本文整理了Java中javax.jcr.query.Query.getStatement方法的一些代码示例，展示了Query.getStatement的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Query.getStatement方法的具体详情如下：
包路径：javax.jcr.query.Query
类名称：Query
方法名：getStatement

Query.getStatement介绍

[英]Returns the statement defined for this query.

If the language of this query is JCR-SQL2 or another string-based language, this method will return the statement that was used to create this query.

If the language of this query is JCR-JQOM, this method will return the JCR-SQL2 equivalent of the JCR-JQOM object tree. This is the standard serialization of JCR-JQOM and is also the string stored in the jcr:statement property if the query is persisted. See #storeAsNode(String).
[中]返回为此查询定义的语句。
如果此查询的语言是JCR-SQL2或其他基于字符串的语言，则此方法将返回用于创建此查询的语句。
如果这个查询的语言是JCR-JQOM，那么这个方法将返回JCR-SQL2等价于JCR-JQOM对象树。这是JCR-JQOM的标准序列化，如果查询被持久化，它也是jcr:statement属性中存储的字符串。请参见#storeAsNode（字符串）。
