store

public boolean store(ClassMetaData[] metas,
                     QueryMetaData[] queries,

                     int mode,
                     Map output)

Description copied from interface: MetaDataFactory

Store the given metadata.

Specified by:

store in interface MetaDataFactory

Overrides:

store in class AbstractMetaDataFactory

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

                    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 AbstractMetaDataFactory

Returns:

false if any metadata could not be dropped

isMappingOnlyFactory

protected boolean isMappingOnlyFactory()

Return true if this factory deals only with mapping data, and relies on a separate factory for metadata.

protected void parse(MetaDataParser parser,
                     Collection files)

Parse all given files.

parse

protected void parse(MetaDataParser parser,
