DittoDocumentPath

Provides an interface to specify a path to a key in a document that you can then call a function on to get the value at the specified key as a specific type. You obtain a DittoDocumentPath by subscripting a DittoDocument and you can then further subscript a DittoDocumentPath to further specify the key of the document that you want to get the value of.

Parameters

docHandleWrapper

A wrapper around the Rust document pointer.

path

The initial path into the DittoDocument. Given that all DittoDocuments are maps at the top level, initialPath should only ever be a string key into the top level map. Multiple path components are not supported via this constructor (i.e. "key[0]" or "key.nextKey" are invalid). Further levels of paths should be added via repeated subscripting on the returned DittoDocumentPath (i.e. doc["key"][0] or doc["key"]["nextKey"]).

Properties

attachmentToken

val attachmentToken: DittoAttachmentToken?

Returns the value at the previously specified key in the document as a DittoAttachmentToken. If the key was invalid the return value will be null.

boolean

val boolean: Boolean?

Returns the value at the previously specified key in the document as a Boolean if possible, otherwise the return value will be null.

booleanValue

val booleanValue: Boolean

Returns the value at the previously specified key in the document as a Boolean. If the key was invalid the return value will be false.

counter

val counter: DittoCounter?

Returns the value at the previously specified key in the document as a DittoCounter if possible, otherwise the return value will be null.

double

val double: Double?

Returns the value at the previously specified key in the document as a Double if possible, otherwise the return value will be null.

doubleValue

val doubleValue: Double

Returns the value at the previously specified key in the document as a Double. If the key was invalid the return value will be 0.0.

float

val float: Float?

Returns the value at the previously specified key in the document as a Float if possible, otherwise the return value will be null.

floatValue

val floatValue: Float

Returns the value at the previously specified key in the document as a Float. If the key was invalid the return value will be 0f.

int

val int: Int?

Returns the value at the previously specified key in the document as an Int if possible, otherwise the return value will be null.

intValue

val intValue: Int

Returns the value at the previously specified key in the document as an Int. If the key was invalid the return value will be 0.

list

val list: List<Any?>?

Returns the value at the previously specified key in the document as a List<Any?> if possible, otherwise the return value will be null.

listValue

val listValue: List<Any?>

Returns the value at the previously specified key in the document as a List<Any?>. If the key was invalid the return value will be an empty list.

map

val map: Map<String, Any?>?

Returns the value at the previously specified key in the document as a Map<String, Any?> if possible, otherwise the return value will be null.

mapValue

val mapValue: Map<String, Any?>

Returns the value at the previously specified key in the document as a Map<String, Any?>. If the key was invalid the return value will be an empty dictionary.

val register: DittoRegister?

Returns the value at the previously specified key in the document as a DittoRegister if possible, otherwise the return value will be null.

string

val string: String?

Returns the value at the previously specified key in the document as a String if possible, otherwise the return value will be null.

stringValue

val stringValue: String

Returns the value at the previously specified key in the document as a String. If the key was invalid the return value will be an empty string.

value

val value: Any?

Returns the value at the previously specified key in the document as an Any? if possible, otherwise the return value will be null

Functions

get

operator fun get(index: Int): DittoDocumentPath

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.

operator fun get(key: String): DittoDocumentPath

Used to specify a path to a key in the document that you can subscript further to access a nested key in the document.
