public static <T> DbAction.Insert<T> insert(T entity,
                                            JdbcPropertyPath propertyPath,

public static <T> DbAction.Update<T> update(T entity,
                                            JdbcPropertyPath propertyPath,
                                            DbAction dependingOn)

delete

public static <T> DbAction.Delete<T> delete(Object id,
                                            Class<T> type,
                                            T entity,
                                            JdbcPropertyPath propertyPath,
                                            DbAction dependingOn)

deleteAll

public static <T> DbAction.DeleteAll<T> deleteAll(Class<T> type,
                                                  JdbcPropertyPath propertyPath,
                                                  DbAction dependingOn)

doExecuteWith

protected abstract void doExecuteWith(Interpreter interpreter)

Executing this DbAction with the given Interpreter without any exception handling.

Parameters:

interpreter - the Interpreter responsible for actually executing the DbAction.

toString

@Generated(value="lombok")
public String toString()

Overrides:

toString in class Object

getEntityType

@Generated(value="lombok")
public Class<T> getEntityType()

Class of the entity of which the database representation is affected by this action.

getEntity

@Generated(value="lombok")
public T getEntity()

The entity of which the database representation is affected by this action. Might be null.

getPropertyPath

@Generated(value="lombok")
public JdbcPropertyPath getPropertyPath()

The path from the Aggregate Root to the entity affected by this DbAction.

getAdditionalValues

@Generated(value="lombok")
public Map<String,Object> getAdditionalValues()

Key-value-pairs to specify additional values to be used with the statement which can't be obtained from the entity, nor from DbActions this depends on. A used case are map keys, which need to be persisted with the map value but aren't part of the value.

getDependingOn

@Generated(value="lombok")
public DbAction getDependingOn()

Another action, this action depends on. For example the insert for one entity might need the id of another entity, which gets insert before this one. That action would be referenced by this property, so that the id becomes available at execution time. Might be null.
