public java.lang.Object call(Context cx, Scriptable scope, Scriptable thisObj, java.lang.Object[] args)
call in interface Callablecall in interface Functioncx - 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 argumentspublic Scriptable construct(Context cx, Scriptable scope, java.lang.Object[] args)
Functionnew operator. This method is
expected to create a new object and return it.public Scriptable createObject(Context cx, Scriptable scope)
construct(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, java.lang.Object[]) uses the method to
to get the value for thisObj argument when invoking
call(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, org.mozilla.javascript.Scriptable, java.lang.Object[]).
The methos is allowed to return null to indicate that
call(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, org.mozilla.javascript.Scriptable, java.lang.Object[]) will create a new object itself. In this case
construct(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, java.lang.Object[]) will set scope and prototype on the result
call(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable, org.mozilla.javascript.Scriptable, java.lang.Object[]) unless they are already set.public int getArity()
