DatumValidator

public class DatumValidator
extends ReferencingValidator

Validates Datum and related objects from the org.opengis.datum package.

This class is provided for users wanting to override the validation methods. When the default behavior is sufficient, the Validators static methods provide a more convenient way to validate various kinds of objects.

2.2

Constructor Details

DatumValidator

public DatumValidator(ValidatorContainer container)

Creates a new validator instance.

Parameters:

container - the set of validators to use for validating other kinds of objects (see field javadoc).

Method Details

dispatch

public int dispatch(Datum object)

For each interface implemented by the given object, invokes the corresponding validate(…) method defined in this class (if any).

Parameters:

object - the object to dispatch to validate(…) methods, or null.

Returns:

number of validate(…) methods invoked in this class for the given object.

validate

public void validate(PrimeMeridian object)

Validates the given prime meridian.

Parameters:

object - the object to validate, or null.

validate

public void validate(Ellipsoid object)

Validates the given ellipsoid. This method checks the following conditions:

• Axis unit is defined and is linear.
• semi-minor <= semi-major.
• inverse flattening > 0.
• Consistency of semi-minor axis length with inverse flattening factor.

Parameters:

object - the object to validate, or null.

validate

public void validate(GeodeticDatum object)

Validates the given datum.

Parameters:

object - the object to validate, or null.

validate

public void validate(VerticalDatum object)

Validates the given datum.

Parameters:

object - the object to validate, or null.

validate

public void validate(TemporalDatum object)

Validates the given datum.

Parameters:

object - the object to validate, or null.

validate

public void validate(ImageDatum object)

Validates the given datum.

Parameters:

object - the object to validate, or null.

validate

public void validate(EngineeringDatum object)

Validates the given datum.

Parameters:

object - the object to validate, or null.
