Class MetadataFactory

java.lang.Object

org.eclipse.persistence.internal.jpa.metadata.accessors.objects.MetadataFactory

Direct Known Subclasses:

MetadataAsmFactory

public abstract class MetadataFactory
extends Object

INTERNAL: A metadata factory is used to extract class information. It is used when processing the metadata model. By default, metadata processing uses an ASM factory, however tools that require a different form of processing, like the APT processor which uses mirrors, can build their own factory by sub-classing this one and supply it at processing time.

Since:

EclipseLink 1.2

addMetadataClass

public void addMetadataClass(MetadataClass metadataClass)

INTERNAL:

addMetadataClass

public void addMetadataClass(String name,
                             MetadataClass metadataClass)

INTERNAL:

getLoader

public ClassLoader getLoader()

INTERNAL:

getLogger

public MetadataLogger getLogger()

INTERNAL:

getMetadataClasses

protected Map<String,MetadataClass> getMetadataClasses()

INTERNAL:

metadataClassExists

protected boolean metadataClassExists(String className)

INTERNAL:

getMetadataClass

public abstract MetadataClass getMetadataClass(String className)

Return the class metadata for the class name.

getMetadataClass

public abstract MetadataClass getMetadataClass(String className,
                                               boolean isLazy)

Return the class metadata for the class name.

setLoader

public void setLoader(ClassLoader loader)

INTERNAL:

setLogger

public void setLogger(MetadataLogger logger)

INTERNAL:

resolveGenericTypes

public abstract void resolveGenericTypes(MetadataClass child,
                                         List<String> genericTypes,
                                         MetadataClass parent,
                                         MetadataDescriptor descriptor)

INTERNAL: This method resolves generic types based on the ASM class metadata. Unless every other factory (e.g. APT mirror factory) respects the generic format as built from ASM this method will not work since it is very tied to it.
