Method Detail

findBaseClassViaMappings

public <T> CFMappingDef<? super T> findBaseClassViaMappings(CFMappingDef<T> cfMapDef)

Examine class hierarchy using CFMappingDef objects to discover the given class' "base inheritance" class. A base inheritance class is determined by CFMappingDef.isBaseEntity()

Type Parameters:

T -

Parameters:

cfMapDef -

Returns:

returns the base in the ColumnFamily mapping hierarchy

getCfMapDef

public <T> CFMappingDef<T> getCfMapDef(Class<T> clazz,
                              boolean throwException)

Retrieve class mapping meta-data by Class object.

Type Parameters:

T -

Parameters:

clazz -

throwException -

Returns:

CFMappingDef if found, exception if throwException = true, and null otherwise

getCfMapDef

public <T> CFMappingDef<T> getCfMapDef(String colFamName,
                              boolean throwException)

Retrieve class mapping meta-data by ColumnFamily name.

Type Parameters:

T -

Parameters:

colFamName -

throwException -

Returns:

CFMappingDef if found, exception if throwException = true, and null otherwise

initializeCacheForClass

public <T> CFMappingDef<T> initializeCacheForClass(Class<T> clazz)

For each class that should be managed, this method must be called to parse its annotations and derive its meta-data.

Type Parameters:

T -

Parameters:

clazz -

Returns:

CFMapping describing the initialized class.

getFieldPropertyDescriptorMap

public Map<String,PropertyDescriptor> getFieldPropertyDescriptorMap(Class<?> clazz)
                                                             throws IntrospectionException

Throws:

IntrospectionException

findAnnotatedMethod

public Method findAnnotatedMethod(Class<?> clazz,
                         Class<? extends Annotation> anno)

Find method annotated with the given annotation.

Parameters:

clazz -

anno -

Returns:

returns Method if found, null otherwise
