Method Summary

abstract void	doLoad(Widget frmModel, org.apache.commons.jxpath.JXPathContext jxpc) Performs the actual load binding regardless of the configured value of the "direction" attribute.
abstract void	doSave(Widget frmModel, org.apache.commons.jxpath.JXPathContext jxpc) Performs the actual save binding regardless of the configured value of the "direction" attribute.
void	enableLogging(Logger logger) Receives the Avalon logger to use.
Binding	getClass(String id) Gets a binding class.
String	getId() Returns binding definition id.
protected Logger	getLogger()
protected Widget	getWidget(Widget widget, String id)
void	loadFormFromModel(Widget frmModel, org.apache.commons.jxpath.JXPathContext jxpc) Redefines the Binding action as working on a JXPathContext Type rather then on generic objects.
void	loadFormFromModel(Widget frmModel, Object objModel) Hooks up with the more generic Binding of any objectModel by wrapping it up in a JXPathContext object and then transfering control over to the new overloaded version of this method.
void	saveFormToModel(Widget frmModel, org.apache.commons.jxpath.JXPathContext jxpc) Redefines the Binding action as working on a JXPathContext Type rather then on generic objects.
void	saveFormToModel(Widget frmModel, Object objModel) Hooks up with the more generic Binding of any objectModel by wrapping it up in a JXPathContext object and then transfering control over to the new overloaded version of this method.
void	setParent(Binding binding) Sets parent binding.

Method Detail

setParent

public void setParent(Binding binding)

Sets parent binding.

Specified by:

setParent in interface Binding

Parameters:

binding - Parent of this binding.

getId

public String getId()

Returns binding definition id.

Specified by:

getId in interface Binding

getClass

public Binding getClass(String id)

Description copied from interface: Binding

Gets a binding class.

Specified by:

getClass in interface Binding

Parameters:

id - Id of binding class to get.

getWidget

protected Widget getWidget(Widget widget,
                           String id)

doLoad

public abstract void doLoad(Widget frmModel,
                            org.apache.commons.jxpath.JXPathContext jxpc)
                     throws BindingException

Performs the actual load binding regardless of the configured value of the "direction" attribute. Abstract method that subclasses need to implement for specific activity.

Throws:

BindingException

loadFormFromModel

public final void loadFormFromModel(Widget frmModel,
                                    org.apache.commons.jxpath.JXPathContext jxpc)
                             throws BindingException

Redefines the Binding action as working on a JXPathContext Type rather then on generic objects. Executes the actual loading via doLoad(Widget, JXPathContext) depending on the configured value of the "direction" attribute.

Throws:

BindingException

loadFormFromModel

public final void loadFormFromModel(Widget frmModel,
                                    Object objModel)
                             throws BindingException

Hooks up with the more generic Binding of any objectModel by wrapping it up in a JXPathContext object and then transfering control over to the new overloaded version of this method.

Specified by:

loadFormFromModel in interface Binding

Throws:

BindingException

doSave

public abstract void doSave(Widget frmModel,
                            org.apache.commons.jxpath.JXPathContext jxpc)
                     throws BindingException

Performs the actual save binding regardless of the configured value of the "direction" attribute. Abstract method that subclasses need to implement for specific activity.

Throws:

BindingException

                                  org.apache.commons.jxpath.JXPathContext jxpc)
                           throws BindingException

Redefines the Binding action as working on a JXPathContext Type rather then on generic objects. Executes the actual saving via doSave(Widget, JXPathContext) depending on the configured value of the "direction" attribute.

Throws:

BindingException

saveFormToModel

public void saveFormToModel(Widget frmModel,
                            Object objModel)
                     throws BindingException

Hooks up with the more generic Binding of any objectModel by wrapping it up in a JXPathContext object and then transfering control over to the new overloaded version of this method.

Specified by:

saveFormToModel in interface Binding

Throws:

BindingException

enableLogging

public void enableLogging(Logger logger)

Receives the Avalon logger to use. Subclasses should always start with super.enableLogging(logger) in possible overriding versions.

Specified by:

enableLogging in interface LogEnabled

getLogger

protected Logger getLogger()
