public XMLPersistenceMetaDataParser(OpenJPAConfiguration conf)

Constructor; supply configuration.

Method Detail

getConfiguration

public OpenJPAConfiguration getConfiguration()

Configuration supplied on construction.

getAnnotationParser

public AnnotationPersistenceMetaDataParser getAnnotationParser()

The annotation parser. When class is discovered in an XML file, we first parse any annotations present, then override with the XML.

setAnnotationParser

public void setAnnotationParser(AnnotationPersistenceMetaDataParser parser)

The annotation parser. When class is discovered in an XML file, we first parse any annotations present, then override with the XML.

getRepository

public MetaDataRepository getRepository()

Returns the repository for this parser. If none has been set, creates a new repository and sets it.

Specified by:

getRepository in interface AbstractCFMetaDataFactory.Parser

setRepository

public void setRepository(MetaDataRepository repos)

Set the metadata repository for this parser.

getEnvClassLoader

public ClassLoader getEnvClassLoader()

Set the environmental class loader to pass on to parsed metadata instances.

getMappingOverride

public boolean getMappingOverride()

Whether to allow later parses of mapping information to override earlier information for the same class. Defaults to false. Useful when a tool is mapping a class, so that .jdo file partial mapping information can be used even when mappings are stored in .orm files or other locations.

setMappingOverride

public void setMappingOverride(boolean override)

Whether to allow later parses of mapping information to override earlier information for the same class. Defaults to false. Useful when a tool is mapping a class, so that .jdo file partial mapping information can be used even when mappings are stored in .orm files or other locations.

public int getMode()

The parse mode according to the expected document type. The mode constants act as bit flags, and therefore can be combined.
