Constructor Detail

NodePropertyHelper

public NodePropertyHelper(org.alfresco.service.cmr.dictionary.DictionaryService dictionaryService,
                          QNameDAO qnameDAO,
                          LocaleDAO localeDAO,
                          ContentDataDAO contentDataDAO)

Construct the helper with the appropriate DAOs and services

Method Detail

convertToPersistentProperties

public Map<NodePropertyKey,NodePropertyValue> convertToPersistentProperties(Map<org.alfresco.service.namespace.QName,Serializable> in)

makeNodePropertyValue

public NodePropertyValue makeNodePropertyValue(org.alfresco.service.cmr.dictionary.PropertyDefinition propertyDef,
                                               Serializable value)

Helper method to convert the Serializable value into a full, persistable NodePropertyValue.

Where the property definition is null, the value will take on the generic ANY value.

Collections are NOT supported. These must be split up by the calling code before calling this method. Map instances are supported as plain serializable instances.

Parameters:

propertyDef - the property dictionary definition, may be null

value - the value, which will be converted according to the definition - may be null

Returns:

Returns the persistable property value

getPublicProperty

public Serializable getPublicProperty(Map<NodePropertyKey,NodePropertyValue> propertyValues,
                                      org.alfresco.service.namespace.QName propertyQName)

convertToPublicProperties

public Map<org.alfresco.service.namespace.QName,Serializable> convertToPublicProperties(Map<NodePropertyKey,NodePropertyValue> propertyValues)

makeSerializableValue

public Serializable makeSerializableValue(org.alfresco.service.cmr.dictionary.PropertyDefinition propertyDef,
                                          NodePropertyValue propertyValue)

Extracts the externally-visible property from the persistable value.

Parameters:

propertyDef - the model property definition - may be null

propertyValue - the persisted property

Returns:

Returns the value of the property in the format dictated by the property definition, or null if the property value is null
