Javadoc

Defines a topological predicate that can be evaluated on Geometry valued objects.

Most used methods

  • getSubType
    Returns the type of spatial operator. Use this to safely determine the subtype of SpatialOperator.
  • getPropName
    Returns the name of the spatial property to be considered.
  • getParam1
    Returns the first spatial parameter.
  • getParams
  • getType
    Always returns Operator.Type#SPATIAL (for SpatialOperator instances).
