JDOMappingLoader
public JDOMappingLoader(java.lang.ClassLoader loader,
java.io.PrintWriter logWriter)
createDescriptor
protected ClassDescriptor createDescriptor(ClassMapping clsMap)
throws MappingException
- Description copied from class:
MappingLoader
- 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 MappingLoader
- Parameters:
clsMap
- The class mapping information
- Throws:
MappingException
- An exception indicating why mapping for
the class cannot be created
getSqlTypes
protected java.lang.String[] getSqlTypes(FieldMapping fieldMap)
- Parse the sql type attribute to build an
array of types, needed to support whitespace inside
parameterized types (see Bug 1045)
getTypeInfo
protected TypeInfo getTypeInfo(java.lang.Class fieldType,
CollectionHandler colHandler,
FieldMapping fieldMap)
throws MappingException
- Overrides:
getTypeInfo
in class MappingLoader
- Throws:
MappingException
createFieldDesc
protected FieldDescriptor createFieldDesc(java.lang.Class javaClass,
FieldMapping fieldMap)
throws MappingException
- Description copied from class:
MappingLoader
- 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 MappingLoader
- Parameters:
javaClass
- The class to which the field belongsfieldMap
- 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
loadMapping
public void loadMapping(MappingRoot mapping,
java.lang.Object param)
throws MappingException
- Description copied from class:
MappingLoader
- Loads the mapping from the specified mapping object. Calls
MappingLoader.createDescriptor(org.exolab.castor.mapping.xml.ClassMapping)
to create each descriptor and MappingLoader.addDescriptor(org.exolab.castor.mapping.ClassDescriptor)
to store it. Also loads all the included mapping
files.
- Overrides:
loadMapping
in class MappingLoader
- Parameters:
mapping
- The mapping informationparam
- Arbitrary parameter that can be used by subclasses
- Throws:
MappingException
- The mapping file is invalid
