IReactPropertyBag
Kind: interface
IReactPropertyBag provides a thread-safe property storage.
Properties are identified by an instance of IReactPropertyName. It is expected that there will be no direct use of this interface. Ideally, all usage should happen through strongly-typed accessors.
Methods
CopyFrom
void CopyFrom(IReactPropertyBag other)
Copies the properties from another property bag
Get
Object Get(IReactPropertyName name)
Gets value of the name property.
It returns null if the property does not exist.
GetOrCreate
Object GetOrCreate(IReactPropertyName name, ReactCreatePropertyValue createValue)
Gets or creates value of the name property.
If the property exists, then the method returns its value. If the property does not exist, then this method creates it by calling the createValue delegate.
The function may return null if the createValue returns null when called. The createValue is called outside of any locks. It is possible that createValue result is not used when another thread sets the property value before the created value is stored.
Set
Object Set(IReactPropertyName name, Object value)
Sets property name to value.
It returns the previously-stored property value. It returns null if the property did not exist.
If the new value is null, then the property is removed.
