Method Detail

getFetchConfiguration

public FetchConfiguration getFetchConfiguration()

Description copied from interface: KodoExtent

Return the (mutable) fetch configuration for this extent.

Specified by:

getFetchConfiguration in interface KodoExtent

getIgnoreCache

public boolean getIgnoreCache()

Description copied from interface: KodoExtent

Whether this extent will ignore the persistence manager cache.

Specified by:

getIgnoreCache in interface KodoExtent

setIgnoreCache

public void setIgnoreCache(boolean)

Description copied from interface: KodoExtent

Whether this extent will ignore the persistence manager cache.

Specified by:

setIgnoreCache in interface KodoExtent

list

public List list()

Description copied from interface: KodoExtent

Returns a list of all objects represented by this extent. This method creates a List by traversing the entire iterator returned by a call to Extent.iterator(). This means that Collection.size() will work correctly, but if the extent represents a large data set, this method may be quite slow and may consume quite a bit of memory.

Specified by:

list in interface KodoExtent

iterator

public Iterator iterator()

Specified by:

iterator in interface Extent

getPersistenceManager

public PersistenceManager getPersistenceManager()

Specified by:

getPersistenceManager in interface Extent

getCandidateClass

public Class getCandidateClass()

Specified by:

getCandidateClass in interface Extent

hasSubclasses

public boolean hasSubclasses()

Specified by:

hasSubclasses in interface Extent

closeAll

public void closeAll()

Specified by:

closeAll in interface Extent

close

public void close(Iterator)

Specified by:

close in interface Extent

getResultObjectProvider

protected abstract ResultObjectProvider getResultObjectProvider(ClassMetaData)
