Examples of java.io.Reader.ready()

java.io.Reader.ready()
Answers a boolean indicating whether or not this Reader 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. @return true if the receiver will not block whenread() is called, false if unknown or blocking will occur. @throws IOException If the Reader is already closed or some other IO error occurs.
