public <E> E createValue(EntityFactory<E> entityFactory,
                         E value)
Specified by:
createValue in interface EntityEngine

updateValue

public <E> void updateValue(EntityFactory<E> entityFactory,
                            E newValue)
Specified by:
updateValue in interface EntityEngine

execute

public int execute(Update.WhereContext updateContext)
Description copied from interface: EntityEngine
Allows you to execute an UPDATE statement using a fluent interface.

See the Update class for an example.

Specified by:
execute in interface EntityEngine
Parameters:
updateContext - build up a fluent UPDATE statement here. Should start with Update.into(
Returns:
the number of entities / DB rows deleted.

delete

public int delete(Delete.DeleteWhereContext deleteContext)
Description copied from interface: EntityEngine
Allows you to execute an SQL DELETE using a fluent interface.

You should call this using code that looks like:

     entityEngine.delete(Delete.from(Entity.ISSUE_SECURITY_LEVEL).whereIdEquals(securityLevelId));
 
or:
     entityEngine.delete(
         Delete.from(Entity.ISSUE_SECURITY_LEVEL)
               .whereEqual("scheme", schemeId)
               .andEqual("name", name)
     );
 

Specified by:
delete in interface EntityEngine
Parameters:
deleteContext - build up a fluent DELETE statement here. Should start with Delete.from(
Returns:
the number of entities / DB rows deleted.

removeValue

public <E> int removeValue(EntityFactory<E> entityFactory,
                           Long id)
Description copied from interface: EntityEngine
Remove the given entity from the DB.

Specified by:
removeValue in interface EntityEngine
Parameters:
entityFactory - represents the entity type (ie TABLE)
id - the id of the row to delete.
Returns:
number of rows effected by this operation

selectFrom

public <E> EntityEngine.SelectFromContext<E> selectFrom(EntityFactory<E> entity)
Description copied from interface: EntityEngine
Starts a dialog to run a SELECT query against EntityEngine.

e.g. to run "SELECT * FROM remotelink WHERE id = ?" (and return a single entity value) you could write:

   RemoteIssueLink link = entityEngine.selectFrom(Entity.REMOTE_ISSUE_LINK)
                                 .whereEqual("id", remoteIssueLinkId)
                                 .singleValue();
 
e.g. to run "SELECT * FROM remotelink WHERE issueid = ? AND app = ? ORDER BY type" you could write:
   List remoteIssueLinks =
           entityEngine.selectFrom(Entity.REMOTE_ISSUE_LINK)
                       .whereEqual("issueid", issueId)
                       .andEqual("app", app)
                       .orderBy("type");
 

Specified by:
