Constructor Summary | |
---|---|
PersistentDescriptor()
Creates a PersistentDescriptor. |
Method Summary | |
---|---|
void |
addDeclaredProperty(Property property)
Registers a property. |
void |
addSubclassDescriptor(ClassDescriptor subclassDescriptor)
|
Object |
createObject()
Creates a new instance of a class described by this object. |
Property |
getDeclaredProperty(String propertyName)
Returns a Java Bean property descriptor matching property name or null if no such property is found. |
ObjEntity |
getEntity()
Returns an ObjEntity associated with this descriptor. |
Iterator |
getIdProperties()
Returns an iterator over the properties mapped to id columns. |
Class |
getObjectClass()
Returns a class mapped by this descriptor. |
Iterator |
getProperties()
Deprecated. since 3.0. Use visitProperties(PropertyVisitor) method
instead. |
Property |
getProperty(String propertyName)
Recursively looks up property descriptor in this class descriptor and all superclass descriptors. |
ClassDescriptor |
getSubclassDescriptor(Class objectClass)
Returns the most "specialized" descriptor for a given class. |
ClassDescriptor |
getSuperclassDescriptor()
Returns a descriptor of the mapped superclass or null if the descriptor's entity sits at the top of inheritance hierarchy. |
void |
injectValueHolders(Object object)
Invokes 'prepareForAccess' of a super descriptor and then invokes 'prepareForAccess' of each declared property. |
boolean |
isFault(Object object)
Returns true if an object is not fully resolved. |
void |
removeDeclaredProperty(String propertyName)
Removes declared property. |
void |
setEntity(ObjEntity entity)
|
void |
setPersistenceStateAccessor(Accessor persistenceStateAccessor)
|
void |
setSuperclassDescriptor(ClassDescriptor superclassDescriptor)
|
void |
shallowMerge(Object from,
Object to)
Copies object properties from one object to another. |
boolean |
visitAllProperties(PropertyVisitor visitor)
Passes the visitor to the properties "visit" method for all properties declared in this descriptor, its super and subdescriptors, terminating properties walkthrough in case one of the properties returns false. |
boolean |
visitDeclaredProperties(PropertyVisitor visitor)
Passes the visitor to the properties "visit" method for all properties declared in this descriptor, terminating properties walkthrough in case one of the properties returns false. |
boolean |
visitProperties(PropertyVisitor visitor)
Passes the visitor to all properties "visit" method, terminating properties walkthrough in case one of the properties returns false. |
