public void boot(boolean create,
                 java.util.Properties properties)
          throws StandardException
```
    Description copied from interface: ModuleControl
    
    Boot this module with the given properties. Creates a module instance that can be found using the findModule() methods of Monitor. The module can only be found using one of these findModule() methods once this method has returned.
    An implementation's boot method can throw StandardException. If it is thrown the module is not registered by the monitor and therefore cannot be found through a findModule(). In this case the module's stop() method is not called, thus throwing this exception must free up any resources.
    When create is true the contents of the properties object will be written to the service.properties of the persistent service. Thus any code that requires an entry in service.properties must explicitly place the value in this properties set using the put method.
    Typically the properties object contains one or more default properties sets, which are not written out to service.properties. These default sets are how callers modify the create process. In a JDBC connection database create the first set of defaults is a properties object that contains the attributes that were set on the jdbc:derby: URL. This attributes properties set has the second default properties set as its default. This set (which could be null) contains the properties that the user set on their DriverManager.getConnection() call, and are thus not owned by Derby code, and thus must not be modified by Derby code.
    When create is false the properties object contains all the properties set in the service.properties file plus a limited number of attributes from the JDBC URL attributes or connection properties set. This avoids properties set by the user compromising the boot process. An example of a property passed in from the JDBC world is the bootPassword for encrypted databases.
    Code should not hold onto the passed in properties reference after boot time as its contents may change underneath it. At least after the complete boot is completed, the links to all the default sets will be removed.
    
    Specified by:
    
    boot in interface ModuleControl
    
    Throws:
    
    StandardException - Module cannot be started.

```
public void stop()
```
    Description copied from interface: ModuleControl
    
    Stop the module. The module may be found via a findModule() method until some time after this method returns. Therefore the factory must be prepared to reject requests to it once it has been stopped. In addition other modules may cache a reference to the module and make requests of it after it has been stopped, these requests should be rejected as well.

```
    Description copied from interface: DataValueFactory
    
    Return the RuleBasedCollator depending on the collation type. If the collation type is UCS_BASIC, then this method will return null. If the collation type is TERRITORY_BASED then the return value will be the Collator derived from the database's locale. If this is the first time Collator is being requested for a database with collation type of TERRITORY_BASED, then we will check to make sure that JVM supports the Collator for the database's locale. If not, we will throw an exception This method will be used when Store code is trying to create a DVD template row using the format ids and the collation types. First a DVD will be constructed just using format id. Then if the DVD is of type StringDataValue, then it will call this method to get the Collator object. If the Collator object returned from this method is null then we will continue to use the default DVDs for the character types, ie the DVDs which just use the JVM's default collation. (This is why, we want this method to return null if we are dealing with UCS_BASIC.) If the Collator object returned is not null, then we will construct collation sensitive DVD for the character types. So, the return value of this method determines if we are going to create a character DVD with default collation or with custom collation.
    
    Specified by:
    
    getCharacterCollator in interface DataValueFactory
    
    Parameters:
    
    collationType - This will be UCS_BASIC or TERRITORY_BASED
    
    Returns:
    
    Collator null if the collation type is UCS_BASIC. Collator based on territory if the collation type is TERRITORY_BASED
    
    Throws:
    
    StandardException

    Verify that JVM has support for the Collator for the database's locale.
    
    Parameters:
    
    strength - Collator strength or -1 for locale default.

    Collator for database's locale

public DataValueDescriptor getNull(int formatId,

                            throws StandardException
```
    Description copied from interface: DataValueFactory
    
    Return an object based on the format id and collation type. For format ids which do not correspond to character types, a format id is sufficient to get the right DVD. But for character types, Derby uses same format id for collation sensitive character types and for character types that use the default JVM collation. To get the correct DVD for character types, we need to know the collation type. Using collation type, we will determine if we need to construct collation sensitive DVD and associate the correct RuleBasedCollator with such DVDs.
    
    Specified by:
    
    getNull in interface DataValueFactory
    
    Parameters:
    
    formatId - Format id for the DVD
    
    collationType - this is meaningful only for character types.
    
    Returns:
    
    DataValueDescriptor which will be constructed using the passed parameters
    
    Throws:
    
    StandardException
    
    See Also:
    
    DataValueFactory.getNull(int, int)
  - getNullDVDWithUCS_BASICcollation
```
public static DataValueDescriptor getNullDVDWithUCS_BASICcollation(int formatId)
```
    This method will return a DVD based on the formatId. It doesn't take into account the collation that should be associated with collation sensitive DVDs, which are all the character type DVDs. Such DVDs returned from this method have default UCS_BASIC collation associated with them. If collation associated should be territory based, then that needs to be handled by the caller of this method. An example of such code in the caller can be seen in DataValueFactory.getNull method.
    
    Parameters:
    
    formatId - Return a DVD based on the format id
    
    Returns:
    
    DataValueDescriptor with default collation of UCS_BASIC
