Constructor Detail

DefaultDriver

protected DefaultDriver(String name,
                        String description,
                        String title,
                        EnumSet<Driver.DriverCapabilities> driverCapabilities,
                        Hints implementationHints)

Method Detail

getName

public String getName()

Description copied from interface: Driver

Unique name (non human readable) that can be used to refer to this implementation.

While the Title and Description will change depending on the users local this name will be consistent.

Please note that a given file may be readable by several Drivers (the description of each implementation should be provided to the user so they can make an intellegent choice in the matter).

Specified by:

getName in interface Driver

Returns:

name of this Driver

getTitle

public InternationalString getTitle()

Description copied from interface: Driver

Human readable title for this Driver.

Specified by:

getTitle in interface Driver

Returns:

human readable title for presentation in user interfaces

getImplementationHints

public Map<RenderingHints.Key,?> getImplementationHints()

Implementation hints provided during construction.

Often these hints are configuration and factory settings used to intergrate the driver with application services.

Specified by:

getImplementationHints in interface Factory

Returns:

The map of hints, or an empty map if none.

getDescription

public InternationalString getDescription()

Description copied from interface: Driver

Describe the nature of this Driver implementation.

A description of this Driver type; the description should indicate the format or service being made available in human readable terms.

Specified by:

getDescription in interface Driver

Returns:

A human readable description that is suitable for inclusion in a list of available Drivers.

Throws:

IOException

getDriverCapabilities

public EnumSet<Driver.DriverCapabilities> getDriverCapabilities()

Specified by:

getDriverCapabilities in interface Driver

isAvailable

public boolean isAvailable()

Description copied from interface: Driver

Test to see if this Driver is available, if it has all the appropriate dependencies (jars or libraries).

One may ask how this is different than #canConnect(Map), and basically available can be used by finder mechanisms to list available Drivers.

Specified by:

isAvailable in interface Driver

Specified by:

isAvailable in interface OptionalFactory

Returns:

true if and only if this factory has all the appropriate dependencies on the classpath to create DataStores.
