Constructor Detail

SimpleArray

public SimpleArray()

Method Detail

item

public Object item(int index)

Returns the item at the given index.

Parameters:

index - the index

Returns:

the item at the given position

getWithPreemption

protected Object getWithPreemption(String name)

Called by HtmlUnitScriptable.get(String, Scriptable) to allow retrieval of the property before the prototype chain is searched.

IMPORTANT: This method is invoked *very* often by Rhino. If you override this method, the implementation needs to be as fast as possible!

Overrides:

getWithPreemption in class HtmlUnitScriptable

Parameters:

name - the property name

Returns:

Scriptable.NOT_FOUND if not found

get

public final Object get(int index,
                        org.htmlunit.corejs.javascript.Scriptable start)

Returns the element at the specified index, or null if the index is invalid.

Specified by:

get in interface org.htmlunit.corejs.javascript.Scriptable

Overrides:

get in class org.htmlunit.corejs.javascript.ScriptableObject

namedItem

public Object namedItem(String name)

Returns the item at the given index.

Parameters:

name - the item name

Returns:

the item with the given name

getItemName

protected String getItemName(Object element)

Gets the name of the element. Should be abstract but current implementation of prototype configuration doesn't allow it.

Parameters:

element - the array's element

Returns:

the element's name

getLength

public int getLength()

Gets the array size.

Returns:

the number elements
