EAttributes
#############
**alias** (EString)
     Defines the alias of this element to make it available for nested objects.

**autoColor** (EBoolean)
     Defines whether this edge should be automatically color based on its color namespace and EOQ object id.

**className** (EString)
     .. deprecated:: 0.3.0

     @deprecated 
     (deprecated) Specifies the class name of the referred object.

**color** (EString)
     Defines the color that should be used for displaying this edge given as a hex string or html color name.

**colorNamespace** (EString)
     Defines the color namespace this object uses when auto-coloring is activated. The color namespace uniquely maps EOQ object id to a color.

**curved** (EBoolean)
     This attribute is undocumented.

**documentation** (EString)
     Text documentation for the displayable object.

**id** (EString)
     Defines a unique id to identify the displayable object.

**isDeletable** (EBoolean)
     Defines whether the object is movable by the user.

**isMovable** (EBoolean)
     Defines whether the object is movable by the user.

**name** (EString)
     Defines the name of the displayable object

**nsURI** (EString)
     .. deprecated:: 0.3.0

     @deprecated 
     (deprecated) Specifies the namespace URI of the referred object.

**queryStr** (EString)
     Defines the query string used for searching the object.

**queryTarget** (:doc:`Target <./EENum_common_Target>`)
     Defines the target the query should be applied to. Available targets are specified by the Target EENum in the common package.

**queryTargetAlias** (EString)
     References the target by alias. The target alias is only used if a CUSTOM query target is selected. You can only use an alias that already exists. Existing aliases are all aliases of objects that this object is nested in.

**strokeWidth** (EInt)
     Defines the width of the displayed edge.

**type** (:doc:`EdgeType <./EENum_common_EdgeType>`)
     Defines the type of the edge. Types influence the directionality of the edge and the multiplicity of anchors that are used to span the edge.


EReferences
#############
**anchors** (:doc:`Anchor <./EClass_displayableObjects_Anchor>`) (lowerBound=0, upperBound=-1) (containment)
     Defines the anchors which are used to display the edge.

**containers** (:doc:`Container <./EClass_displayableObjects_Container>`) (lowerBound=0, upperBound=-1) (containment)
     Defines the containers that should be displayed for the edge.

**onDeletion** (:doc:`CompoundCmd <./EClass_common_CompoundCmd>`) (lowerBound=0, upperBound=1) (containment)
     This reference is undocumented.

**refersTo** (:doc:`ModelReference <./EClass_common_ModelReference>`) (lowerBound=0, upperBound=1) (containment)
     .. deprecated:: 0.3.0

     @deprecated
     Specifies the model reference. - can this be removed? 
     Not relevant anymore, the query is everything that counts. Add a {@CLASSNAME=...} to the query to filter
