    • DefaultDERBuffer

      public DefaultDERBuffer(byte[] array)
      Creates a new default DER buffer. See ByteBuffer.wrap(byte[]).

    • DefaultDERBuffer

      public DefaultDERBuffer(ByteBuffer buf)
      Creates a new default DER buffer.
      Parameters:
      buf - existing byte buffer
    • DefaultDERBuffer

      public DefaultDERBuffer(ByteBuffer buf, int pos, int lim)
      Creates a new default DER buffer and sets the initial position and limit.
      Parameters:
      buf - existing byte buffer
      pos - initial buffer position
      lim - initial buffer limit
  • Method Details

    • position

      public int position()
      Description copied from interface: DERBuffer
      Returns this buffer's position.
      Specified by:
      position in interface DERBuffer
      Returns:
      position of this buffer
    • position

      public DERBuffer position(int newPosition)
      Description copied from interface: DERBuffer
      Sets this buffer's position.
      Specified by:
      position in interface DERBuffer
      Parameters:
      newPosition - The new position value; must be non-negative and no larger than the current limit
      Returns:
      This buffer
    • limit

      public int limit()
      Description copied from interface: DERBuffer
      Returns this buffer's limit.
      Specified by:
      limit in interface DERBuffer
      Returns:
      limit of this buffer
    • capacity

      public int capacity()
      Description copied from interface: DERBuffer
      Returns this buffer's capacity.
      Specified by:
      capacity in interface DERBuffer
      Returns:
      capacity of this buffer
    • limit

      public DERBuffer limit(int newLimit)
      Description copied from interface: DERBuffer
      Sets this buffer's limit.
      Specified by:
      limit in interface DERBuffer
      Parameters:
      newLimit - The new limit value; must be non-negative and no larger than this buffer's capacity
      Returns:
      This buffer
    • clear

      public DERBuffer clear()
      Description copied from interface: DERBuffer
      Sets the position to zero and the limit to the capacity.

      This method does not actually erase the data in the buffer.

      Specified by:
      clear in interface DERBuffer
      Returns:
      This buffer
    • get

      public byte get()
      Description copied from interface: DERBuffer
      Relative get method. Reads the byte at this buffer's current position and then increments the position.
      Specified by:
      get in interface DERBuffer
      Returns:
      byte at the buffer's current position
    • get

      public DERBuffer get(byte[] dst)
      Description copied from interface: DERBuffer
      Relative bulk get method.
      Specified by:
      get in interface DERBuffer
      Parameters:
      dst - destination array
      Returns:
      This buffer
    • slice

      public DERBuffer slice()
      Description copied from interface: DERBuffer
      Creates a new DER buffer whose content is a shared sub-sequence of this buffer's content.

      The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position and limit will be independent.

      The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer.

      Specified by:
      slice in interface DERBuffer
      Returns:
      The new byte buffer
    • toString

      public String toString()
      Overrides:
      toString in class Object
