Class FileMappingFactory

java.lang.Object
  |
  +--kodo.jdbc.meta.FileMappingFactory

All Implemented Interfaces:

Configurable, MappingFactory

public class FileMappingFactory

extends Object

implements MappingFactory, Configurable

Factory that uses multiple XML mapping files to construct the system mappings. By default, the placement of the mapping files mirrors the placement of the JDO metadata.

Constructor Summary

FileMappingFactory()

Method Summary

boolean	dropMappings(ClassMetaData[] types) Delete the given mappings.
void	endConfiguration() Invoked upon completion of bean property configuration for this object.
String	getFileName() The name of the file to use in single-file mode.
boolean	isSingleFile() Whether to use a single top-level mapping file.
boolean	isSingleOperation() Return true if this factory reads and writes all system mappings at once.
void	readMapping(ClassMetaData type, MappingInfoRepository repos) Read the object-relational mapping for the given persistent type and add it to the given repository.
boolean	revertMappings(ClassMetaData[] types) Revert the mappings to their last saved state, or return false if any cannot be reverted.
void	setConfiguration(Configuration conf) Invoked prior to setting bean properties.
void	setFileName(String fileName) The name of the file to use in single-file mode.
void	setSingleFile(boolean singleFile) Whether to use a single top-level mapping file.
void	startConfiguration() Invoked before bean property configuration is begun on this object.
void	storeMappings(MappingInfoRepository mappings, JDOMetaDataRepository repos) Store any changes made to the given mappings, including their field mappings.

Constructor Detail

FileMappingFactory

public FileMappingFactory()

Method Detail

isSingleFile

public boolean isSingleFile()

Whether to use a single top-level mapping file. If false then mapping files mirror the placement of the corresponding JDO metadata files.

setSingleFile

public void setSingleFile(boolean singleFile)

Whether to use a single top-level mapping file. If false then mapping files mirror the placement of the corresponding JDO metadata files.

getFileName

public String getFileName()

The name of the file to use in single-file mode. Defaults to package.mapping.

setFileName

public void setFileName(String fileName)

The name of the file to use in single-file mode. Defaults to package.mapping.

setConfiguration

public void setConfiguration(Configuration conf)

Description copied from interface: Configurable

Invoked prior to setting bean properties.

Specified by:

setConfiguration in interface Configurable

startConfiguration

public void startConfiguration()

Description copied from interface: Configurable

Invoked before bean property configuration is begun on this object.

Specified by:

startConfiguration in interface Configurable

endConfiguration

public void endConfiguration()

Description copied from interface: Configurable

Invoked upon completion of bean property configuration for this object.

Specified by:

endConfiguration in interface Configurable

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(kodo.meta.ClassMetaData, kodo.jdbc.meta.MappingInfoRepository) and MappingFactory.revertMappings(kodo.meta.ClassMetaData[]) calls that pass in a null meta data argument.

Specified by:

isSingleOperation in interface MappingFactory

readMapping

public void readMapping(ClassMetaData type,
                        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

Following copied from interface: kodo.jdbc.meta.MappingFactory

Parameters:

type - the type to read mapping information for

repos - add the mapping information to this repository

storeMappings

public void storeMappings(MappingInfoRepository mappings,
                          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

Following copied from interface: kodo.jdbc.meta.MappingFactory

Parameters:

mappings - the changed mappings

repos - can be used to access class metadata if needed

dropMappings

public boolean dropMappings(ClassMetaData[] types)

Description copied from interface: MappingFactory

Delete the given mappings.

Specified by:

dropMappings in interface MappingFactory

Following copied from interface: kodo.jdbc.meta.MappingFactory

Parameters:

types - the types to drop

Returns:

true if all mappings were dropped, false otherwise

revertMappings

public boolean revertMappings(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

Following copied from interface: kodo.jdbc.meta.MappingFactory

Parameters:

types - the types to revert

Returns:

true if all mappings were reverted, false otherwise
