Constructor Detail

XMLMappingLoader

public XMLMappingLoader(java.lang.ClassLoader loader)

Creates a new XMLMappingLoader

Method Detail

getBindingType

public BindingType getBindingType()

resolveRelations

protected void resolveRelations(ClassDescriptor clsDesc)

Overrides:

resolveRelations in class AbstractMappingLoader

createDescriptor

protected ClassDescriptor createDescriptor(ClassMapping clsMap)
                                    throws MappingException

Description copied from class: AbstractMappingLoader

Creates a new descriptor. The class mapping information is used to create a new stock ClassDescriptor. Implementations may extend this class to create a more suitable descriptor.

Overrides:

createDescriptor in class AbstractMappingLoader

Parameters:

clsMap - The class mapping information.

Throws:

MappingException - An exception indicating why mapping for the class cannot be created.

createFieldDesc

protected FieldDescriptor createFieldDesc(java.lang.Class javaClass,
                                          FieldMapping fieldMap)
                                   throws MappingException

Description copied from class: AbstractMappingLoader

Creates a single field descriptor. The field mapping is used to create a new stock FieldDescriptor. Implementations may extend this class to create a more suitable descriptor.

Overrides:

createFieldDesc in class AbstractMappingLoader

Parameters:

javaClass - The class to which the field belongs.

fieldMap - The field mapping information.

Returns:

The field descriptor.

Throws:

MappingException - The field or its accessor methods are not found, not accessible, not of the specified type, etc.

setLoadPackageMappings

public void setLoadPackageMappings(boolean loadPackageMappings)

Sets whether or not to look for and load package specific mapping files (".castor.xml" files).

Parameters:

loadPackageMappings - a boolean that enables or disables the loading of package specific mapping files

getTypeInfo

protected TypeInfo getTypeInfo(java.lang.Class fieldType,
                               CollectionHandler colHandler,
                               FieldMapping fieldMap)
                        throws MappingException

Overrides:

getTypeInfo in class AbstractMappingLoader

Throws:

MappingException
