本文整理了Java中javax.jdo.Query.declareImports方法的一些代码示例，展示了Query.declareImports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.declareImports方法的具体详情如下：
包路径：javax.jdo.Query
类名称：Query
方法名：declareImports

Query.declareImports介绍

[英]Set the import statements to be used to identify the fully qualified name of variables or parameters. Parameters and unbound variables might come from a different class from the candidate class, and the names need to be declared in an import statement to eliminate ambiguity. Import statements are specified as a String with semicolon-separated statements.

The String parameter to this method follows the syntax of the import statement of the Java language.
[中]设置用于标识变量或参数的完全限定名称的导入语句。参数和未绑定变量可能来自与候选类不同的类，需要在import语句中声明名称以消除歧义。导入语句被指定为String，语句之间用分号分隔。
此方法的String参数遵循Java语言的import语句的语法。
