IEdge Interface

An Edge links two vertices. Along with its key/value properties, an edge has both a directionality and a label. The directionality determines which vertex is the tail vertex (out vertex) and which vertex is the head vertex (in vertex). The edge label determines the type of relationship that exists between the two vertices. Diagrammatically, outVertex ---label---> inVertex.

public interface IEdge : IElement, IDictionary<string, Object>, 
	ICollection<KeyValuePair<string, Object>>, IEnumerable<KeyValuePair<string, Object>>, 
	IEnumerable, IDictionary, ICollection

The IEdge type exposes the following members.

Public propertyLabel
Return the label associated with the edge.
Public methodGetVertex
Return the tail/out or head/in vertex. ArgumentException is thrown if a direction of both is provided
Extension Methods
Public Extension MethodAreEqual
A standard method for determining if two elements are equal. This method should be used by any Element.equals() implementation to ensure consistent behavior.
(Defined by ElementHelpers.)
Public Extension MethodCopyProperties
Copy the properties (key and value) from one element to another. The properties are preserved on the from element. ElementPropertiesRule that share the same key on the to element are overwritten.
(Defined by ElementHelpers.)
Public Extension MethodEdgeString (Defined by StringFactory.)
Public Extension MethodGetProperties
Get a clone of the properties of the provided element. In other words, a HashMap is created and filled with the key/values of the element's properties.
(Defined by ElementHelpers.)
Public Extension MethodHaveEqualIds
Simply tests if the element ids are equal().
(Defined by ElementHelpers.)
Public Extension MethodHaveEqualProperties
Determines whether two elements have the same properties. To be true, both must have the same property keys and respective values must be equals().
(Defined by ElementHelpers.)
Public Extension MethodRelabelEdge
An edge is relabeled by creating a new edge with the same properties, but new label. Note that an edge is deleted and an edge is added.
(Defined by EdgeHelpers.)
Public Extension MethodSetProperties(IDictionaryString, Object)Overloaded.
Set the properties of the provided element using the provided dictionary.
(Defined by ElementHelpers.)
Public Extension MethodSetProperties(Object)Overloaded.
Set the properties of the provided element using the provided key value pairs. The var args of Objects must be divisible by 2. All odd elements in the array must be a string key.
(Defined by ElementHelpers.)
Public Extension MethodValidateProperty
Determines whether the property key/value for the specified element can be legally set. This is typically used as a pre-condition check prior to setting a property. Throws ArgumentException whether the triple is legal and if not, a clear reason message is provided
(Defined by ElementHelpers.)
