Method Detail

setConfiguration

public void setConfiguration(com.solarmetric.rd.kodo.impl.jdbc.conf.JDBCConfiguration conf)

Description copied from interface: MappingFactory

Set the configuration for the factory.

Specified by:

setConfiguration in interface MappingFactory

isSingleOperation

public boolean isSingleOperation()

Description copied from interface: MappingFactory

Return true if this factory reads and writes all system mappings at once. Knowing this lets us optimize some operations. If a factory returns true to this method, then it should be able to handle MappingFactory.readMapping(com.solarmetric.rd.kodo.meta.ClassMetaData, com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfoRepository) and MappingFactory.revertMappings(com.solarmetric.rd.kodo.meta.ClassMetaData[]) calls that pass in a null meta data argument.

Specified by:

isSingleOperation in interface MappingFactory

readMapping

public void readMapping(com.solarmetric.rd.kodo.meta.ClassMetaData meta,
                        com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfoRepository repos)

Description copied from interface: MappingFactory

Read the object-relational mapping for the given persistent type and add it to the given repository.

Specified by:

readMapping in interface MappingFactory

Parameters:

meta - the type to read mapping information for

repos - add the mapping information to this repository

storeMappings

public void storeMappings(com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfoRepository mappings,
                          com.solarmetric.rd.kodo.meta.JDOMetaDataRepository repos)

Description copied from interface: MappingFactory

Store any changes made to the given mappings, including their field mappings.

Specified by:

storeMappings in interface MappingFactory

Parameters:

mappings - the changed mappings

repos - can be used to access class metadata if needed

revertMappings

public boolean revertMappings(com.solarmetric.rd.kodo.meta.ClassMetaData[] types)

Description copied from interface: MappingFactory

Revert the mappings to their last saved state, or return false if any cannot be reverted.

Specified by:

revertMappings in interface MappingFactory

Parameters:

types - the types to revert

Returns:

true if all mappings were reverted, false otherwise

dropMappings

public boolean dropMappings(com.solarmetric.rd.kodo.meta.ClassMetaData[] types)

Description copied from interface: MappingFactory

Delete the given mappings.

Specified by:

dropMappings in interface MappingFactory

Parameters:

types - the types to drop

Returns:

true if all mappings were dropped, false otherwise

getAvailableClassMappings

public com.solarmetric.rd.kodo.impl.jdbc.meta.ClassMapping[] getAvailableClassMappings()

Description copied from interface: MappingFactory

Return a list of all available class mappings, ordered from most to least general.

Specified by:

getAvailableClassMappings in interface MappingFactory

getAvailableFieldMappings

public com.solarmetric.rd.kodo.impl.jdbc.meta.FieldMapping[] getAvailableFieldMappings()

Description copied from interface: MappingFactory

Return a list of all available field mappings, ordered from least to most general. When creating a default mapping for a new field, we call the Mapping.map() method on a new instance of each returned mapping util one returns true, or until the list is exhausted. Implementations are free to use or add to the standard mappings list available from FieldMapping.getDefaults().

Specified by:

getAvailableFieldMappings in interface MappingFactory

getAvailableVersionIndicators

public com.solarmetric.rd.kodo.impl.jdbc.meta.VersionIndicator[] getAvailableVersionIndicators()

Description copied from interface: MappingFactory

Return a list of all available version indicators, ordered from most to least general.

Specified by:

getAvailableVersionIndicators in interface MappingFactory

getAvailableClassIndicators

public com.solarmetric.rd.kodo.impl.jdbc.meta.ClassIndicator[] getAvailableClassIndicators()

Description copied from interface: MappingFactory

Return a list of all available class indicators, ordered from most to least general.

Specified by:

getAvailableClassIndicators in interface MappingFactory
