Examples of org.apache.poi.poifs.filesystem.DocumentInputStream.available()

org.apache.poi.poifs.filesystem.DocumentInputStream.available()
Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or or another thread. @return the number of bytes that can be read from this inputstream without blocking. @exception IOException on error (such as the stream has beenclosed)
