Constructor Details

LiveComponent

public LiveComponent(RhinoScriptHandler handler,
 Obj xfaObject)

Instantiates a LiveComponent object. The lone constructor used by this package to create instances of this class.

Parameters:

handler - a Rhino script handler.

xfaObject - the XFA object associated with this component. Typically this is the application model.

Method Details

jsConstructor

public void jsConstructor(Object handler,
 Obj object)

Defines the JavaScript constructor to Rhino.

This method is required by the Scriptable interface and must mirror the signature of the class constructor.

Parameters:

handler - a Rhino script handler.

object - the XFA object associated with this component.

getClassName

public String getClassName()

Gets the name of the set of objects implemented by this class.

This method is required by the Scriptable interface.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

get

public Object get(String name,
 Scriptable start)

Gets the value of the named property of this object.

Specified by:

get in interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

name - the name of the property.

start - the object in which the lookup began.

Returns:

the value of the property, or NOT_FOUND if the property is not xfa nor a naked reference to an XFA property.

Throws:

EvaluatorException - whenever an ExFull was thrown while getting the XFA property.

See Also:

• Context.getUndefinedValue()

put

public void put(String name,
 Scriptable start,
 Object value)

Puts the value of the named property of the start object.

This method may (or not) set the property in the start object.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

name - the name of the property.

start - the object whose property is being set.

value - the value to set the property to.
