filter
@NotNull public @NotNull WritableRowSet filter(@NotNull @NotNull RowSet selection, @NotNull @NotNull RowSet fullSet, @NotNull @NotNull Table table, boolean usePrev) Description copied from interface:WhereFilter
Filter selection to only matching rows.- Parameters:
selection
- the indices that should be filtered. The selection must be a subset of fullSet, and may include rows that the engine determines need not be evaluated to produce the result. Implementations may not mutate orclose
selection
.fullSet
- the complete RowSet of the table to filter. The fullSet is used for calculating variables like "i" or "ii". Implementations may not mutate orclose
fullSet
.table
- the table to filterusePrev
- true if previous values should be used. Implementing previous value filtering is optional, and aWhereFilter.PreviousFilteringNotSupported
exception may be thrown. If a PreviousFiltering exception is thrown, then the caller must acquire the PeriodicUpdateGraph lock.- Returns:
- The subset of selection accepted by this filter; ownership passes to the caller
-
filterInverse
@NotNull public @NotNull WritableRowSet filterInverse(@NotNull @NotNull RowSet selection, @NotNull @NotNull RowSet fullSet, @NotNull @NotNull Table table, boolean usePrev) Description copied from interface:WhereFilter
Filter selection to only non-matching rows.Defaults to
try (final WritableRowSet regular = filter(selection, fullSet, table, usePrev)) { return selection.minus(regular); }
Implementations are encouraged to override this when they can provide more efficient implementations.
- Parameters:
selection
- the indices that should be filtered. The selection must be a subset of fullSet, and may include rows that the engine determines need not be evaluated to produce the result. Implementations may not mutate orclose
selection
.fullSet
- the complete RowSet of the table to filter. The fullSet is used for calculating variables like "i" or "ii". Implementations may not mutate orclose
fullSet
.table
- the table to filterusePrev
- true if previous values should be used. Implementing previous value filtering is optional, and aWhereFilter.PreviousFilteringNotSupported
exception may be thrown. If a PreviousFiltering exception is thrown, then the caller must acquire the PeriodicUpdateGraph lock.- Returns:
- The subset of selection not accepted by this filter; ownership passes to the caller
-
copy
Description copied from interface:WhereFilter
Create a copy of this WhereFilter.- Returns:
- an independent copy of this WhereFilter.
