Meaning of operator ~> in Scala ?

Question

I'm trying to understand if this operator ( ~> ) means any in Scala or if it's domain specific?

I'm trying to understand the Scala code here. http://nlp.stanford.edu/software/tmt/tmt-0.4/examples/example-1-dataset.scala

Answer 1

~> has no special meaning in scala. In this case, it is just a method defined by ScalaNLP Breeze (See http://www.scalanlp.org/api/#breeze.text.tokenize.Tokenizer )
