MutableDocument

expect class MutableDocument : Document(source)

A Couchbase Lite Document. A document has key/value properties like a Map.

actual class MutableDocument : Document(source)

Constructors

expect constructor()

Creates a new Document object with a new random UUID. The created document will be saved into a database when you call the Database's save(Document) method with the document object given.

expect constructor(id: String?)

Creates a new Document with the given ID. If the id is null, the document will be created with a new random UUID. The created document will be saved into a database when you call the Database's save(Document) method with the document object given.

expect constructor(data: Map<String, Any?>)

Creates a new Document with a new random UUID and the map as the content. Allowed value types are List, Date, Map, Number, null, String, Array, Blob, and Dictionary. If present, Lists, Maps and Dictionaries may contain only the above types. The created document will be saved into a database when you call Database.save(Document) with this document object.

expect constructor(id: String?, data: Map<String, Any?>)

Creates a new Document with a given ID and content from the passed Map. If the id is null, the document will be created with a new random UUID. Allowed value types are List, Date, Map, Number, null, String, Array, Blob, and Dictionary. The List and Map must contain only the above types. The created document will be saved into a database when you call the Database's save(Document) method with the document object given.

expect constructor(id: String?, json: String)

Creates a new Document with the given ID and content from the passed JSON string. If the id is null, the document will be created with a new random UUID. The created document will be saved into a database when you call the Database's save(Document) method with the document object given.

Properties

actual

open val actual: CPointer<<Error class: unknown class>>

count

expect val count: Int

The number of the entries in the dictionary.

actual val count: Int

expect val id: String

The document's ID.

actual val id: String

keys

expect val keys: List<String>

A List containing all keys, or an empty List if the document has no properties.

actual val keys: List<String>

revisionID

expect val revisionID: String?

The document's revision id. The revision id in the Document class is a constant while the revision id in the MutableDocument class is not. A newly created Document will have a null revision id. The revision id in a MutableDocument will be updated on save. The revision id format is opaque, which means its format has no meaning and shouldn't be parsed to get information.

actual val revisionID: String?

sequence

expect val sequence: Long

The sequence number of the document in the database. The sequence number indicates how recently the document has been changed. Every time a document is updated, the database assigns it the next sequential sequence number. Thus, when a document's sequence number changes it means that the document been update (on-disk). If one document's sequence is different than another's, the document with the larger sequence number was changed more recently. Sequence numbers are not available for documents obtained from a replication filter. This method will always return 0 for such documents.

actual val sequence: Long

Functions

contains

expect operator fun contains(key: String): Boolean

Tests whether a property exists or not. This can be less expensive than getValue(String), because it does not have to allocate an Object for the property value.

actual operator fun contains(key: String): Boolean

equals

open operator override fun equals(other: Any?): Boolean

get

operator fun Document.get(key: String): Fragment

Subscript access to a Fragment object by key.

operator fun MutableDocument.get(key: String): MutableFragment

Subscripting access to a MutableFragment object that represents the value of the document by key.

getArray

expect open override fun getArray(key: String): MutableArray?

Get a property's value as an Array, which is a mapping object of an array value. Returns null if the property doesn't exist, or its value is not an array.

actual open override fun getArray(key: String): MutableArray?

getBlob

expect fun getBlob(key: String): Blob?

Gets a property's value as a Blob. Returns null if the value doesn't exist, or its value is not a Blob.

actual fun getBlob(key: String): Blob?

open override fun getBlob(key: String): Blob?

getBoolean

expect fun getBoolean(key: String): Boolean

Gets a property's value as a boolean. Returns true if the value exists, and is either true or a nonzero number.

actual fun getBoolean(key: String): Boolean

getDate

expect fun getDate(key: String): Instant?

Gets a property's value as a Date. JSON does not directly support dates, so the actual property value must be a string, which is then parsed according to the ISO-8601 date format (the default used in JSON.) Returns null if the value doesn't exist, is not a string, or is not parsable as a date. NOTE: This is not a generic date parser! It only recognizes the ISO-8601 format, with or without milliseconds.

actual fun getDate(key: String): Instant?

getDictionary

expect open override fun getDictionary(key: String): MutableDictionary?

Get a property's value as a Dictionary, which is a mapping object of a dictionary value. Returns null if the property doesn't exist, or its value is not a dictionary.

actual open override fun getDictionary(key: String): MutableDictionary?

getDouble

expect fun getDouble(key: String): Double

Gets a property's value as a double. Integers will be converted to double. The value true is returned as 1.0, false as 0.0. Returns 0.0 if the property doesn't exist or does not have a numeric value.

actual fun getDouble(key: String): Double

getFloat

expect fun getFloat(key: String): Float

Gets a property's value as a float. Integers will be converted to float. The value true is returned as 1.0, false as 0.0. Returns 0.0 if the value doesn't exist or does not have a numeric value.

actual fun getFloat(key: String): Float

getInt

expect fun getInt(key: String): Int

Gets a property's value as an int. Floating point values will be rounded. The value true is returned as 1, false as 0. Returns 0 if the value doesn't exist or does not have a numeric value.

actual fun getInt(key: String): Int

getLong

expect fun getLong(key: String): Long

getValue

expect fun getValue(key: String): Any?
