Method Detail

isAutoValidationDisabled

public static boolean isAutoValidationDisabled(java.lang.Object obj)

clearDisabledValidations

public static void clearDisabledValidations(java.lang.Object obj)

clearDisabledValidations

public static void clearDisabledValidations()

doInvokeInternal

protected java.lang.Object doInvokeInternal(java.lang.Object target,
                                            java.lang.Object[] arguments)

Specified by:

doInvokeInternal in class AbstractDynamicPersistentMethod

handleValidationError

protected java.lang.Object handleValidationError(java.lang.Object target,
                                                 org.springframework.validation.Errors errors)

Sets the flush mode to manual. which ensures that the database changes are not persisted to the database if a validation error occurs. If save() is called again and validation passes the code will check if there is a manual flush mode and flush manually if necessary

Parameters:

target - The target object that failed validation

errors - The Errors instance

Returns:

This method will return null signaling a validation failure

setErrorsOnInstance

protected void setErrorsOnInstance(java.lang.Object target,
                                   org.springframework.validation.Errors errors)

Associates the Errors object on the instance

Parameters:

target - The target instance

errors - The Errors object

performSave

protected abstract java.lang.Object performSave(java.lang.Object target,
                                                boolean shouldFlush)

Subclasses should override and perform a save operation, flushing the session if the second argument is true

Parameters:

target - The target object to save

shouldFlush - Whether to flush

Returns:

The target object

performInsert

protected abstract java.lang.Object performInsert(java.lang.Object target,
                                                  boolean shouldFlush)

Subclasses should override and perform an insert operation, flushing the session if the second argument is true

Parameters:

target - The target object to save

shouldFlush - Whether to flush

Returns:

The target object
