Constructor Detail

MetaDataPlusMappingFactory

public MetaDataPlusMappingFactory(MetaDataFactory meta,
                                  MetaDataFactory map)

Constructor; supply delegates.

Method Detail

getMappingDelegate

public MetaDataFactory getMappingDelegate()

Mapping factory delegate.

getInnermostMappingDelegate

public MetaDataFactory getInnermostMappingDelegate()

Innermost mapping delegate.

setRepository

public void setRepository(MetaDataRepository repos)

Description copied from interface: MetaDataFactory

Set the repository to load metadata into. This method will be called before use.

Specified by:

setRepository in interface MetaDataFactory

Overrides:

setRepository in class DelegatingMetaDataFactory

setStoreDirectory

public void setStoreDirectory(File dir)

Description copied from interface: MetaDataFactory

Base directory for storing metadata. May not be called.

Specified by:

setStoreDirectory in interface MetaDataFactory

Overrides:

setStoreDirectory in class DelegatingMetaDataFactory

setStoreMode

public void setStoreMode(int store)

Description copied from interface: MetaDataFactory

Storage mode. May not be called.

Specified by:

setStoreMode in interface MetaDataFactory

Overrides:

setStoreMode in class DelegatingMetaDataFactory

setStrict

public void setStrict(boolean strict)

Description copied from interface: MetaDataFactory

If true, I/O's must exactly obey the mode directives given, and may not load additional information.

Specified by:

setStrict in interface MetaDataFactory

Overrides:

setStrict in class DelegatingMetaDataFactory

load

public void load(Class cls,
                 int mode,
                 ClassLoader envLoader)

Description copied from interface: MetaDataFactory

Load metadata for the given class in the given mode(s). If loading in MetaDataModes.MODE_QUERY, the class may be null. Loaded metadata should be added directly to the repository. It should have its source mode set appropriately via ClassMetaData.setSourceMode(int).

Specified by:

load in interface MetaDataFactory

Overrides:

load in class DelegatingMetaDataFactory

mode - the mode to load metadata in: if mapping information is stored together with metadata, then you can load mapping data even if this mode only includes MODE_META, so long as the strict property hasn't been set

store

public boolean store(ClassMetaData[] metas,
                     QueryMetaData[] queries,
                     SequenceMetaData[] seqs,
                     int mode,
                     Map output)

Description copied from interface: MetaDataFactory

Store the given metadata.

Specified by:

store in interface MetaDataFactory

Overrides:

store in class DelegatingMetaDataFactory

mode - hint about what aspects of the metadata have changed

output - if non-null, rather than storing metadata directly, add entries mapping each output destination such as a File to the planned output for that destination in string form

Returns:

false if this factory is unable to store metadata

drop

public boolean drop(Class[] cls,
                    int mode,
                    ClassLoader envLoader)

Description copied from interface: MetaDataFactory

Drop the metadata for the given classes in the given mode(s).

Specified by:

drop in interface MetaDataFactory

Overrides:

drop in class DelegatingMetaDataFactory

Returns:

false if any metadata could not be dropped

getPersistentTypeNames

public Set getPersistentTypeNames(boolean classpath,
                                  ClassLoader envLoader)

Description copied from interface: MetaDataFactory

Return all persistent class names, using the metadata locations supplied in configuration, optionally scanning the classpath. Return null if no types are supplied and this factory is unable to scan the classpath. This method should not be used directly by outside code; use MetaDataRepository.getPersistentTypeNames(boolean, java.lang.ClassLoader) instead.

Specified by:

getPersistentTypeNames in interface MetaDataFactory

Overrides:

getPersistentTypeNames in class DelegatingMetaDataFactory

See Also:

MetaDataRepository.getPersistentTypeNames(boolean, java.lang.ClassLoader), MetaDataRepository.loadPersistentTypes(boolean, java.lang.ClassLoader)

clear

public void clear()

Description copied from interface: MetaDataFactory

Clear any internal caches.

Specified by:

clear in interface MetaDataFactory

Overrides:

clear in class DelegatingMetaDataFactory

addClassExtensionKeys

public void addClassExtensionKeys(Collection exts)

Description copied from interface: MetaDataFactory

Add any extension keys used by this instance to the given set.

Specified by:

addClassExtensionKeys in interface MetaDataFactory

Overrides:

addClassExtensionKeys in class DelegatingMetaDataFactory

addFieldExtensionKeys

public void addFieldExtensionKeys(Collection exts)

Description copied from interface: MetaDataFactory

Add any extension keys used by this instance to the given set.

Specified by:

addFieldExtensionKeys in interface MetaDataFactory

Overrides:

addFieldExtensionKeys in class DelegatingMetaDataFactory
