Examples of java.io.InputStream.markSupported()

java.io.InputStream.markSupported()
Answers a boolean indicating whether or not this InputStream supports mark() and reset(). This class provides a default implementation which answers false. @return true if mark() and reset() are supported,false otherwise.
