VERSION ^

This document describes Data::Compare::Type version 0.01.

SYNOPSIS ^

    use Data::Compare::Type;
    $v = Data::Compare::Type->new();
    $parameters = { id => 100};
    $rule = {id => 'INT'};
    $v->check($parameters , $rule)
    
    if($v->has_error){
        for my $error(@{$v->get_error}){
            die($error->{param_name} . ' is not ' . $error->{error});
        }
    }

Functions ^

check

  $v = Data::Compare::Type->new();
  $v->check(111 , "INT"); # return true
  $v->check(111 , "STRING"); # return false and $v->has_error is true 
  $v->check([111 , 1222, 333] , ["INT"]);# return true
  $v->check({ key  => 'value'},{key=> "ASCII"});# return true
  $v->check([{id => 111,id2=> 22.2 },{id=> 1222 , id2=> 1.11},{id=> 333 , id2=> 44.44}] , [{id =>"INT",id2 => "DECIMAL"}]);# return true

has_error

  $v->check(
    {key =>  "abcdefghijklmnop" },
    {key => ["ASCII","NOT_BLANK" , ['LENGTH' , 1 , 15]]});
  if($v->has_error){
      # error handling routine
  }

get_error

  $v->check(
    {key =>  "abcdefghijklmnop" },
    {key => ["ASCII","NOT_BLANK" , ['LENGTH' , 1 , 15]]});
  if($v->has_error){
      use Data::Dumper;
      warn Dumper $v->get_error;
      #$VAR1 = [
      #  {
      #    'min_value' => 1,
      #    'error' => 'LENGTH',
      #    'position' => '$param->{hoge}',
      #    'max_value' => 15,
      #    'param_name' => 'hoge',
      #    'message' => 'LENGTH IS WRONG'
      #  }
      #];
  }

 # allow integer ; 10 , 0 , -10
 ok $v->check(
    {key =>  "1" },

 ok $v->check(['a'] , $rule);
 ng $v->check(['abcdefghi'] , $rule);

 $rule = ["ASCII","NOT_BLANK" , ['LENGTH' , 4]];
 ng $v->check(['abc'] , $rule) # false
