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

protected java.lang.Object handleValidationError(java.lang.Object target, 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.

static boolean isAutoValidationDisabled(java.lang.Object obj)

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

Associates the Errors object on the instance

Method Detail

doInvokeInternal

@SuppressWarnings("rawtypes")
@Override
protected java.lang.Object doInvokeInternal(java.lang.Object target, Object[] arguments)

handleValidationError

protected java.lang.Object handleValidationError(java.lang.Object target, 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

isAutoValidationDisabled

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

performInsert

protected 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

performSave

protected 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

setErrorsOnInstance

protected void setErrorsOnInstance(java.lang.Object target, Errors errors)
Associates the Errors object on the instance
Parameters:
target - The target instance
errors - The Errors object
