Method Detail

• adapt

  com.google.cloud.bigtable.data.v2.models.Filters.Filter adapt(FilterAdapterContext context,
                                                                S filter)
                                                         throws IOException

  Adapt the given filter. Implementers of this method should assume that isFilterSupported has already been called with a result indicating it is in fact supproted.

  Parameters:

  context - a FilterAdapterContext object.

  filter - a S object.

  Returns:

  a Filters.Filter object.

  Throws:

  IOException - if any.

• isFilterSupported

  FilterSupportStatus isFilterSupported(FilterAdapterContext context,
                                        S filter)

  Determine if the given filter can be adapted to a Bigtable RowFilter.

  Parameters:

  context - a FilterAdapterContext object.

  filter - a S object.

  Returns:

  a FilterSupportStatus object.

• getIndexScanHint

  RangeSet<RowKeyWrapper> getIndexScanHint(S filter)

  Get hints how to optimize the scan. For example if the filter will narrow the scan using the prefix "ab" then we can restrict the scan to ["ab" - "ac"). If the filter doesn't narrow the scan then it should return Range.all()

  Parameters:

  filter - a S object.

  Returns:

  a RangeSet object.
