java - How do you determine the type of data contained in a string? -


I have a method that accepts string logic.

An integer in the string, double, boolean, or just plain old letters and numbers.

I want an easy way to determine what type of string is.

There is a way to catch a bunch of blocks and try to parse it in every type, and if an exception is thrown, then it is probably not that data type. It seems incorrect because it is an intuitive program, not a deterministic program.

If you know how to once you enter the parameter You know, it is ok to parse that type of string and catch the exception - it's fair use of exceptions to capture invalid data (unless you're just trying one type ..)

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
