RemoveProperty

As of Version 12.1, RemoveProperty has been superseded by AnnotationDelete.

✖
RemoveProperty[{obj,itemspec}]

removes all properties associated with itemspec in obj.

✖
RemoveProperty[{obj,itemspec},name]

removes the property name associated with itemspec in obj.

Details

  • Properties are used to store and manipulate name->value pairs for specific named items within an object such as Graph, MeshRegion, and BoundaryMeshRegion.
  • RemoveProperty will produce an object with the specified property removed.
  • The item specification itemspec typically has the form {collection,index}.
  • 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 standard properties, RemoveProperty effectively resets the value to the property default value.
  • Objects that support properties include Graph, MeshRegion, and BoundaryMeshRegion. Item specifications for each type of object is given in their reference pages.
