所有已实现的接口:

ColumnCondition

public class CompositeColumnValueCondition
extends Object
implements ColumnCondition

Composite column value condition, used for the conditional update feature of TableStore. CompositeColumnValueCondition can combine logical conditions of SingleColumnValueCondition or CompositeColumnValueCondition, with three types of logical relationships: NOT, AND, and OR. Among them, NOT and AND represent binary or multi-element relationships, while NOT only represents a unary relationship.

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

If the logical relationship is CompositeColumnValueCondition.LogicOperator.NOT, you can add a ColumnCondition via addCondition(ColumnCondition), but only one ColumnCondition can be added.

If the logical relationship is CompositeColumnValueCondition.LogicOperator.AND, you can add a ColumnCondition via addCondition(ColumnCondition). The number of added ColumnConditions must be greater than or equal to two.

If the logical relationship is CompositeColumnValueCondition.LogicOperator.OR, you can add a ColumnCondition via addCondition(ColumnCondition), but the number of added ColumnConditions must be greater than or equal to two.
