kind
• get kind(): string
A string representing the objects "type", useful for segmenting storage, among other things. Defaults to the lowercase class name, but can be overwritten by subclasses

Methods
_fromRaw
▸ Protected _fromRaw(raw): void
Restore values from a raw object. The default implementation simply copies over all iterable properties from the base object. Overwrite this method for properties that require special treatment
Parameters
| Name | Type |
|---|---|
raw |
any |
Returns
void
Inherited from
Defined in
_toRaw
▸ Protected _toRaw(version): any
Transform this object into a raw javascript object used for serialization. The default implementation simply copies all iterable properties not included in the [[exlude]] array and calls toRaw on any properties that are themselfes instances of Serializable. This method should be overwritten by subclasses if certain properties require special treatment.
Parameters
| Name | Type |
|---|---|
version |
undefined | string |
Returns
any

clone
▸ clone(): Attachment
Creates a deep clone of the object
Returns
Inherited from
Defined in
fromBytes
▸ fromBytes(bytes): Attachment
Deserializes the object from a byte array
Parameters
| Name | Type |
|---|---|
bytes |
Uint8Array |
Returns

Defined in
fromFile
▸ fromFile(file): Promise<Attachment>
Parameters
| Name | Type |
|---|---|
file |
File |
Returns
Promise<Attachment>
Defined in
fromJSON
▸ fromJSON(json): Attachment
Deserializes the object from a JSON string
Parameters
| Name | Type |
|---|---|
json |
string |
Returns
Inherited from
Defined in
fromRaw
▸ fromRaw(raw): Attachment
Restores propertiers from a raw object of the same form generated by
toRaw. The base implementation blindly copies
over values from the raw object via Object.assign so subclasses should
explictly process any propertyies that need special treatment.
Also takes are of validation and "upgrading" in case the raw object has an old version. Use the protected _fromRaw method to implement subclass-specific behavior.
Parameters
| Name | Type |
|---|---|
raw |
any |
Returns

Defined in
getData
▸ getData(): Promise<Uint8Array>
Decrypts and extracts the plain text data from the container. This will usually require unlocking the container first.
Returns
Promise<Uint8Array>
Inherited from
Defined in
lock
▸ lock(): void
Locks the container, removing the possibility to extract the plain text data via getData until the container is unlocked again. Subclasses extending this class must take care to delete any keys or other sensitive data that may have been stored temporarily after unlocking the container.
Returns
void
Inherited from
Defined in
setData
▸ setData(data): Promise<void>
Encrypts the provided data and stores it in the container
Parameters
| Name | Type |
|---|---|
data |
Uint8Array |
Returns
Promise<void>

Defined in
toBytes
▸ toBytes(): Uint8Array
Returns a serialization of the object in form of a byte array
Returns
Uint8Array

toDataURL
▸ toDataURL(): Promise<string>
Returns
Promise<string>
Defined in
toFile
▸ toFile(): Promise<File>
Returns
Promise<File>
Defined in
toJSON
▸ toJSON(): string
Returns a JSON serialization of the object
Returns
string

Defined in
toObjectURL
▸ toObjectURL(): Promise<string>
Returns
Promise<string>
Defined in
toRaw
▸ toRaw(version?): any
Creates a raw javascript object representation of the class, which can be used for storage or data transmission. Also handles "downgrading" to previous versions. Use _toRaw for subclass-specific behavior.
Parameters
| Name | Type |
|---|---|
version? |
string |
Returns
any

toText
▸ toText(): Promise<string>
Returns
Promise<string>
Defined in
unlock
▸ unlock(key): Promise<void>
Unlocks the container, making it possible to extract the plain text data via getData. The type of secret provided will differ based on the encryption scheme used by implemenations.
Parameters
| Name | Type |
|---|---|
key |
Uint8Array |
Returns
Promise<void>
Inherited from
Defined in
validate
▸ validate(): boolean
This is called during deserialization and should verify that all properties have been populated with values of the correct type. Subclasses should implement this method based on their class structure.
Returns
boolean
