DittoDocumentIDPath
public struct DittoDocumentIDPath
Provides an interface to specify a path to a key in a document ID that you can then call a function on to get
the value at the specified key as a specific type. You obtain a DittoDocumentIDPath
by subscripting a
DittoDocumentID
and you can then further subscript a DittoDocumentIDPath
to further specify the key of
the document ID that you want to get the value of. This is only really useful if you’re working with a document
ID whose underlying value is a dictionary or an array.
-
Used to specify a path to a key in the document ID that you can subscript further to access a nested key in the document ID.
Declaration
Swift
public subscript(key: String) -> DittoDocumentIDPath { get }
Parameters
key
The next part of the path needed to get to the key in the document ID you wish to get the value of.
Return Value
The same
DittoDocumentIDPath
object with the provided key incorporated into the document ID path. -
Used to specify an index in the array at the preceding key-path specified through the subscripting defined previously. You can subscript the return value further to access a further nested key in the document ID.
Declaration
Swift
public subscript(index: Int) -> DittoDocumentIDPath { get }
Parameters
index
The index of the array that you wish to access in the key previously specified with the preceding subscripting.
Return Value
The same
DittoDocumentIDPath
object with the provided index incorporated into the document ID path.

Returns the value at the previously specified key in the document ID as an
Any?
. It will benil
if no value exists.Declaration
Swift
public var value: Any? { get }
-
Returns the value at the previously specified key in the document ID as a
String
if possible, otherwise the return value will benil
.Declaration
Swift
public var string: String? { get }

-
Returns the value at the previously specified key in the document ID as an
Int
if possible, otherwise the return value will benil
.Declaration
Swift

-
Returns the value at the previously specified key in the document ID as a
UInt
if possible, otherwise the return value will benil
.Declaration
Swift

-
Returns the value at the previously specified key in the document ID as an
Array<Any?>
if possible, otherwise the return value will benil
.Declaration
Swift
public var array: [Any?]? { get }

Returns the value at the previously specified key in the document ID as an
Array<Any?>
. If the key was invalid the return value will be an empty array.Declaration
Swift

-
Returns the value at the previously specified key in the document ID as a
Dictionary<String, Any?>
if possible, otherwise the return value will benil
.Declaration
