DittoDocumentPath

class 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.

Properties

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.
docID	`val docID: String`
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.
path	`var path: String`
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: Map<String, Any>`

Functions

get

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.

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.
