Class AbstractMapperImpl

java.lang.Object
  org.apache.jackrabbit.ocm.mapper.impl.AbstractMapperImpl

All Implemented Interfaces:

Mapper

Direct Known Subclasses:

AnnotationMapperImpl, DigesterMapperImpl

public abstract class AbstractMapperImpl
extends Object
implements Mapper

Abstract class for Mapper

Author:

Lombart Christophe , : Boni Gopalan TODO : Add more reference tests. For exemple, the mapper has to check if the class used for the elements of a collectiondescriptor exists. For performance reasone, we can defined some optional validations.

Method Detail

buildMapper

public void buildMapper()

solveReferences

protected List solveReferences(List errors)

This method check class descriptor references (ancestor & implemented interfaces) : For each classdescriptor found, this method will check if the ancestor class and the implemented interfaces are also persistent or not.

Parameters:

errors -

Returns:

validateDescriptors

protected List validateDescriptors(List errors,
                                   Collection classDescriptors)

Validate all class descriptors. This method validates the toplevel ancestors and after the descendants. Otherwise, we can have invalid settings in the class descriptors

Parameters:

errors - all errors found during the validation process

classDescriptors - the ancestor classdescriptors

Returns:

getErrorMessage

protected String getErrorMessage(List errors)

getClassDescriptorByClass

public ClassDescriptor getClassDescriptorByClass(Class clazz)

Description copied from interface: Mapper

Get the mapping defition to be used for a specific java bean

Specified by:

getClassDescriptorByClass in interface Mapper

Parameters:

clazz - The java bean class

Returns:

The mapping class found for the desired java bean class

See Also:

Mapper.getClassDescriptorByClass(java.lang.Class)

getClassDescriptorByNodeType

public ClassDescriptor getClassDescriptorByNodeType(String jcrNodeType)

Description copied from interface: Mapper

Get the mapping defition to be used for a specific JCR node type

Specified by:

getClassDescriptorByNodeType in interface Mapper

Parameters:

jcrNodeType - the jcr node type

Returns:

The mapping class found for the desired java bean class

See Also:

Mapper.getClassDescriptorByNodeType(String)
