Operator (Geotools modules 31-SNAPSHOT API)

All Known Subinterfaces:

FunctionName, SpatialOperator, TemporalOperator

All Known Implementing Classes:

FunctionNameImpl, OperatorImpl, SpatialOperatorImpl, 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.
