  • Method Details

    • getToken

      DateValued getToken(int index)
      Description copied from interface: TokenSequence
      Gets the value at the specified position.
      Specified by:
      getToken in interface ScalarTokenSequence
      Specified by:
      getToken in interface TokenSequence
      Parameters:
      index - the index of the token
      Returns:
      the value

    • getDate

      @Deprecated Date getDate(int index)
      Deprecated.
      since 6.1; use getCalendarDate(int) instead to obtain an object representation of the date
      Gets the value of the specified token as a date.
      Parameters:
      index - the position of the token in the sequence
      Returns:
      the value of the token. If the token is null valued, null is returned.

    • getDate

      @Deprecated Date getDate(int index, ZoneId zoneId)
      Deprecated.
      since 6.1; use getCalendarDate(int) instead to obtain an object representation of the date
      Gets the value of the specified token as a date interpreted in the given timezone.
      Parameters:
      index - the index of the token
      zoneId - the timezone id relative to which to interpret the date.
      Returns:
      the value of the token. If the token is null valued, null is returned.

    • getEpochDays

      long getEpochDays(int index)
      Get the value of the specified token as the number of days elapsed since January 1, 1970 00:00:00 GMT.
      Parameters:
      index - the index of the token
      Returns:
      the value of the element. If the token is null valued, 0 is returned.

    • getCalendarDate

      CalendarDate getCalendarDate(int index)
      Gets the value of the specified token as a calendar date.
      Parameters:
      index - the position of the token in the sequence
      Returns:
      the value of the token. If the token is null valued, null is returned.

    • getValues

      void getValues(int start, long[] values, boolean[] nulls, int offset, int length)
      Gets the values and null indicators for a range of tokens.
      Parameters:
      start - the starting index of the range
      values - an array into which to place element values, represented as epoch days
      nulls - an array into which to place null indicator values
      offset - the starting offset into the target arrays. That is, elements[offset] and nulls[offset] will get the value and null indicator respectively of the token at position start, and so on.
      length - number of tokens to get

    • newValueIterator

      DateValuedIterator newValueIterator()
      Description copied from interface: TokenSequence
      Creates an iterator over the non-null values of this sequence. The iterator will automatically be reset as modifications are made to the sequence.
      Specified by:
      newValueIterator in interface ScalarTokenSequence
      Specified by:
      newValueIterator in interface TokenSequence
      Returns:
      an newly-created iterator over the non-null values of this sequence.
