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

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
