Constructor Detail

BaseFunction

public BaseFunction(Scriptable scope, Scriptable prototype)

Method Detail

call

public Object call(Context cx, Scriptable scope, Scriptable thisObj, Object[] args)

Should be overridden.

construct

public Scriptable construct(Context cx, Scriptable scope, Object[] args)

createObject

public Scriptable createObject(Context cx, Scriptable scope)

Creates new script object. The default implementation of BaseFunction uses the method to to get the value for thisObj argument when invoking BaseFunction. The methos is allowed to return null to indicate that BaseFunction will create a new object itself. In this case BaseFunction will set scope and prototype on the result BaseFunction unless they are already set.
