BoundFunction

public BoundFunction(Context cx,
 VarScope scope,
 Callable targetFunction,
 Scriptable boundThis,
 Object[] boundArgs)

Method Details

call

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

Overrides:

call in class BaseFunction

construct

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

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

Overrides:

construct in class BaseFunction

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.

extraArgs - the array of arguments

Returns:

the allocated object

hasInstance

public boolean hasInstance(Scriptable instance)

Description copied from class: BaseFunction

Implements the instanceof operator for JavaScript Function objects.

foo = new Foo();
foo instanceof Foo; // true


Specified by:

hasInstance in interface Scriptable

Overrides:

hasInstance in class BaseFunction

Parameters:

instance - The value that appeared on the LHS of the instanceof operator

Returns:

true if the "prototype" property of "this" appears in value's prototype chain

getLength

public int getLength()

Overrides:

getLength in class BaseFunction

getFunctionName

public String getFunctionName()

Overrides:

getFunctionName in class BaseFunction
