Field Detail

instanceDoc

protected InstanceDocument instanceDoc

initialInstanceDoc

protected InstanceDocument initialInstanceDoc

Copy of the initial instance

href

protected java.lang.String href

lazyBastardMode

protected boolean lazyBastardMode

whether this was created using a bind to a non-existing instance

Constructor Detail

InstanceElementImpl

public InstanceElementImpl(XFormsElementHandler owner,
                           java.lang.String ns,
                           java.lang.String name)

Method Detail

init

public void init()

Description copied from class: XSmilesElementImpl

Initialize this element.

Specified by:

init in interface XFormsElement

Overrides:

init in class XFormsElementImpl

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

readInstanceAndReset

public void readInstanceAndReset(java.io.InputStream stream,
                                 java.net.URL url)

reset the instance document from this stream. Notify model that it should update all bindings etc.

Specified by:

readInstanceAndReset in interface InstanceElement

fetchInternalInstance

protected void fetchInternalInstance()

This function generates a new InstanceDocumentImpl, and copies the nodes under the internal instance to this new documentImpl

fetchExternalInstance

protected void fetchExternalInstance()
                              throws XFormsLinkException

read instance document from an external source

Throws:

XFormsLinkException

readInstanceFromStream

protected InstanceDocument readInstanceFromStream(java.io.InputStream stream,
                                                  java.net.URL url)
                                           throws XFormsLinkException

construct an instance document implementation from a stream

Throws:

XFormsLinkException

getInstanceNode

public org.w3c.dom.Node getInstanceNode()

getInstanceDocument

public InstanceDocument getInstanceDocument()

getInstanceAsString

public java.lang.String getInstanceAsString()
                                     throws org.xml.sax.SAXException

Creates a String with the data within the -element in it.

Returns:

a String: XML document with the instance data in it

Throws:

org.xml.sax.SAXException

copyInstance

protected InstanceDocument copyInstance(InstanceDocument doc)

Create a copy of the instance document

reset

public void reset()
           throws java.lang.Exception

reset this instance

Specified by:

reset in interface InstanceElement

Throws:

java.lang.Exception

getInstanceRoot

public org.w3c.dom.Node getInstanceRoot()

public method for ECMAScripts to get the root of the instance document

Specified by:

getInstanceRoot in interface XFormsInstanceElement

createLazyBastardElement

public void createLazyBastardElement(java.lang.String elementName,
                                     org.w3c.dom.Element owner)
                              throws XFormsBindingException

Throws:
