⊟ Remarks

Entities can have URIs, or they can be anonymous, in which case their URI is null. However, in order to construct a blank node, use new SemWeb.BNode().

Specialized stores will attach caching information to Entity objects to make interaction with the store faster. It is therefore better to reuse existing Entity objects where possible.

The == and != operators have been overloaded for entities. Two named entities are equal when they both have the same URI. Two anonymous Entity objects are equal if they were created by the same Store and were assigned the same resource key.

An implicit conversion operator is defined from strings to entities. The operator converts the string to an entity by returning an entity with that URI.

The following examples all create entities.

C# Example

Entity thing1 = new Entity("http://www.example.com/#thing"); Entity thing2 = "http://www.example.com/#thing"; // operator overload Entity thing3 = (Entity)"http://www.example.com/#thing"; // operator overload with explicit cast Console.WriteLine(thing1.Uri)

	SetResourceKey (object, object) Documentation for this section has not yet been entered. (Inherited from Resource.)
static	ValidateUri (string) : string Validates that a string is a legitimate IRI-Reference, i.e. a legitimate URI in RDF.

⊟ Public Operators

⊟ Explicitly Implemented Interface Members

IComparable.CompareTo

This implements the .NET 1.0 IComparable interface method to compare two Resources. The public method Resource.CompareTo(Resource) is also available, and in .NET 2.0 Resource additionally implements IComparable<SemWeb.Resource>. (Inherited from Resource.)
