ObjectPath is a utility class which allows you to retreive/set object path properties on dynamic and typed objects.
Paths
Let's say you have an object, it could be a typed object, or dynamic object or even a dictionary.
ObjectPath allows you to dynamically navigate the object hierachy using a string path expression.
For example:
if(ObjectPath.TryGetValue<int>("x.y.z",outvarval)){// use val is a int}
Methods
Methods
Description
HasValue(obj, path)
returns true if the path can be evaluated against obj
GetPathValue<T>(obj, path)
returns the result of evaluating path as T if it exists, or throws if the path doesn't
TryGetValueValue<T>(obj, path, out T)
retruns the result of valuating the path if it exists
SetPathValue(obj, path, val)
sets the path to a given value
RemovePathValue(obj, path)
removes the leaf of path (for dynamic objects) or resets it to default for typed objects
GetProperties(obj)
enumerates public properties for objects/dictionaries/dynamic objects
ForEachProperty(obj, action)
calls action with each public properties for objects/dictionaries/dynamic objects
ContainsProperty(obj, prop)
shallow inspection to see if current object has a property/value named prop
Clone<T>(obj)
creates a deep clone of public properties and all of it's children
Merge<T>(startObj, overlayObj)
creates a new object which is clone of startObj with any properties defined on overlayObj merged over it
Assign<T>(startObj, overlayObj)
creates a new object which is clone of startObj with any properties defined on overlayObj merged over it
MapValueTo<T>(obj)
coercices an object to a given type.
Examples
vardyn=new{X=13,Y=new{Z="15"}};ObjectPath.GetPathValue(dyn,"X");==>13ObjectPath.GetPathValue(dyn,"X.Y.Z");==>"15"ObjectPath.GetPathValue<int>(dyn,"X.Y.Z");==>15ObjectPath.HasPathValue(dyn,"X.Y")==> true
ObjectPath.HasPathValue(dyn,"X.FOO")==> false
// you can set path values without having to check sub parts, it will use JTokens to build the path.ObjectPath.SetPathValue(dyn,"X.FOO.Zoo","hello");ObjectPath.HasPathValue(dyn,"X.FOO")==> true
ObjectPath.GetPathValue(dyn,"X.FOO.Zoo")==>"hello"
etc
