equals

public boolean equals(Object other)

Description copied from class: RubyObject

This method is just a wrapper around the Ruby "==" method, provided so that RubyObjects can be used as keys in the Java HashMap object underlying RubyHash.

Overrides:

equals in class JavaAccessibleObject

hashCode

public int hashCode()

Description copied from class: RubyObject

Override the Object#hashCode method to make sure that the Ruby hash is actually used as the hashcode for Ruby objects. If the Ruby "hash" method doesn't return a number, the Object#hashCode implementation will be used instead.

Overrides:

hashCode in class JavaAccessibleObject
