KeyGenerator |
createKeyGenerator() |
Create a default key generator instance with the algorithm the factory is
responsible for.
|
KeyGenerator |
createKeyGenerator(KeyGeneratorDef definition) |
Create a key generator instance from the given definition with the algorithm the
factory is responsible for.
|
java.lang.String |
getAlgorithmName() |
Get name of key generator algorithm.
|
boolean |
hasMandatoryParameters() |
Does the algorithm has mandatory parameters and therefore requires a key generator
definition in mapping file?
|
abstract void |
toCreateDDL(KeyGenerator key,
DDLWriter writer) |
Generate create script for given SEQUENCE key generator.
|
abstract void |
toDropDDL(KeyGenerator key,
DDLWriter writer) |
Generate drop script for given SEQUENCE key generator.
|
protected java.lang.String |
toPrimaryKeyList(Table table) |
Build a string containing names of all primary key columns separated by '_'.
|
protected java.lang.String |
toPrimaryKeyTypeList(Table table) |
Build a string containing types of all primary key columns separated by '_'.
