Interface Operator

All Known Subinterfaces:
ComparisonOperatorType, FunctionName, SpatialOperator, SpatialOperatorType, TemporalOperator
All Known Implementing Classes:
ComparisonOperatorTypeImpl, FunctionNameImpl, OperatorImpl, SpatialOperatorImpl, SpatialOperatorTypeImpl, TemporalOperatorImpl
public interface Operator
Indicates a supported Operator.

The operator that is supported is indicated by the getName() field, these names are formally defined to match:

  • A subclass of Filter. Examples include "BBOX" and "EqualsTo"
  • A subclass of Expression or Function. Examples include "ADD" and "Length"
Each filter subclass has an associated name (such as BBOX or EqualsTo), you can use this name to determine if a matching Operator is defined as part of FilterCapabilities.
