You aren't using any class-level
members in your static methods so you should be fine.
This means that I cannot declare a:
public class Data {
private static DataSource datasource = null;
public static DataSource getDataSource() {
if (datasource == null) {
// create a datasource
}
return datasource;
}
}
In the code above the class-level member is the datasource.
Do you mean I should do like this instead:
public class Data {
public static DataSource getDataSource() {
// create a new datasource for each call to this method
return datasource;
}
}
