Field Detail

binding_state

protected short binding_state

the current binding state, one of the above

contextNode

protected InstanceNode contextNode

Repeat may set this context node

refNodes

protected org.w3c.dom.NodeList refNodes

The nodelist for multiple node binding

refNode

protected org.w3c.dom.Node refNode

used for containing bindings context node

Constructor Detail

ModelBoundElementImpl

public ModelBoundElementImpl(XFormsElementHandler handler,
                             java.lang.String ns,
                             java.lang.String name)

Method Detail

getBindingState

public short getBindingState()

returns the current binding state

Specified by:

getBindingState in interface ElementWithContext

getBoundNodeset

public org.w3c.dom.NodeList getBoundNodeset()

resetContextNode

public void resetContextNode()

reset my context node

Specified by:

resetContextNode in interface ElementWithContext

getContextFromAncestor

protected void getContextFromAncestor(ElementWithContext refElem)
                               throws XFormsBindingException

this method will get the context node from an possible ancestor element. Used also by ModelBoundElement.

Throws:

XFormsBindingException

getParentBoundElement

protected static ElementWithContext getParentBoundElement(org.w3c.dom.Node start,
                                                          ElementWithContext refElem)

Used also by ModelBoundElement.

createBinding

public org.w3c.dom.NodeList createBinding()
                                   throws XFormsBindingException

Search for my reference nodes this always executes the binding expression!

Throws:

XFormsBindingException

getContextForDescendant

public InstanceNode getContextForDescendant()

Description copied from interface: ElementWithContext

an descendant asks for its context

Specified by:

getContextForDescendant in interface ElementWithContext

destroy

public void destroy()

Description copied from class: XSmilesElementImpl

Destroy this element and its descendants recursively. NOTE: When overriding this method, please be sure to call super.destroy(), otherwise the destroy call will not propagate. NOTE: Actually, the recursion, which destroys the elements should be here, because usually everybody forgets to call super.destroy when overriding, thus causing the destroy sceme to break down.

Specified by:

destroy in interface XFormsElement

Overrides:

destroy in class XSmilesElementImpl

getRefNode

public InstanceNode getRefNode()

Specified by:

getRefNode in interface ElementWithContext

getRef

public java.lang.String getRef()

getContextNode

getModel

public ModelElementImpl getModel()

Description copied from interface: ElementWithContext

get this elements model (look for parents if model attribute not found)

Specified by:

getModel in interface ElementWithContext

Overrides:

getModel in class XFormsElementImpl

notifyParentBindingChanged

public void notifyParentBindingChanged(DynBoundElementImpl ancestor)

notify that I should re-initialize my context node

Specified by:

notifyParentBindingChanged in interface ElementWithContext

renewBinding

public void renewBinding()

renew my bindings

Specified by:

renewBinding in interface ElementWithContext

checkBinding

public void checkBinding()

check if my binding has changed

Specified by:

checkBinding in interface ElementWithContext

hasBindingAttributes

public boolean hasBindingAttributes()

is this element bound. Not all elements are always bound, such as group without ref

Specified by:

hasBindingAttributes in interface ElementWithContext
