Methods inherited from class java.lang.Object
`clone, finalize, getClass, notify, notifyAll, wait, wait, wait`

Constructor Detail

AbstractBindingResult

protected AbstractBindingResult(String objectName)

Create a new AbstractBindingResult instance.

Parameters:: objectName - the name of the target object
See Also:: DefaultMessageCodesResolver

Method Detail

setMessageCodesResolver

public void setMessageCodesResolver(MessageCodesResolver messageCodesResolver)

Set the strategy to use for resolving errors into message codes. Default is DefaultMessageCodesResolver.

See Also:: DefaultMessageCodesResolver

getMessageCodesResolver

public MessageCodesResolver getMessageCodesResolver()

Return the strategy to use for resolving errors into message codes.

getObjectName

public String getObjectName()

Description copied from interface: Errors

Return the name of the bound root object.

Specified by:: getObjectName in interface Errors

setNestedPath

public void setNestedPath(String nestedPath)

Description copied from interface: Errors

Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.

For example, an address validator could validate the subobject "address" of a customer object.

Specified by:: setNestedPath in interface Errors

Parameters:: nestedPath - nested path within this object, e.g. "address" (defaults to "", null is also acceptable). Can end with a dot: both "address" and "address." are valid.

getNestedPath

public String getNestedPath()

Description copied from interface: Errors

Return the current nested path of this Errors object.

Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.

Specified by:: getNestedPath in interface Errors

pushNestedPath

public void pushNestedPath(String subPath)

Description copied from interface: Errors

Push the given sub path onto the nested path stack.

A Errors.popNestedPath() call will reset the original nested path before the corresponding pushNestedPath(String) call.

Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.

For example: current path "spouse.", pushNestedPath("child") -> result path "spouse.child."; popNestedPath() -> "spouse." again.

Specified by:: pushNestedPath in interface Errors

Parameters:: subPath - the sub path to push onto the nested path stack
See Also:: Errors.popNestedPath()

popNestedPath

public void popNestedPath()
                   throws IllegalArgumentException

Description copied from interface: Errors

Pop the former nested path from the nested path stack.

Specified by:: popNestedPath in interface Errors

Throws:: IllegalArgumentException
See Also:: Errors.pushNestedPath(java.lang.String)

doSetNestedPath

protected void doSetNestedPath(String nestedPath)

Actually set the nested path. Delegated to by setNestedPath and pushNestedPath.

fixedField

protected String fixedField(String field)

Transform the given field into its full path, regarding the nested path of this instance.

Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.

The attributes in the model Map returned by this method are usually included in the ModelAndView for a form view that uses Spring's bind tag, which needs access to the Errors instance. Spring's SimpleFormController will do this for you when rendering its form or success view. When building the ModelAndView yourself, you need to include the attributes from the model Map returned by this method yourself.
