Firebase.Database.MutableData

Instances of this class encapsulate the data and priority at a location.

Summary

Instances of this class encapsulate the data and priority at a location. It is used in transactions, and it is intended to be inspected and then updated to the desired data at that location.

Note that changes made to a child MutableData instance will be visible to the parent and vice versa.

Properties
`Children`	`IEnumerable< MutableData >` Used to iterate over the immediate children at this location
`ChildrenCount`	`long` The number of immediate children at this location.
`HasChildren`	`bool` True if the data at this location has children, false otherwise.
`Key`	`string` The key name of this location, or null if it is the top-most location.
`Priority`	`object` Gets the current priority at this location.
`Value`	`object` getValue() returns the data contained in this instance as native types.

Public functions
`Child(string path)`	`MutableData` Used to obtain a MutableData instance that encapsulates the data and priority at the given relative path.
`Equals(object o)`	`override bool` Two MutableData are considered equal if they contain the same references and priority.
`GetHashCode()`	`override int` Overriden to ensure two objects that are Equal have the same hash.
`HasChild(string path)`	`bool` Determines if data exists at the given path.
`ToString()`	`override string` Representation of the mutable data as a string containing a key, value pair.

Properties

Children

IEnumerable<MutableData>Children

Used to iterate over the immediate children at this location

Details
Returns	The immediate children at this location

ChildrenCount

longChildrenCount

The number of immediate children at this location.

HasChildren

boolHasChildren

True if the data at this location has children, false otherwise.

Key

stringKey

The key name of this location, or null if it is the top-most location.

Priority

objectPriority

Gets the current priority at this location.

Gets the current priority at this location. The possible return types are:

Double
String

Note that null is allowed

Details
Returns	The priority at this location as a native type

Value

objectValue

getValue() returns the data contained in this instance as native types.

getValue() returns the data contained in this instance as native types. The possible types returned are:

bool
string
long
double
IDictionary{string, object}
List{object} This list is recursive; the possible types for object in the above list is given by the same list. These types correspond to the types available in JSON.

Details
Returns	The data contained in this instance as native types

Public functions

Child

MutableDataChild(stringpath)

Used to obtain a MutableData instance that encapsulates the data and priority at the given relative path.

Details

Parameters

path

A relative path

Returns

An instance encapsulating the data and priority at the given path

Equals

overrideboolEquals(objecto)

Two MutableData are considered equal if they contain the same references and priority.

GetHashCode

overrideintGetHashCode()

Overriden to ensure two objects that are Equal have the same hash.

HasChild

boolHasChild(stringpath)

Determines if data exists at the given path.

Details

Parameters

path

A relative path

Returns

True if data exists at the given path, otherwise false

ToString

overridestringToString()

Representation of the mutable data as a string containing a key, value pair.
