call
public Object call(Context cx,
Scriptable scope,
Scriptable thisObj,
Object[] args)
throws JavaScriptException
Call the function.
Note that the array of arguments is not guaranteed to have
length greater than 0.
- call in interface Callable
cx
- the current Context for this threadscope
- 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
objectargs
- the array of arguments
- the result of the call
JavaScriptException
- if an uncaught exception
occurred while executing the function
construct
public Scriptable construct(Context cx,
Scriptable scope,
Object[] args)
throws JavaScriptException
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.
cx
- the current Context for this threadscope
- an enclosing scope of the caller except
when the function is called from a closure.args
- the array of arguments
- the allocated object
JavaScriptException
- if an uncaught exception
occurred while executing the constructor
