Examples of java.io.DataInputStream.available()

java.io.DataInputStream.available()
Returns the number of bytes that can be read from this input stream without blocking.
This method simply performs in.available() and returns the result. @return the number of bytes that can be read from the input streamwithout blocking. @exception IOException if an I/O error occurs.
