Filter

public class CompositeColumnValueFilter
extends ColumnValueFilter

The filter used during TableStore query operations. CompositeColumnValueFilter is used to represent logical relationship conditions between ColumnValueFilters, which mainly include NOT, AND, and OR logical relationship conditions. Among them, NOT and AND indicate binary or multi-relationship conditions, while NOT only indicates a unary relationship.

The logical relationship is provided by the parameter in the constructor CompositeColumnValueFilter(CompositeColumnValueFilter.LogicOperator).

If the logical relationship is CompositeColumnValueFilter.LogicOperator.NOT, you can add a ColumnValueFilter through addFilter(ColumnValueFilter). The added ColumnValueFilter must be exactly one.

If the logical relationship is CompositeColumnValueFilter.LogicOperator.AND, you can add a ColumnValueFilter through addFilter(ColumnValueFilter). The added ColumnValueFilters must be greater than or equal to two.

If the logical relationship is CompositeColumnValueFilter.LogicOperator.OR, you can add a ColumnValueFilter through addFilter(ColumnValueFilter). The added ColumnValueFilters must be greater than or equal to two.
