                           throws ClassNotFoundException,
                                  javax.jcr.RepositoryException

Description copied from interface: Node2BeanTransformer

Resolves the class to use for the current node.

Specified by:

resolveType in interface Node2BeanTransformer

Throws:

ClassNotFoundException

javax.jcr.RepositoryException

getChildren

public javax.jcr.NodeIterator getChildren(javax.jcr.Node node)
                                   throws javax.jcr.RepositoryException

Description copied from interface: Node2BeanTransformer

Returns the children of the node to be transformed. Those are normally the direct children but might differ.

Specified by:

getChildren in interface Node2BeanTransformer

Throws:

javax.jcr.RepositoryException

newBeanInstance

public Object newBeanInstance(TransformationState state,
                     Map<String,Object> values,
                     ComponentProvider componentProvider)
                       throws Node2BeanException

Description copied from interface: Node2BeanTransformer

Instantiates the bean.

Specified by:

newBeanInstance in interface Node2BeanTransformer

Throws:

Node2BeanException

initBean

public void initBean(TransformationState state,
            Map values)
              throws Node2BeanException

Description copied from interface: Node2BeanTransformer

Called after all properties are set.

Specified by:

initBean in interface Node2BeanTransformer

Throws:

Node2BeanException

convertPropertyValue

public Object convertPropertyValue(Class<?> propertyType,
                          Object value)
                            throws Node2BeanException

                                                InvocationTargetException

Creates collection from map. Collection type depends on passed class parameter. If passed class parameter is interface, then default implementation will be used for creating collection.
By default

• LinkedList is used for creating List and Queue collections.
• HashSet is used for creating Set collection.

If passed class parameter is an implementation of any collection type, then this method will create this implementation and returns it.

Parameters:

map - a map which values will be converted to a collection

clazz - collection type

Returns:

Collection of elements or null.

Throws:

SecurityException

NoSuchMethodException

IllegalArgumentException

InstantiationException

IllegalAccessException

InvocationTargetException
