Query.cloneQuery介绍

[英]Makes a copy of this query. Copies by parsing a query from the serialized form of this query
[中]复制此查询。通过分析此查询的序列化形式中的查询进行复制

代码示例

/**
 * Make a query from another one by deep copy (a clone).
 * The returned query will be .equals to the original.
 * The returned query can be mutated without changing the
 * original (at which point it will stop being .equals)
 * 
 * @param originalQuery  The query to clone.
 *
