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.

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.

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

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.
