Constructor Detail

CustomJXPathBinding

public CustomJXPathBinding(JXPathBindingBuilderBase.CommonAttributes commonAtts,
                           String widgetId,
                           String xpath,
                           AbstractCustomBinding wrappedBinding)
Constructs CustomJXPathBinding

Parameters:
commonAtts - common configuration attributes JXPathBindingBuilderBase.CommonAttributes
widgetId - id of the widget to bind to
xpath - jxpath expression to narrow down the context to before calling the wrapped Binding
wrappedBinding - the actual custom written Binding implementation of Binding
Method Detail

getXPath

public String getXPath()

getId

public String getId()
Description copied from class: JXPathBindingBase
Returns binding definition id.

Specified by:
getId in interface Binding
Overrides:
getId in class JXPathBindingBase

getWrappedBinding

public AbstractCustomBinding getWrappedBinding()

doLoad

public void doLoad(Widget frmModel,
                   org.apache.commons.jxpath.JXPathContext jxpc)
            throws BindingException
Delegates the actual loading operation to the provided Custom Binding Class after narrowing down on the selected widget (@id) and context (@path)

Specified by:
doLoad in class JXPathBindingBase
Parameters:
frmModel - the narrowed widget-scope from the parent binding
jxpc - the narrowed jxpath context from the parent binding
Throws:
BindingException - when the wrapped CustomBinding fails

doSave

public void doSave(Widget frmModel,
                   org.apache.commons.jxpath.JXPathContext jxpc)
            throws BindingException
Delegates the actual saving operation to the provided Custom Binding Class after narrowing down on the selected widget (@id) and context (@path)

Specified by:
doSave in class JXPathBindingBase
Parameters:
frmModel - the narrowed widget-scope from the parent binding
jxpc - the narrowed jxpath context from the parent binding
Throws:
BindingException - when the wrapped CustomBinding fails
