Method Detail

generateRowProperties

protected Map<String,Object> generateRowProperties(DBEntry entry)

Description copied from class: BaseRowMapper

generates a map that contains all columns mapped to their values, so that the map can be used to store the object into a row. The ID column and the corresponding ID should not be put in there, as this will happen automatically later.

Specified by:

generateRowProperties in class BaseRowMapper<T extends DBEntry>

generateNewID

public Integer generateNewID()
                      throws DatabaseException

Description copied from class: BaseRowMapper

returns the return value of the given IDFactory or throws UnsupportedOperationException if no IDFactory was supplied

Specified by:

generateNewID in interface ObjectRowMapper<T extends DBEntry>

Overrides:

generateNewID in class BaseRowMapper<T extends DBEntry>

Throws:

DatabaseException

DBClassStore.generateNewID(), SQLNumberGenerator, TransactionalNumberGenerator

instantiate

public T instantiate(RowItem row)
                              throws Exception

Description copied from interface: ObjectRowMapper

instantiates the DBEntry based on the properties in the given row. The given row contains all the columns of the queried ResultSet unless the columns to be retrieved are restricted by ObjectRowMapper.getRestrictMappedColumns().

Throws:

Exception
