ExpressionUtils.allOf介绍

[英]Create the intersection of the given arguments
[中]创建给定参数的交集

代码示例

private Predicate allOf(Collection<Predicate> predicates) {
  return predicates != null ? ExpressionUtils.allOf(predicates) : null;
}

代码示例来源：origin: spring-projects/spring-data-mongodb

private Predicate allOf(Collection<Predicate> predicates) {

}

代码示例来源：origin: querydsl/querydsl

/**
 * Create a {@code this or all(predicates)} expression
 *
 * <p>Return a union of this and the intersection of the given predicates</p>
 *
 * @param predicates intersection of predicates
 * @return this or all(predicates)
 */
