getColumns
Description copied from interface:WhereFilter
Get the columns required by this select filter.This filter must already be initialized before calling this method.
- Returns:
- the columns used as input by this select filter.
-
getColumnArrays
Description copied from interface:WhereFilter

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
-
isSimpleFilter
public boolean isSimpleFilter()- Returns:
- true if this is a filter that does not require any code execution, but rather is handled entirely within the database engine.
-
setRecomputeListener
Description copied from interface:WhereFilter
Set theWhereFilter.RecomputeListener
that should be notified if results based on this WhereFilter must be recomputed.- Parameters:
listener
- TheWhereFilter.RecomputeListener
to notify
