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
|
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)
|
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.
|

|
ChildrenCount
long ChildrenCount
The number of immediate children at this location.
HasChildren
bool HasChildren
True if the data at this location has children, false otherwise.
Key
string Key
The key name of this location, or null if it is the top-most location.
Priority

Gets the current priority at this location. The possible return types are:
Note that null is allowed
| Details |
|
Returns
|
The priority at this location as a native type

Value
object Value
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.
