public class BaseNCodecInputStream extends FilterInputStream
Abstract superclass for Base-N input streams.

    • BaseNCodecInputStream

      protected BaseNCodecInputStream(InputStream input, BaseNCodec baseNCodec, boolean doEncode)
  • Method Details

    • available

      public int available() throws IOException
      Overrides:
      available in class FilterInputStream
      Returns:
      0 if the InputStream has reached EOF, 1 otherwise
      Throws:
      IOException
      Since:
      1.7
    • isStrictDecoding

      public boolean isStrictDecoding()
      Returns true if decoding behavior is strict. Decoding will raise an IllegalArgumentException if trailing bits are not part of a valid encoding.

      The default is false for lenient encoding. Decoding will compose trailing bits into 8-bit bytes and discard the remainder.

      Returns:
      true if using strict decoding

    • mark

      public void mark(int readLimit)
      Marks the current position in this input stream.

      The mark(int) method of BaseNCodecInputStream does nothing.

      Overrides:
      mark in class FilterInputStream
      Parameters:
      readLimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
      Since:
      1.7
      See Also:
    • markSupported

      public boolean markSupported()
      Overrides:
      markSupported in class FilterInputStream
      Returns:
      Always returns false
    • read

      public int read() throws IOException
      Reads one byte from this input stream.
      Overrides:
      read in class FilterInputStream
      Returns:
      the byte as an integer in the range 0 to 255. Returns -1 if EOF has been reached.
      Throws:
      IOException - if an I/O error occurs.
    • read

      public int read(byte[] array, int offset, int len) throws IOException
      Attempts to read len bytes into the specified b array starting at offset from this InputStream.
      Overrides:
      read in class FilterInputStream
      Parameters:
      array - destination byte array
      offset - where to start writing the bytes
      len - maximum number of bytes to read
      Returns:
      number of bytes read
      Throws:
      IOException - if an I/O error occurs.
      NullPointerException - if the byte array parameter is null
      IndexOutOfBoundsException - if offset, len or buffer size are invalid
    • reset

      public void reset() throws IOException
      Repositions this stream to the position at the time the mark method was last called on this input stream.

      The reset() method of BaseNCodecInputStream does nothing except throw an IOException.

      Overrides:
      reset in class FilterInputStream
      Throws:
      IOException - if this method is invoked

    • skip

      public long skip(long n) throws IOException
      Overrides:
      skip in class FilterInputStream
      Throws:
      IllegalArgumentException - if the provided skip length is negative
      IOException
