

  • Creates a new stylesheet resource from CSS source text.

    Parameters

    • cssText: string

      The CSS source text.

    • Optionaluuid: UUID

      Optional UUID for the resource.

    • OptionalisInternalConstructor: boolean

    Returns StyleSheet

    Handle to the created stylesheet resource.

Accessors

handle

isDestroyed

  • get isDestroyed(): boolean

  • Determines if the resource is destroyed.

    Returns boolean

    Note

    This can happen when the Resource was forcefully unloaded or reverted. For this reason, it is safer to hold on to a instead of directly referencing a resource pointer, as the current Resource can always be retrieved via .value.

isEmpty

  • get isEmpty(): boolean

  • Returns true if the stylesheet is empty.

    Returns boolean

metaData

name

  • get name(): string

  • Name of the resource. Use primarily for easier identification and not important to the engine itself.

    Returns string

ruleCount

  • get ruleCount(): number

  • Returns the number of style rules.

    Returns number

sourceText

  • get sourceText(): string

  • Gets the raw CSS source text.

    Returns string

uuid

  • get uuid(): UUID

  • Returns a universally unique identifier of this resource.

    Returns UUID

Methods

duplicate

  • duplicate(): Resource

  • Duplicates the resource and creates a unique UUID for the duplicated resource.

    Returns Resource

    The duplicated resource or null, if the duplication failed.

onCreate

  • onCreate(): void
  • Virtual

    Method called by RSX to perform actions required after the creation of the resource.

    Returns void

onDeserializationEnded

  • onDeserializationEnded(): void
  • Virtual

    Method called by RSX to perform any operations needed after deserialization.

    Returns void

    Note

    Use this API to restore your serializable data into live objects.

onDisable

  • onDisable(): void
  • Virtual

    Method called by RSX to disable the resource.

    Returns void

    Note

    Use this API to deactivate the resource before it is serialized.

onEnable

  • onEnable(): void
  • Virtual

    Method called by RSX to enable the resource.

    Returns void

    Note

    Use this API to activate the resource after it has been disabled by serialization.

onInitialize

  • onInitialize(): void
  • Virtual

    Method called by RSX to perform initialization of the resource.

    Returns void

    Note

    Use this API to initialize data and default construct all fields.

onSerializationStart

  • onSerializationStart(): void
  • Virtual

    Method called by RSX to perform any operations before serialization.

    Returns void

    Note

    Use this API to bake your live data into serializable data.

revert

  • revert(): boolean

  • Reverts the resource to the on-disk representation.

    Returns boolean

    Note

    This is a potentially expensive call, as it needs to deserialize and replace all existing in-memory resource handles.
