```
    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
