Examples of javax.jdo.Query.declareImports()

javax.jdo.Query.declareImports()
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. @param imports import statements separated by semicolons.
