Examples of java.io.InputStreamReader.ready()

java.io.InputStreamReader.ready()
Answers a boolean indicating whether or not this InputStreamReader is ready to be read without blocking. If the result is true, the next read() will not block. If the result is false this Reader may or may not block when read() is sent. This implementation answers true if there are bytes available in the buffer or the source InputStream has bytes available. @return true if the receiver will not block whenread() is called, false if unknown or blocking will occur. @throws IOException If the InputStreamReader is already closed or some other IO error occurs.
