public class DefaultConcatenatedOperation

extends AbstractCoordinateOperation

implements org.opengis.referencing.operation.ConcatenatedOperation

An ordered sequence of two or more single coordinate operations. The sequence of operations is constrained by the requirement that the source coordinate reference system of step (n+1) must be the same as the target coordinate reference system of step (n). The source coordinate reference system of the first step and the target coordinate reference system of the last step are the source and target coordinate reference system associated with the concatenated operation.

Constructor Detail

DefaultConcatenatedOperation

public DefaultConcatenatedOperation(java.lang.String name,
                                    org.opengis.referencing.operation.CoordinateOperation[] operations)

Constructs a concatenated operation from the specified name.

Parameters:

name - The operation name.

operations - The sequence of operations.

DefaultConcatenatedOperation

public DefaultConcatenatedOperation(java.util.Map properties,
                                    org.opengis.referencing.operation.CoordinateOperation[] operations)

Constructs a concatenated 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".

operations - The sequence of operations.

DefaultConcatenatedOperation

public DefaultConcatenatedOperation(java.util.Map properties,
                                    org.opengis.referencing.operation.CoordinateOperation[] operations,
                                    org.opengis.referencing.operation.MathTransformFactory factory)
                             throws org.opengis.referencing.FactoryException

Constructs a concatenated operation from a set of properties and a math transform factory. The properties given in argument follow the same rules than for the AbstractCoordinateOperation constructor.

Parameters:

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

operations - The sequence of operations.

factory - The math transform factory to use for math transforms concatenation.

Throws:

org.opengis.referencing.FactoryException - if the factory can't concatenate the math transforms.

Method Detail

getOperations

public java.util.List getOperations()

Returns the sequence of operations.

Specified by:

getOperations in interface org.opengis.referencing.operation.ConcatenatedOperation

equals

public boolean equals(AbstractIdentifiedObject object,
                      boolean compareMetadata)

Compare this concatenated operation with the specified object for equality. If is , then all available properties are compared including valid area and scope.

Overrides:

equals in class AbstractCoordinateOperation

Parameters:

object - The object to compare to .

compareMetadata - for performing a strict comparaison, or for comparing only properties relevant to transformations.

Returns:

if both objects are equal.

hashCode

public int hashCode()

Returns a hash code value for this concatenated operation.

Overrides:

hashCode in class AbstractCoordinateOperation
