Method Details

init

public static void init(Context cx,
 VarScope scope,
 boolean sealed)

getImplementation

public Object getImplementation()

initImplementation

public void initImplementation(Object implementation)

getClassName

public String getClassName()

Description copied from class: ScriptableObject

Return the name of the class.

This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

construct

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

Description copied from interface: Function

Call the function as a constructor.

This method is invoked by the runtime in order to satisfy a use of the JavaScript new operator. This method is expected to create a new object and return it.

If nt is equal to this then this call is equivalent `new f(...arguments), but reflection and super constructor calls may pass in different values.

Specified by:

construct in interface Constructable

Specified by:

construct in interface Function

Parameters:

cx - the current Context for this thread

nt - the new.target for this call,

scope - an enclosing scope of the caller except when the function is called from a closure.

args - the array of arguments

Returns:

the allocated object

call

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

Description copied from interface: Function

Call the function.

Note that the array of arguments is not guaranteed to have length greater than 0.

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

cx - the current Context for this thread

scope - the scope to execute the function relative to. This is set to the value returned by getParentScope() except when the function is called from a closure.

thisObj - the JavaScript this object

args - the array of arguments

Returns:

the result of the call

isContinuationConstructor

public static boolean isContinuationConstructor(JSFunction f)

equalImplementations

public static boolean equalImplementations(NativeContinuation c1,
 NativeContinuation c2)

Returns true if both continuations have equal implementations.

Parameters:

c1 - one continuation

c2 - another continuation

Returns:

true if the implementations of both continuations are equal, or they are both null.

Throws:

NullPointerException - if either continuation is null
