Class AbstractFactory

java.lang.Object
  org.geotools.factory.AbstractFactory
      org.geotools.referencing.factory.AbstractFactory

All Implemented Interfaces:

Factory, org.opengis.referencing.Factory, javax.imageio.spi.RegisterableService

Direct Known Subclasses:

AbstractAuthorityFactory, AbstractCoordinateOperationFactory, DatumAliases, GeotoolsFactory

public class AbstractFactory

extends AbstractFactory

implements org.opengis.referencing.Factory

Base class for all factories in the referencing module. Factories can be grouped in two categories:

• Authority factories creates objects from a compact string defined by an authority.
• Object factories allows applications to make objects that cannot be created by an authority factory. This factory is very flexible, whereas the authority factory is easier to use.

Field Detail

LOGGER

public static final java.util.logging.Logger LOGGER

The logger for event related to Geotools's factories.

Constructor Detail

AbstractFactory

protected AbstractFactory()

Constructs a factory with the default priority.

AbstractFactory

protected AbstractFactory(int priority)

Constructs a factory with the specified priority.

Parameters:

priority - The priority for this factory, as a number between MINIMUM_PRIORITY and MAXIMUM_PRIORITY inclusive.

Method Detail

getVendor

public org.opengis.metadata.citation.Citation getVendor()

Returns the vendor responsible for creating this factory implementation. Many implementations may be available for the same factory interface. The default implementation returns Geotools.

Specified by:

getVendor in interface org.opengis.referencing.Factory

Returns:

The vendor for this factory implementation.

ensureNonNull

protected static void ensureNonNull(java.lang.String name,
                                    java.lang.Object object)
                             throws java.lang.IllegalArgumentException

Makes sure that an argument is non-null. This is a convenience method for subclass methods.

Parameters:

name - Argument name.

object - User argument.

Throws:

org.opengis.parameter.InvalidParameterValueException - if is null.

java.lang.IllegalArgumentException
