GenericListTypeHandler (reflection-form-builder 1.0-beta2 API)

java.lang.Object
- de.richtercloud.reflection.form.builder.typehandler.GenericListTypeHandler<R,C>

Type Parameters:

R - the reflection form builder to use

C - the component to produce

All Implemented Interfaces:

ComponentHandler<C>, TypeHandler<List<Object>,FieldUpdateEvent<List<Object>>,R,C>
```
public abstract class GenericListTypeHandler<R extends ReflectionFormBuilder,C extends Component>
extends Object
implements TypeHandler<List<Object>,FieldUpdateEvent<List<Object>>,R,C>
```
A TypeHandler which allows to check for an exact type match (which is handled immediately (and the result returned)) and retrieve the type of the List.Furthermore check different class annotations for the base type and the generic list type.

Checks typeClassAnnotationHandlerMapping and then typeHandlerMapping for exact matches.If there're no results, checks typeClassAnnotationHandlerMapping and genericsTypeClassAnnotationHandlerMapping.

Specified by:: handle in interface TypeHandler<List<Object>,FieldUpdateEvent<List<Object>>,R extends ReflectionFormBuilder,C extends Component>
Parameters:: type - the type to handle; fieldValue - the current field value; fieldName - the field name; declaringClass - the class declaring standing on top of the hiearchy using the type; updateListener - the update listener to use; reflectionFormBuilder - the reflection form builder to use
Returns:: the generated component/component handler pair
Throws:: FieldHandlingException - wraps all exceptions occuring during read or write access to fields; ResetException - if an exception during resetting the field occurs
