      • getLength

        public int getLength()
        Description copied from interface: DataType
        Get the length (number of 8-bit bytes) of this DataType.
        Specified by:
        getLength in interface DataType
        Returns:
        the length of this DataType
      • getLength

        public int getLength​(MemBuffer buf,
                             int maxLength)
        Description copied from interface: Dynamic
        Compute the length for this data-type which corresponds to the specified memory location.
        Specified by:
        getLength in interface Dynamic
        Parameters:
        buf - memory location
        maxLength - maximum number of bytes to consume in computing length, or -1 for unspecified.
        Returns:
        data length or -1 if it could not be determined. Returned length may exceed maxLength if data-type does not supported constrained lengths.
      • canSpecifyLength

        public boolean canSpecifyLength()
        Description copied from interface: Dynamic
        Returns true if a user-specified length can be used
        Specified by:
        canSpecifyLength in interface Dynamic
      • clone

        public DataType clone​(DataTypeManager dtm)
        Description copied from interface: DataType
        Returns a new instance of this DataType with its universalID and SourceArchive identity retained. Note: for built-in DataType's, clone and copy should have the same affect.
        Specified by:
        clone in interface DataType
        Parameters:
        dtm - the data-type manager instance whose data-organization should apply.
      • getDescription

        public java.lang.String getDescription()
        Description copied from interface: DataType
        Get a String briefly describing this DataType.
        Specified by:
        getDescription in interface DataType
        Returns:
        a one-liner describing this DataType.
      • getRepresentation

        public java.lang.String getRepresentation​(MemBuffer buf,
                                                  Settings settings,
                                                  int length)
        Description copied from interface: DataType
        Get bytes from memory in a printable format for this type.
        Specified by:
        getRepresentation in interface DataType
        Parameters:
        buf - the data.
        settings - the settings to use for the representation.
        length - the number of bytes to represent.
        Returns:
        the representation of the data in this format, never null.
