      • get

        public SegmentBody get​(SegmentHeader header)
        Description copied from interface: SegmentCache
        Returns a SegmentBody once the cache has returned any results, or null if no segment corresponding to the header could be found.

        Cache implementations are at liberty to 'forget' segments. Therefore it is allowable for this method to return null at any time

        Specified by:
        get in interface SegmentCache
        Parameters:
        header - The header of the segment to find. Consider this as a key.
        Returns:
        A SegmentBody, or null if no corresponding segment could be found in cache.
      • put

        public boolean put​(SegmentHeader header,
                           SegmentBody body)
        Description copied from interface: SegmentCache
        Stores a segment data in the cache.
        Specified by:
        put in interface SegmentCache
        Parameters:
        header - The header of the segment.
        body - The segment body to cache.
        Returns:
        Whether the cache write succeeded
      • getSegmentHeaders

        public List<SegmentHeader> getSegmentHeaders()
        Description copied from interface: SegmentCache
        Returns a list of all segments present in the cache.
        Specified by:
        getSegmentHeaders in interface SegmentCache
        Returns:
        A List of segment headers describing the contents of the cache.
      • remove

        public boolean remove​(SegmentHeader header)
        Description copied from interface: SegmentCache
        Removes a segment from the cache.
        Specified by:
        remove in interface SegmentCache
        Parameters:
        header - The header of the segment we want to remove.
        Returns:
        True if the segment was found and removed, false otherwise.
      • tearDown

        public void tearDown()
        Description copied from interface: SegmentCache
        Tear down and clean up the cache.
        Specified by:
        tearDown in interface SegmentCache
      • supportsRichIndex

        public boolean supportsRichIndex()
        Description copied from interface: SegmentCache
        Tells Mondrian whether this segment cache uses the SegmentHeader objects as an index, thus preserving them in a serialized state, or if it uses its identification number only.

        Not using a rich index prevents Mondrian from doing partial cache invalidation.

        It is assumed that this method returns fairly quickly, and for a given cache always returns the same value.

        Specified by:
        supportsRichIndex in interface SegmentCache
        Returns:
        Whether this segment cache preserves headers in serialized state
