availableAdaptorNames
Returns an array of EOAdaptor frameworks found in the standard framework locations. If an adaptor is found in multiple locations the name is listed only once. An adaptor framework is recognized the the "EOAdaptor.framework" suffix. The framework name without this suffix is the name returned in the array.

isDroppedConnectionException:
exception
Returns `YES` if the exception is one that the adaptor can attempt to recover from by reconnecting. `NO` otherwise. The default implementation returns `NO`. Subclasses that support database reconnection should override this to allow for automatic database reconnection.

Description forthcoming.
administrativeConnectionDictionaryForAdaptor:
adaptor
Subclasses should implement this method to return a connection dictionary for an administrative user able to create databases etc. Or `nil` if the the user cancels.

Software documentation for the EOAdaptor(EOAdaptorLoginPanel) category
EOAccess/EOAdaptor.h
Description forthcoming.
runLoginPanel
Invokes [EOLoginPanel -runPanelForAdaptor:validate:allowsCreation:] for the adaptor's +sharedLoginPanelInstance, with `YES` as the validate flag. Returns the dictionary without changing the recievers connection dictionary. Subclass shouldn't need to override this method, yet if the do, they should call this implementation.
runLoginPanelAndValidateConnectionDictionary
Invokes [EOLoginPanel -runPanelForAdaptor:validate:allowsCreation:] for the adaptor's +sharedLoginPanelInstance, with `YES` as the validate flag. If the user supplies valid connection information, the reciever's connection dictionary is updated, and the method return `YES`. Otherwise it returns `NO`. Subclass shouldn't need to override this method, yet if the do, they should call this implementation.
Software documentation for the EOAdaptor(EOExternalTypeMapping) category
EOAccess/EOAdaptor.h
Description forthcoming.
assignExternalInfoForAttribute:
attribute
Invokes [+assignExternalTypeForAttribute:] and unless the attribute is derived it sets the column name if it hasn't been set. An 'attributeName' result in a column named 'ATTRIBUTE_NAME'.
NOTE: This differs from the EOF implementation as EOF unconditionally sets the the external name attributes that are not derived. This can cause trouble on certain RDMS which may not support the extended names used internally in an application. Subclass shouldn't need to override this method, yet if the do, they should call this implementation.
assignExternalInfoForEntireModel:
model
Invokes [+assignExternalInfoForEntity:] for each of the model's entities. Subclass shouldn't need to override this method, yet if the do, they should call this implementation.
assignExternalInfoForEntity:
entity
Invokes [+assignExternalInfoForAttribute:] for each of the model's entities. If the externalName of the entity hasn't been set, this method sets it to a standardized name according to the entities name. An 'entityName' will be converted to 'ENTITY_NAME'.
Subclass shouldn't need to override this method, yet if the do, they should call this implementation.
assignExternalTypeForAttribute:
attribute
Subclasses must override this method without invoking this implementation to set the the external type according to the internal type information. It should take into account width, precesion and scale accordingly.
externalTypesWithModel:
model
Subclasses must override this method without invoking this implementation to return an array of types available for the RDBMS. A subclass may use information provided by an optional model to determine the exact available types.
internalTypeForExternalType:
extType
model:
model
Subclasses must override this method without invoking this implementation to return the name of the class used internal to the database for the extType provided. A subclass may use information provided by an optional model to determine the exact type.
