Constructor Detail

Storage

public Storage()

Public default constructor only for the prototype.

Storage

public Storage(Window window,
               Map<String,String> store)

Constructor.

Parameters:

window - the parent scope

store - the storage itself

Method Detail

jsConstructor

public void jsConstructor()

JavaScript constructor.

put

public void put(String name,
                org.htmlunit.corejs.javascript.Scriptable start,
                Object value)

Specified by:

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

Overrides:

put in class HtmlUnitScriptable

get

public Object get(String name,
                  org.htmlunit.corejs.javascript.Scriptable start)

Gets a named property from the object. Normally HtmlUnit objects don't need to overwrite this method as properties are defined on the prototypes from the XML configuration. In some cases where "content" of object has priority compared to the properties consider using utility HtmlUnitScriptable.getWithPreemption(String).

Specified by:

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

Overrides:

get in class HtmlUnitScriptable

getLength

public int getLength()

Returns the length property.

Returns:

the length property

removeItem

public void removeItem(String key)

Removes the specified key.

Parameters:

key - the item key

key

public String key(int index)

the key

getItem

public Object getItem(String key)

Returns the value of the specified key.

Parameters:
