PropertyList

PropertyList[{obj,itemspec}]
lists the properties available for itemspec in obj.

DetailsDetails

  • Properties are used to store and manipulate pairs for specific named items within an object such as Graph.
  • The item specification itemspec typically has the form .
  • The index can typically have the following forms:
  • inda single index
    {ind1,ind2,}a list of indexes
    Allall possible indexes in collection
    pattindexes that match patt in collection
  • The collection can typically have the following forms:
  • cola single collection
    {col1,col2,}a list of collections
    Allall possible collections
    pattcollections that match patt
  • The item specification itemspec of the form collection refers to the default value for all indexes in the collection.
  • For an item specification itemspec that refers to more than a single item, PropertyList will give the union of properties for the different items.
  • The items available for Graph objects include vertices and edges.
