NAME

SPVM::Comparator::String - a callback interface for string comparation

SYNOPSYS

  use SPVM::Comparator::String;
  
  my $comparator : SPVM::Comparator::String = sub : int ($self : self, $a : string, $b : string); {
    return $a cmp $b;
  };
  
  my $result = $comparator->(3, 5);

DESCRIPTION

SPVM::Comparator::String is a callback interface to compare two strings.

CALLBACK METHOD INTERFACE

  sub : int ($self : self, $a : string, $b : string);

This method must receive two strings and return 1 if $a is more than $b, -1 if $x is less than $b, 0 if $a equals $b in the implementation.

This method is planned to be implemented in other classes.
