    • Method Detail

      • pushBack

        public void pushBack​(byte b)

      • isOpen

        public boolean isOpen()

      • readShortLE

        public final short readShortLE()
                        throws IOException
        Reads a signed 16-bit number from this stream in little-endian order. The method reads two bytes from this stream, starting at the current stream pointer. If the two bytes read, in order, are b1 and b2, where each of the two values is between 0 and 255, inclusive, then the result is equal to: 
             (short)((b2 << 8) | b1)

        This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown.

        Returns:
        the next two bytes of this stream, interpreted as a signed 16-bit number.
        Throws:
        EOFException - if this stream reaches the end before reading two bytes.
        IOException - if an I/O error occurs.

      • readUnsignedShortLE

        public final int readUnsignedShortLE()
                              throws IOException
        Reads an unsigned 16-bit number from this stream in little-endian order. This method reads two bytes from the stream, starting at the current stream pointer. If the bytes read, in order, are b1 and b2, where 0 <= b1, b2 <= 255, then the result is equal to: 
             (b2 << 8) | b1

        This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown.

        Returns:
        the next two bytes of this stream, interpreted as an unsigned 16-bit integer.
        Throws:
        EOFException - if this stream reaches the end before reading two bytes.
        IOException - if an I/O error occurs.

      • readCharLE

        public final char readCharLE()
                      throws IOException
        Reads a Unicode character from this stream in little-endian order. This method reads two bytes from the stream, starting at the current stream pointer. If the bytes read, in order, are b1 and b2, where 0 <= b1, b2 <= 255, then the result is equal to: 
             (char)((b2 << 8) | b1)

        This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown.

        Returns:
        the next two bytes of this stream as a Unicode character.
        Throws:
        EOFException - if this stream reaches the end before reading two bytes.
        IOException - if an I/O error occurs.

      • readIntLE

        public final int readIntLE()
                    throws IOException
        Reads a signed 32-bit integer from this stream in little-endian order. This method reads 4 bytes from the stream, starting at the current stream pointer. If the bytes read, in order, are b1, b2, b3, and b4, where 0 <= b1, b2, b3, b4 <= 255, then the result is equal to: 
             (b4 << 24) | (b3 << 16) + (b2 << 8) + b1

        This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown.

        Returns:
        the next four bytes of this stream, interpreted as an int.
        Throws:
        EOFException - if this stream reaches the end before reading four bytes.
        IOException - if an I/O error occurs.

      • readUnsignedInt

        public final long readUnsignedInt()
                           throws IOException
        Reads an unsigned 32-bit integer from this stream. This method reads 4 bytes from the stream, starting at the current stream pointer. If the bytes read, in order, are b1, b2, b3, and b4, where 0 <= b1, b2, b3, b4 <= 255, then the result is equal to: 
             (b1 << 24) | (b2 << 16) + (b3 << 8) + b4

        This method blocks until the four bytes are read, the end of the stream is detected, or an exception is thrown.

        Returns:
        the next four bytes of this stream, interpreted as a long.
        Throws:
        EOFException - if this stream reaches the end before reading four bytes.
        IOException - if an I/O error occurs.

      • getStartOffset

        public int getStartOffset()
        Getter for property startOffset.
        Returns:
        Value of property startOffset.

      • setStartOffset

        public void setStartOffset​(int startOffset)
        Setter for property startOffset.
        Parameters:
        startOffset - New value of property startOffset.
