Direct Known Subclasses:

public class AdfIE8Agent
extends AdfIEAgentLegacy

AdfIE8Agent

public AdfIE8Agent(Object version,
                   Object domWindow)

IE8 AdfAgent AdfAgent capabilities. Eventually, we should probably refactor IEAgent into an base IEAgent and an IE7Agent. IE8Agent would then extend IEAgent Fixes for running on IE8

Parameters:

version
domWindow

addEventCaptures

public Object addEventCaptures(Object node,
                               Object listener)

IE 8 no longer supports style expressions. Instead, just leverage the standard event captures.

Parameters:

node
listener

Return:

Object

Overrides:

AdfAgent.addEventCaptures(Node, Function)

cloneNode

public Node cloneNode(Node domNode)

Clones a DOM node with default deep clone behavior for IE8. We have to override this method since IE8 is currently derived from IE7. This method can be removed after code refactory to let IE7 derive from IE8.

Parameters:

domNode

-

the DOM ndoe to clone the new node from

Return:

Node - the cloned DOM node.

Overrides:

AdfAgent.cloneNode(Node)

CreateDefaultLogWriter

protected Object CreateDefaultLogWriter(Object nativeLogWriter)

Creates and returns the default AdfLogWriter to use for this AdfPage. Subclassers should override CreateDefaultLogWriter instead

Parameters:

nativeLogWriter

Return:

Object

Overrides:

AdfAgent.createDefaultLogWriter()

elementsAdded

public Object elementsAdded(Object node)

Updates any id->element cache by adding the elements in the specified subtree IE7 has a bug with the getAttribute("id") fix, so this fix is moved to the AdfIE8Agent and a different approach is used for IE7 (in AdfIEAgent).

Parameters:

node

-

Either element or document node that is being added

Return:

Object

See also:

AdfAgent.getElementById(Object)

elementsRemoved(Object)

Overrides:

AdfAgent.elementsAdded(Object)

elementsRemoved

public Object elementsRemoved(Object node)

Updates any id->element cache by removing the elements in the specified subtree. IE7 has a bug with the getAttribute("id") fix, so this fix is moved to the AdfIE8Agent and a different approach is used for IE7 (in AdfIEAgent).

Parameters:

node

-

Either element or document node that is being removed

Return:

Object

AdfAgent.getElementById(Object)

elementsAdded(Object)

Overrides:

AdfAgent.elementsRemoved(Object)

Return:

Object

Overrides:

AdfAgent.getMaxConnectionsPerDomain()

getSessionStorageProperty

public String getSessionStorageProperty(String propKey)

key used to retrieve the value in storage

Return:

String - value of the property stored with key propKey

Throws:

Error if unable to set property to session storage
