DBObjLimit

public DBObjLimit(int uid)
           throws DBException
Parameters:
uid - The owner's uid

DBObjLimit

public DBObjLimit(RequestContext request)
           throws DBException
For using DBObjects within Controllers. Initializes based upon the current user and the requested db. [Of course this can be modified later]

Parameters:
request - - The controller request handed to you by the framework.
Throws:
DBException - uppon error
Method Detail

getValidValues

public Vector getValidValues(String fieldName)
                      throws DBException

Overrides:
getValidValues in class DBObject
Parameters:
fieldName - Fielname to retrieve values for
Returns:
Hashtable Value/description pairs for this field
Throws:
DBException - If the values cannot be retrieved

setupFields

public void setupFields()
                 throws DBException
Description copied from class: DBObject
Method to set up the fields for this database object. This method should be defined in the implementing object and should make calls to addField, addKey, setMultiValued, etc. as required to define the content of the DBObject. Each setupFields method should call "super.setupFields()" so that field definitions can be "inheritcable"

Overrides:
setupFields in class DBObject
Throws:
DBException - If there is an error setting up the fields as requested. For example, if a field allowing null is requested as part of the key
See Also:
DBObject.setupFields()

populateDefaultValues

public void populateDefaultValues()
                           throws DBException
Default values for limitations

Overrides:
populateDefaultValues in class DBObject
Throws:
DBException - Upon add error, never if it isn't overridden.

update

public void update()
            throws DBException
Update the database as well as updating the cache size.

Specified by:
