public class DefaultOperation

extends DefaultSingleOperation

implements org.opengis.referencing.operation.Operation

A parameterized mathematical operation on coordinates that transforms or converts coordinates to another coordinate reference system. This coordinate operation thus uses an operation method, usually with associated parameter values.

In the Geotools implementation, the parameter values are inferred from the transform. Other implementations may have to overrides the getParameterValues() method.

Constructor Detail

DefaultOperation

public DefaultOperation(java.util.Map properties,
                        org.opengis.referencing.crs.CoordinateReferenceSystem sourceCRS,
                        org.opengis.referencing.crs.CoordinateReferenceSystem targetCRS,
                        org.opengis.referencing.operation.MathTransform transform,
                        org.opengis.referencing.operation.OperationMethod method)

Constructs an operation from a set of properties. The properties given in argument follow the same rules than for the AbstractCoordinateOperation constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

sourceCRS - The source CRS.

targetCRS - The target CRS.

transform - Transform from positions in the source CRS to positions in the target CRS.

method - The operation method.

Returns a coordinate operation of the specified class. This method may constructs instance of Conversion or Transformation among others.

Parameters:

properties - Set of properties. Should contains at least "name".

sourceCRS - The source CRS.

targetCRS - The target CRS.

transform - Transform from positions in the source CRS to positions in the target CRS.

method - The operation method, or .

type - The minimal type as Conversion.class, Projection.class, etc. This method may create an instance of a subclass of .

getMethod

public org.opengis.referencing.operation.OperationMethod getMethod()

Returns the operation method.

Specified by:

getMethod in interface org.opengis.referencing.operation.Operation

getParameterValues

public org.opengis.parameter.ParameterValueGroup getParameterValues()
                                                             throws java.lang.UnsupportedOperationException

Returns the parameter values. The default implementation infer the parameter values from the transform, if possible.

Specified by:

getParameterValues in interface org.opengis.referencing.operation.Operation

equals

public boolean equals(AbstractIdentifiedObject object,
