Accessors

failureMode

get failureMode(): FailureMode
Determines how a parent object should handle initialization failure in this object. The default is "warn".
- "error": support/InitializeError!InitializeError is thrown.
- "warn": Message is logged and support/InitializableBase!InitializeWarningEvent is raised.
- "ignore": support/InitializableBase!InitializeWarningEvent is raised.
Returns FailureMode
Inherited from EntityBase.failureMode
set failureMode(value): void
Parameters
- value: FailureMode
Returns void
Inherited from EntityBase.failureMode

id

get id(): string
The unique ID for this entity.

Returns string
Inherited from EntityBase.id

isDestroyed

get isDestroyed(): boolean
See support/InitializableBase!Initializable.isDestroyed.

Returns boolean
Inherited from EntityBase.isDestroyed

isInitialized

get isInitialized(): boolean
See support/InitializableBase!Initializable.isInitialized.

Returns boolean
Inherited from EntityBase.isInitialized

itemType

get itemType(): string
The item type for this entity when it participates in an App.

Returns string
Inherited from EntityBase.itemType

Methods

`Protected`_getSerializableProperties

_getSerializableProperties(): PropertyDefs<AttachmentProperties>
The property keys and their metadata that are used to implement serializing and deserializing the class instance.

Returns PropertyDefs<AttachmentProperties>
Overrides EntityBase._getSerializableProperties

`Protected`_initializableChildCollections

_initializableChildCollections(): IterableIterator<Collection<InitializableBase<InitializableBaseProperties>>, any, any>
Collections of child items to initialize. Items that fail to initialize are removed from the collection.

Returns IterableIterator<Collection<InitializableBase<InitializableBaseProperties>>, any, any>
Inherited from EntityBase._initializableChildCollections

`Protected`_initializeChildren

_initializeChildren(): Promise<void>
Initializes child entities.

Returns Promise<void>
Inherited from EntityBase._initializeChildren

`Protected`_onDestroy

_onDestroy(): Promise<void>
Called to perform cleanup. Subclasses should override this method rather than destroy() to perform custom cleanup.

Returns Promise<void>
Inherited from EntityBase._onDestroy

`Protected`_onInitialize

_onInitialize(): Promise<void>
Called to perform initialization of the support/InitializableBase!InitializableBase. Subclasses should override this method rather than initialize() to perform custom initialization.

Returns Promise<void>
Inherited from EntityBase._onInitialize

`Protected`_postInitialize

_postInitialize(): Promise<void>
Called after normal initialization. Note: Child items are initialized before this is called.

Returns Promise<void>
Inherited from EntityBase._postInitialize

`Protected`_toPropertyDef

_toPropertyDef<T>(def): PropertyDef<T>
Converts the value to a PropertyDef object.
Type Parameters
- T
Parameters
- def: PropertyDefSerializeMode | PropertyDefSerializeMode[] | PropertyDef<T>
  The value to convert.
Returns PropertyDef<T>
Inherited from EntityBase._toPropertyDef

assignProperties

assignProperties(properties): void
Parameters
- properties: Partial<AttachmentProperties>
Returns void

Parameters
- properties: Partial<AttachmentProperties>
Returns Promise<void>
Inherit Doc
Inherited from EntityBase.assignPropertiesAsync

destroy

destroy(): Promise<void>
A clean-up function that should get called whenever the item is disposed of.

Returns Promise<void>
Inherited from EntityBase.destroy

finishAssignProperties

finishAssignProperties(): Promise<void>
Returns Promise<void>
Inherit Doc
Inherited from EntityBase.finishAssignProperties

getSerializableProperties

getSerializableProperties(serializeMode?): PropertyDefs<AttachmentProperties>
Returns the serializable properties.
Parameters
- OptionalserializeMode: SerializeMode
  Optional. If specified, only properties that support the given serialization mode will be returned.

initialize

initialize(): Promise<void>
Initializes the item.

Returns Promise<void>
Inherited from EntityBase.initialize

toItemUri

toItemUri(): string
Creates an item:// URI reference to this entity.
