Class UnavailableFactoryException

Object

Throwable

Exception

FactoryException

MissingFactoryResourceException

UnavailableFactoryException

All Implemented Interfaces:

Serializable

public class UnavailableFactoryException
extends MissingFactoryResourceException

Thrown when a whole factory can not be created because a resource is missing. The most common case is when the EPSGFactory has no connection to an EPSG database.

Relationship with other exceptions

This exception means that the whole factory is unusable. By contrast, Missing­Factory­Resource­Exception means that at least one particular object can not be created, but other objects may be okay.

0.7

Constructor Detail

UnavailableFactoryException

public UnavailableFactoryException()

Construct an exception with no detail message.

UnavailableFactoryException

public UnavailableFactoryException(String message)

Construct an exception with the specified detail message.

Parameters:

message - the detail message. The detail message is saved for later retrieval by the Throwable.get­Message() method.

UnavailableFactoryException

public UnavailableFactoryException(String message,
                                   Throwable cause)

Construct an exception with the specified detail message and cause. The cause is the exception thrown in the underlying database (e.g. IOException or SQLException).

Parameters:

message - the detail message. The detail message is saved for later retrieval by the Throwable.get­Message() method.

cause - the cause for this exception. The cause is saved for later retrieval by the Throwable.get­Cause() method.

Method Detail

setUnavailableFactory

public void setUnavailableFactory(AuthorityFactory factory)

Specifies which factory is unavailable. This information can be provided when the exception occurred at some later stage after the factory construction (never inside the factory constructor), for example the first time that the factory tried to create an object.

Example: EPSGFactory may have been successfully created with a valid Data­Source. But the call to Data­Source.get­Connection() happens only later (the first time that user invokes a method requiring a search in the database). In case of failure to connect to the database, user may discover late that the factory is actually unavailable. User may want to be informed about which factory is unavailable, for example in order to remove it from the list of factory managed by Multi­Authorities­Factory.

Parameters:

factory - the factory which is unavailable.

getUnavailableFactory

public AuthorityFactory getUnavailableFactory()

Returns the factory which has been found unavailable, or null if unspecified. See set­Unavailable­Factory(Authority­Factory) for more details.

Returns:

the factory that should be considered as unavailable.
