BLCFieldUtils

public BLCFieldUtils(boolean includeUnqualifiedPolymorphicEntities,
 boolean useCache,
 EntityConfiguration entityConfiguration,
 DynamicDaoHelper helper)

Initialize the utility with required resources

Parameters:

includeUnqualifiedPolymorphicEntities - include polymorphic variations that were excluded with AdminPresentationClass.excludeFromPolymorphism()

useCache - use the polymorphic type list cache in DynamicDaoHelperImpl

entityConfiguration - contains any explicitly defined entity types for the system

helper - helper class for retrieving polymorphic types for a ceiling domain class

Method Details

getSingleField

public static Field getSingleField(Class<?> clazz,
 String fieldName)
                            throws IllegalStateException

Retrieve the field for the class. This method will also look in superclasses.

Parameters:

clazz -

fieldName -

Returns:

Throws:

IllegalStateException

getField

public Field getField(Class<?> clazz,
 String fieldName)
               throws IllegalStateException

Retrieve the field for the class. This method will look in the entire inheritance hierarchy for the class (if applicable) and will also honor multiple field traversals in the fieldName using a period delimeter.

Parameters:

clazz -

fieldName -

Returns:

Throws:

IllegalStateException

getClassForField

protected Class<?> getClassForField(DynamicDaoHelper helper,
 String token,
 Field field,
 Class<?>[] entities)
