Subject: Beginner Question (Idiomatic way to subset an array

I'm wondering if there is a more idiomatic way to do the following?
Can Array.collect be used to extract a subset of an array?

Peter

Can 

class ProcessInfo < Array
	
	def findByRealm(realm)
		result = ProcessInfo.new
		each { |process| 
			if process['realm'] == realm
		  		result << process
		  	end
		 }
		 return result
	end

end
