Constructor Detail

AbstractDynamicPersistentMethod

public AbstractDynamicPersistentMethod(Pattern pattern,
                                       org.hibernate.SessionFactory sessionFactory,
                                       ClassLoader classLoader)

Method Detail

getHibernateTemplate

protected HibernateTemplate getHibernateTemplate()

invoke

public Object invoke(Object target,
                     String methodName,
                     Object[] arguments)

Description copied from interface: DynamicMethodInvocation

Invokes the actual method. The target object and arguments are supplied.

Specified by:

invoke in interface DynamicMethodInvocation

Specified by:

invoke in class AbstractDynamicMethodInvocation

Parameters:

target - the target on which the method is invoked.

arguments - the arguments passed in the method call @return the return value of the dynamic method invocation.

doInvokeInternal

protected abstract Object doInvokeInternal(Object target,
                                           Object[] arguments)

setObjectToReadOnly

protected void setObjectToReadOnly(Object target)

This method will set the target object to read-only if it is contained with the Hibernate session, Preventing Hibernate dirty-checking from persisting the instance

Parameters:

target - The target object

setObjectToReadWrite

protected void setObjectToReadWrite(Object target)

setupErrorsProperty

protected Errors setupErrorsProperty(Object target)

Initializes the Errors property on target. The target will be assigned a new Errors property. If the target contains any binding errors, those binding errors will be copied in to the new Errors property. Note that the binding errors will no longer be flagged as binding errors

Parameters:

target - object to initialize

Returns:

the new Errors object
