Constructor Detail

AnnotationPersistenceMetaDataParser

public AnnotationPersistenceMetaDataParser(OpenJPAConfiguration conf)
Constructor; supply configuration.

Method Detail

getConfiguration

public OpenJPAConfiguration getConfiguration()
Configuration supplied on construction.


getLog

public Log getLog()
Metadata log.


getRepository

public MetaDataRepository getRepository()
Returns the repository for this parser. If none has been set, create a new repository and sets it.


setRepository

public void setRepository(MetaDataRepository repos)
Set the metadata repository for this parser.


getEnvClassLoader

public ClassLoader getEnvClassLoader()
Return the environmental class loader to pass on to parsed metadata instances.


setEnvClassLoader

public void setEnvClassLoader(ClassLoader loader)
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 annotation partial mapping information can be used even when mappings are stored in another location.


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 annotation partial mapping information can be used even when mappings are stored in another location.


getMode

public int getMode()
The parse mode.


setMode

public void setMode(int mode,
                    boolean on)
The parse mode.


setMode

public void setMode(int mode)
The parse mode.


isMetaDataMode

protected boolean isMetaDataMode()
Convenience method for interpreting getMode().


isQueryMode

protected boolean isQueryMode()
Convenience method for interpreting getMode().


isMappingMode

protected boolean isMappingMode()
Convenience method for interpreting getMode().


isMappingOverrideMode

protected boolean isMappingOverrideMode()
Returns true if we're in mapping mode or in metadata mode with mapping overide enabled.


clear

public void clear()
Clear caches.


parse

public void parse(Class cls)
Parse persistence metadata for the given class.


parsePackageMappingAnnotations

protected void parsePackageMappingAnnotations(Package pkg)
Parse package mapping annotations.


handleUnknownPackageAnnotation

protected boolean handleUnknownPackageAnnotation(Package pkg,
                                                 Annotation anno)
Allow subclasses to handle unknown annotations.


parseClassMappingAnnotations

protected void parseClassMappingAnnotations(ClassMetaData meta)
Parse class mapping annotations.


handleUnknownClassAnnotation

protected boolean handleUnknownClassAnnotation(ClassMetaData meta,
                                               Annotation anno)
Allow subclasses to handle unknown annotations.


getSourceFile

protected File getSourceFile()
Determine the source file we're parsing.


parseCallbackMethods

public static Collection<LifecycleCallbacks>[] parseCallbackMethods(Class cls,
                                                                    Collection<LifecycleCallbacks>[] callbacks,
                                                                    boolean sups,
                                                                    boolean listener,

Parse callback methods into the given array, and return that array, creating one if null. Each index into the array is a collection of callback adapters for that numeric event type.

Parameters:
sups - whether to scan superclasses
listener - whether this is a listener or not

parseMemberMappingAnnotations

protected void parseMemberMappingAnnotations(FieldMetaData fmd)

Sets value generation information for the given field.


parseLobMapping

protected void parseLobMapping(FieldMetaData fmd)
Setup the field as a LOB mapping.
