All Known Implementing Classes:

CollectionPropertyHidingTransformer, CommandTransformer, CompositeFilterTransformer, IPSecurityManagerImpl.IPSecurityManagerTransformer, Node2BeanTransformerImpl, VoterSetTransformer

public interface Node2BeanTransformer

Contract for transformation from node to java beans.

Method Summary

Object	convertPropertyValue(Class<?> propertyType, Object value) Transforms the simple basic jcr property value objects to more complex properties.
javax.jcr.NodeIterator	getChildren(javax.jcr.Node node) Returns the children of the node to be transformed.
void	initBean(TransformationState state, Map<String,Object> values) Called after all properties are set.
Object	newBeanInstance(TransformationState state, Map<String,Object> values, ComponentProvider componentProvider) Instantiates the bean.
TransformationState	newState() Create a state object to share the state between the processor and transformer.
TypeDescriptor	resolveType(TypeMapping typeMapping, TransformationState state, ComponentProvider componentProvider) Resolves the class to use for the current node.
void	setProperty(TypeMapping typeMapping, TransformationState state, PropertyTypeDescriptor descriptor, Map<String,Object> values) Set this property on that bean.

Method Detail

newState

TransformationState newState()

Create a state object to share the state between the processor and transformer.

resolveType

TypeDescriptor resolveType(TypeMapping typeMapping,
                           TransformationState state,
                           ComponentProvider componentProvider)
                           throws ClassNotFoundException,
                                  javax.jcr.RepositoryException

Resolves the class to use for the current node.

Throws:

ClassNotFoundException

javax.jcr.RepositoryException

getChildren

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

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

Throws:

javax.jcr.RepositoryException

newBeanInstance

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

Instantiates the bean.

Throws:

Node2BeanException

initBean

void initBean(TransformationState state,
              Map<String,Object> values)
              throws Node2BeanException

Called after all properties are set.

Throws:

Node2BeanException

setProperty

void setProperty(TypeMapping typeMapping,
                 TransformationState state,
                 PropertyTypeDescriptor descriptor,
                 Map<String,Object> values)
                 throws javax.jcr.RepositoryException

Set this property on that bean. Allows excluding of properties.

Throws:

javax.jcr.RepositoryException

convertPropertyValue

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

Transforms the simple basic jcr property value objects to more complex properties.

Throws:

Node2BeanException
