@Classifier(ABSTRACT)
@UML(identifier="SingleOperation",
     specification=ISO_19111)
public interface SingleOperation
extends CoordinateOperation

A parameterized mathematical operation on coordinates that changes coordinates to another CRS. This coordinate operation thus uses an operation method, usually with associated parameter values. This is a single (not concatenated) coordinate operation.

Since:

Method Details

getMethod

@UML(identifier="method",
     obligation=MANDATORY,
     specification=ISO_19111)
OperationMethod getMethod()

Returns the algorithm or procedure used by this single operation.

Returns:

algorithm or procedure used by this single operation.

getParameterValues

@UML(identifier="parameterValue",
     obligation=OPTIONAL,
     specification=ISO_19111)
ParameterValueGroup getParameterValues()

Returns the parameter values used by this single operation. If the operation has no parameter, then this method shall return an empty group.

Returns:

the parameter values used by this single operation. Never null but may be a group with no parameter.

• OperationMethod.getParameters()

Convenience extension to OGC/ISO standard

The sequence if GeneralParameterValue is replaced by a ParameterValueGroup because it provides method for fetching parameters by their names.
