Constructor Detail

NodeList

public NodeList()

Creates an instance.

NodeList

public NodeList(DomNode domNode,
                boolean attributeChangeSensitive)

Creates an instance.

Parameters:

domNode - the DomNode

attributeChangeSensitive - indicates if the content of the collection may change when an attribute of a descendant node of parentScope changes (attribute added, modified or removed)

NodeList

public NodeList(DomNode domNode,
                java.util.List<DomNode> initialElements)

Constructs an instance with an initial cache value.

Parameters:

domNode - the parent scope, on which we listen for changes

initialElements - the initial content for the cache

NodeList

NodeList(org.htmlunit.corejs.javascript.ScriptableObject parentScope)

Creates an instance.

Parameters:

parentScope - the parent scope

Method Detail

jsConstructor

public void jsConstructor()

JavaScript constructor.

staticNodeList

public static NodeList staticNodeList(HtmlUnitScriptable parentScope,
                                      java.util.List<DomNode> elements)

Gets a static NodeList.

Parameters:

parentScope - the parent scope

elements - the elements

Returns:

an empty collection

keys

public org.htmlunit.corejs.javascript.Scriptable keys()

Returns an Iterator allowing to go through all keys contained in this object.

Returns:

a NativeArrayIterator

values

public org.htmlunit.corejs.javascript.Scriptable values()

Returns an Iterator allowing to go through all keys contained in this object.

Returns:

a NativeArrayIterator

entries

public org.htmlunit.corejs.javascript.Scriptable entries()

Returns an Iterator allowing to go through all key/value pairs contained in this object.

Returns:

a NativeArrayIterator

forEach

public void forEach(java.lang.Object callback)

Calls the callback given in parameter once for each value pair in the list, in insertion order.

Parameters:

callback - function to execute for each element

getLength

public final int getLength()

Returns the length.

Overrides:

getLength in class AbstractList

Returns:

the length

item

public java.lang.Object item(java.lang.Object index)

Returns the item or items corresponding to the specified index or key.

Parameters:

index - the index or key corresponding to the element or elements to return

Returns:

the element or elements corresponding to the specified index or key
