| DatabaseConfiguration | | public DatabaseConfiguration(DataSource datasource, String table, String nameColumn, String keyColumn, String valueColumn, String name)(Code) | | Build a configuration from a table containing multiple configurations.
Parameters:
datasource - the datasource to connect to the database
Parameters:
table - the name of the table containing the configurations
Parameters:
nameColumn - the column containing the name of the configuration
Parameters:
keyColumn - the column containing the keys of the configuration
Parameters:
valueColumn - the column containing the values of the configuration
Parameters:
name - the name of the configuration |
| DatabaseConfiguration | | public DatabaseConfiguration(DataSource datasource, String table, String keyColumn, String valueColumn)(Code) | | Build a configuration from a table.-
Parameters:
datasource - the datasource to connect to the database
Parameters:
table - the name of the table containing the configurations
Parameters:
keyColumn - the column containing the keys of the configuration
Parameters:
valueColumn - the column containing the values of the configuration |
| addProperty | | public void addProperty(String key, Object value)(Code) | | Adds a property to this configuration. This implementation will
temporarily disable list delimiter parsing, so that even if the value
contains the list delimiter, only a single record will be written into
the managed table. The implementation of getProperty()
will take care about delimiters. So list delimiters are fully supported
by DatabaseConfiguration, but internally treated a bit
differently.
Parameters:
key - the key of the new property
Parameters:
value - the value to be added |
| addPropertyDirect | | protected void addPropertyDirect(String key, Object obj)(Code) | | Adds a property to this configuration. If this causes a database error,
an error event will be generated of type EVENT_ADD_PROPERTY
with the causing exception. The event's propertyName is
set to the passed in property key, the propertyValue
points to the passed in value.
Parameters:
key - the property key
Parameters:
obj - the value of the property to add |
| clear | | public void clear()(Code) | | Removes all entries from this configuration. If this causes a database
error, an error event will be generated of type
EVENT_CLEAR with the causing exception. Both the
event's propertyName and the propertyValue
will be undefined.
|
| clearProperty | | public void clearProperty(String key)(Code) | | Removes the specified value from this configuration. If this causes a
database error, an error event will be generated of type
EVENT_CLEAR_PROPERTY with the causing exception. The
event's propertyName will be set to the passed in key, the
propertyValue will be undefined.
Parameters:
key - the key of the property to be removed |
| containsKey | | public boolean containsKey(String key)(Code) | | Checks whether this configuration contains the specified key. If this
causes a database error, an error event will be generated of type
EVENT_READ_PROPERTY with the causing exception. The
event's propertyName will be set to the passed in key, the
propertyValue will be undefined.
Parameters:
key - the key to be checked a flag whether this key is defined |
| getConnection | | protected Connection getConnection() throws SQLException(Code) | | Returns a Connection object. This method is called when
ever the database is to be accessed. This implementation returns a
connection from the current DataSource.
the Connection object to be used
throws:
SQLException - if an error occurs

| getDatasource | | public DataSource getDatasource()(Code) | | Returns the used DataSource object.

| getKeys | | public Iterator getKeys()(Code) | | Returns an iterator with the names of all properties contained in this
configuration. If this causes a database
error, an error event will be generated of type
EVENT_READ_PROPERTY with the causing exception. Both the
event's propertyName and the propertyValue
will be undefined.
an iterator with the contained keys (an empty iterator in caseof an error) |
| getProperty | | public Object getProperty(String key)(Code) | | Returns the value of the specified property. If this causes a database
error, an error event will be generated of type
EVENT_READ_PROPERTY with the causing exception. The
event's propertyName is set to the passed in property key,
the propertyValue is undefined.
Parameters:
key - the key of the desired property the value of this property |
| isEmpty | | public boolean isEmpty()(Code) | | Checks if this configuration is empty. If this causes a database error,
an error event will be generated of type EVENT_READ_PROPERTY
with the causing exception. Both the event's propertyName
and propertyValue will be undefined.
a flag whether this configuration is empty. |
