Class MultiInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class MultiInputStream
extends java.io.InputStream
    This class is a facade on an array of InputStream. When the first InputStream is empty it reads in the next.

      • read

        public int read()
         throws java.io.IOException
        Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
        Specified by:
        read in class java.io.InputStream
        Returns:
        the next byte of data, or -1 if the end of the stream is reached.
        Throws:
        java.io.IOException - if an I/O error occurs.
        Since:
        JDK1.0

      • available

        public int available()
              throws java.io.IOException
        Returns the number of bytes that can be read from this input stream without blocking. The available method of InputStream returns 0. This method should be overridden by subclasses.
        Overrides:
        available in class java.io.InputStream
        Returns:
        the number of bytes that can be read from this input stream without blocking.
        Throws:
        java.io.IOException - if an I/O error occurs.
        Since:
        JDK1.0

      • close

        public void close()
           throws java.io.IOException
        Closes this input stream and releases any system resources associated with the stream.

        The close method of InputStream does nothing.

        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class java.io.InputStream
        Throws:
        java.io.IOException - if an I/O error occurs.
        Since:
        JDK1.0

      • mark

        public void mark​(int readlimit)
        Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.

        The readlimit arguments tells this input stream to allow that many bytes to be read before the mark position gets invalidated.

        Overrides:
        mark in class java.io.InputStream
        Parameters:
        readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
        Since:
        JDK1.0

        InputStream.reset()

      • markSupported

        public boolean markSupported()
        Tests if this input stream supports the mark and reset methods. The markSupported method of InputStream returns false.
        Overrides:
        markSupported in class java.io.InputStream
        Returns:
        true if this true type supports the mark and reset method; false otherwise.
        Since:
        JDK1.0

        InputStream.mark(int), InputStream.reset()
