      Reads one byte at current file position and advances one position.
      Returns:
      Next byte of data or -1 if end of file is reached.

    • read

      public abstract int read(byte[] b) throws IOException
      Reads up to b.length bytes of data from this file into an array of bytes. This method blocks until at least one byte of input is available.
      Parameters:
      b - The buffer into which the data is read.
      Returns:
      The total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached.
      Throws:
      IOException - If the first byte cannot be read for any reason other than end of file, or if the file has been closed, or if some other I/O error occurs.

    • read

      public abstract int read(byte[] b, int off, int len) throws IOException
      Reads up to len bytes of data from this file into an array of bytes. This method blocks until at least one byte of input is available. This method behaves in exactly the same way as the InputStream.read(byte[], int, int) method of InputStream.
      Parameters:
      b - the buffer into which the data is read.
      off - the start offset in array b at which the data is written.
      len - the maximum number of bytes read.
      Returns:

      Throws:
      IOException - If the first byte cannot be read for any reason other than end of file, or if the random access file has been closed, or if some other I/O error occurs.

    • skip

      public abstract long skip(long n) throws IOException
      Attempts to skip over n byte of input discarding the skipped bytes.

      This method may skip over some number of bytes, possibly zero. This may result from any of a number of conditions; reaching end of file before n bytes have been skipped is only one possibility. The actual number of bytes skipped is returned. If n is negative, no bytes are skipped.

      Parameters:
      n - the number of bytes to be skipped.

      the actual number of bytes skipped.
      Throws:
      IOException - if an I/O error occurs.

      the offset from the beginning of the file, in bytes, at which the next read or write occurs.
      Throws:
      IOException - in an I/O error occurs.

    • isEndOfStream

      public abstract boolean isEndOfStream() throws IOException
      Determines whether end of file has been reached (next read() will return -1). or not.
      Returns:
      True if end of file has been reached, false otherwise.
      Throws:
      IOException - if an I/O error occurs.

    • seek

      public abstract void seek(long pos) throws IOException
      Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs. The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.
      Parameters:
      pos - the offset position, measured in bytes from the beginning of the file, at which to set the file pointer.
      Throws:

      public abstract boolean readBoolean() throws IOException
      Reads a boolean from this file. This method reads a single byte from the file, starting at the current file pointer. A value of 0 represents false. Any other value represents true. This method blocks until the byte is read, the end of the stream is detected, or an exception is thrown.

      Throws:
      IOException - if an I/O error occurs.

    • readLine

      public abstract String readLine() throws IOException
      Reads the next line of text from this file. This method successively reads bytes from the file, starting at the current file pointer, until it reaches a line terminator of the end of the file. Each byte is converted into a character by taking the byte's value for the lower eight bits of the character and setting the high eight bits of the character to zero. This method does not, therefore, support the full Unicode character set. A line of text is terminated by a carriage-return character ('\r'), a newline character('\n'), a carriage-return character immediately followed by a newline character, or the end of the file. Line-terminating characters are discarded and are not included as part of the string returned. This method blocks until a newline character is read, a carriage return and the byte following it are read (to see if it is a newline), the end of the file is reached, or an exception is thrown.
      Returns:

    • writeShort

      public abstract void writeShort(short v, EndianType endianType) throws IOException
      Writes a short to the file as two bytes using provided endian type. If endian type is big endian, then natural byte order is preserved (and high byte is written first), if little endian order is chosen, then byte order is reversed.
      Parameters:
      v - a short to be written.
      endianType - endian type. If it is big endian, natural byte order is preserved, otherwise byte order is reversed.
      Throws:
      IOException - if an I/O error occurs.
