        public OtherByteAttributeMultipleCompressedFrames​(AttributeTag t,
                                                          byte[] allframes)

        Construct an attribute from a single byte array containing all compressed frames.

        The VL is not required, since it is undefined by definition.

        Parameters:
        t - the tag of the attribute
        allframes - the frames

                                                          byte[][] frames)

        Construct an attribute from a set of compressed frames.

        The VL is not required, since it is undefined by definition.

        Parameters:
        t - the tag of the attribute
        frames - the frames

        Construct an attribute from a set of compressed frames.

        The VL is not required, since it is undefined by definition.

        Parameters:
        t - the tag of the attribute
        files - the files containing the compressed bit streams

        Description copied from class: Attribute

        Write the entire attribute (including values) to the output stream.

        Specified by:
        write in class Attribute
        Parameters:
        o -
        Throws:
        java.io.IOException

      • getFrames

        public byte[][] getFrames()

        Get the byte arrays for each frame.

        Returns:
        an array of byte arrays for each frame
      • toString

        public java.lang.String toString​(DicomDictionary dictionary)
        Description copied from class: Attribute

        Dump the contents of the attribute as a human-readable string.

        No new line is appended.

        The result is of the form:

         (0xgggg,0xeeee) Name VR=<XX> VL=<0xnnnn> <...>
         

        For example:

         (0x0018,0x0020) ScanningSequence VR=<CS> VL=<0x2> <GR>
         
        Overrides:
        toString in class Attribute
        Parameters:
        dictionary - the dictionary to use to look up the name
        Returns:
        a single String value
      • removeValues

        public void removeValues()
        Description copied from class: Attribute

        Remove any existing values, making the attribute empty (zero length).

        Specified by:
        removeValues in class Attribute
      • getVR

        public byte[] getVR()

        Get the value representation of this attribute (OB).

        Overrides:
        getVR in class Attribute
        Returns:
        'O','B' in ASCII as a two byte array; see ValueRepresentation
