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As of Version 12.1, RemoveProperty has been superseded by AnnotationDelete.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

And from edges:

Vertex Properties  (1)

Set several properties for a graph:

Remove vertex properties including VertexStyle:

VertexLabels:

VertexSize:

VertexShape:

VertexShapeFunction:

A custom property:

Properties & Relations  (6)

Use Property as a wrapper to specify properties in functions such as Graph:

Use PropertyValue to extract values:

For undefined properties, the value $Failed is returned:

Use PropertyValue to set properties in a graph:

The original graph has changed:

Use PropertyValue to unset properties in a graph:

The original graph has changed:

Use PropertyList to test for the presence of a property:

Generate a list of vertex label rules:

Use SetProperty to set a property without changing the original:

The original graph is unchanged:

Possible Issues  (1)

PropertyValue is typically faster than RemoveProperty:
