Hi all,
I have been working with Rhino a bit lately, and I have a couple of
questions:
1) When a Java object is used in an equality expression, I expected
the JavaScript == operator to invoke the object's equals() method, and
=== to use Java's reference equality operator (==). However, it
appears that both == and === translate to reference equality; equals()
is only called if I invoke it explicitly. Is this the expected
behavior, or am I missing something?
2) If == does not currently delegate to equals(), should it? Taking
this one step further, would it be possible to support additional
operator overloads as well, a la Groovy?
http://groovy.codehaus.org/Operator+Overloading
For example, "a + b" translates to "a.plus(b)", "a - b" translates to
"a.minus(b)", etc.
Operator overloading is a feature that I have missed in Java (coming
from C++, way back) and many of the newer JVM scripting languages
support it (Groovy, Scala, JRuby (I think), and possibly others). It
would be really cool if Rhino supported it as well.
