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,

                       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

Description copied from interface: Node2BeanTransformer

                                                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
