Class jExists

  • All Implemented Interfaces:

    public class jExists
extends jStringComparisons
    A functor to test if a string exists. 
         $exists[A]
    this yields false if A is null or empty. IT yields true otherwise. Note that 
         $exists["   "]
    (a bunch of blanks) is true. If you wanted to check against a string of blanks you might use something like 
         $exists[$trim[A]]
    which would remove all the whitspace first.
