Classes that implement IRepresentationRule

Remarks

IRepresentationRule interface provides access to the members of a single representation rule used by a representation class to draw the individual feature representations. A representation rule consists of one or more basic symbol layers namely BasicLineSymbol, BasicFillSymbol and BasicMarkerSymbol. In addition to the symbol layers, a representation rule may also contain geometric effects.

The following code snippet shows how to get access to a RepresentationRule object given with its name. The name of the representation rule can be changed to get access to a different representation rule.

  Dim pRepRules As IRepresentationRules
  Dim pRepRule As IRepresentationRule
  Dim lID As Long, sName As String
  Set pRepRules = pRepClass.RepresentationRules
  'walk through the representationrules and get a specific rule with given name
  pRepRules.Reset
  pRepRules.Next lID, pRepRule
  Do Until pRepRule Is Nothing
      If pRepRules.Name(lID) = "Buildings_Rule" Then Exit Do
      pRepRules.Next lID, pRepRule
  Loop
