Examples of org.jruby.embed.io.ReaderInputStream

org.jruby.embed.io.ReaderInputStream
A ReaderInputStream converts java.io.Reader to java.io.InputStream. The ReaderInputStream reads data in a given Reader object into its internal buffer so that users of this class can access the file that Reader read by using methods defined in java.io.InputStream. @author Yoko Harada
