      void write​(int b)
      Writes the specified byte to this byte array output stream.

    • Field Detail

      • buf

        protected byte[] buf
        The buffer where data is stored.

      • count

        protected int count
        The number of valid bytes in the buffer.

      • startOffset

        protected long startOffset

    • Constructor Detail

      • DiscardingByteArrayOutputStream

        public DiscardingByteArrayOutputStream()
        Creates a new byte array output stream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

      • DiscardingByteArrayOutputStream

        public DiscardingByteArrayOutputStream​(int size)
        Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.
        Parameters:
        size - the initial size.
        Throws:
        IllegalArgumentException - if size is negative.

    • Method Detail

      • get

        public byte[] get​(long start,
                  int count)

      • write

        public void write​(int b)
        Writes the specified byte to this byte array output stream.
        Specified by:
        write in class OutputStream
        Parameters:
        b - the byte to be written.

      • write

        public void write​(byte[] b,
                  int off,
                  int len)
        Writes len bytes from the specified byte array starting at offset off to this byte array output stream.
        Overrides:
        write in class OutputStream
        Parameters:
        b - the data.
        off - the start offset in the data.
        len - the number of bytes to write.

      • reset

        public void reset()
        Resets the count field of this byte array output stream to zero, so that all currently accumulated output in the output stream is discarded. The output stream can be used again, reusing the already allocated buffer space.
        See Also:
        ByteArrayInputStream.count

      • toByteArray

        public byte[] toByteArray()
        Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.
        Returns:
        the current contents of this output stream, as a byte array.
        See Also:
        ByteArrayOutputStream.size()

      • size

        public int size()
        Returns the current size of the buffer.
        Returns:
        the value of the count field, which is the number of valid bytes in this output stream.
        See Also:
        ByteArrayOutputStream.count

      • toString

        public String toString()
        Converts the buffer's contents into a string decoding bytes using the platform's default character set. The length of the new String is a function of the character set, and hence may not be equal to the size of the buffer. This method always replaces malformed-input and unmappable-character sequences with the default replacement string for the platform's default character set. The CharsetDecoder class should be used when more control over the decoding process is required.
        Overrides:
        toString in class Object
        Returns:
        String decoded from the buffer's contents.
        Since:
        JDK1.1

      • close

        public void close()
           throws IOException
        Closing a ByteArrayOutputStream has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.
        Specified by:
        close in interface AutoCloseable
        Specified by:
        close in interface Closeable
        Overrides:
        close in class OutputStream
        Throws:
        IOException

      • available

        public long available()
        Returns the last index that is available.
        Returns:
        the overall size (not taking discarded bytes into account)

      • discardTo

        public void discardTo​(long n)
