[Simple-support] suggestion for re pattern checkers ...

[-=}\\*/{=- <rui...@gm...>]

hi,

it would be nice to be able configure RE pattern checkers for strings and
primitives...

// primitive
@Attribute (pattern="\d{2}")
int max99;



// string
@Attribute (pattern="\d{1,3}-\d{1,3}")
String range;

@Element (pattern="[a-zA-Z]{4,20}")
String firstName;

@Attribute (pattern="\p{Lower}{14}")
String username;



// object
@Element (pattern="[a-zA-Z]{4,20} [a-zA-Z]{4,20}")
FullName fn;

@Root
class FullName {

   String firstName,
   String lastName;
   // ...
   @FromString
   public void parse(String s) {...}

   @ToString // you may want to use the real toString for other stuff
   public String toString() {return firstName + " " + lastName;}
}


//
// the code bellow would be nicer though... no need to write parse code or
repeat patterns :)
//
// object
@Element (pattern="([a-zA-Z]{4,20}) ([a-zA-Z]{4,20})")
FullName fn;

// object
@Element (pattern="([a-zA-Z]{4,20}) ([a-zA-Z]{4,20})")
FullName fn;

@Root (asPrimitive = true)
class FullName {

   @Pattern (group = 0)
   String firstName,
   @Pattern (group = 1)
   String lastName;
   // ...
   @ToString
   public String toString() {return firstName + " " + lastName;}
}

... implied when reading and optional when writing...

think about it :)
