NAME

Bio::Tools::ECnumber - representation of EC numbers (Enzyme Classification)

SYNOPSIS

use Bio::Tools::ECnumber;

# Creation of ECnumber objects
my $EC1 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.1" );
my $EC2 = Bio::Tools::ECnumber->new( -ec_string => "EC 1.1.1.1" );
my $EC3 = Bio::Tools::ECnumber->new();

# Copying
my $EC4 = $EC1->copy();

# Modification/canonicalization of ECnumber objects
print $EC3->EC_string( "1.01.01.001" ); # Prints "1.1.1.1".

# Stringify
print $EC3->EC_string();
# or
print $EC3->to_string();

# Test for equality
# -- Against ECnumber object:
if ( $EC3->is_equal( $EC2 ) ) { # Prints "equal".
    print "equal";
}
# -- Against string representation of EC number:
if ( ! $EC3->is_equal( "1.1.1.-" ) ) { # Prints "not equal".
    print "not equal";
}

# Test for membership
my $EC5 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.-" ); 
# -- Against ECnumber object.
if ( $EC1->is_member( $EC5 ) ) { # Prints "member".
    print "member"; 
}
# -- Against string representation of EC number.
if ( ! $EC1->is_member( "4.3.1.-" ) ) { # Prints "not member".
    print "not member";
}

DESCRIPTION

Bio::Tools::ECnumber is a representation of EC numbers, the numerical hierarchy for Enzyme Classification.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

new

Title   : new
Usage   : $EC1 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.1" );
          or
          $EC2 = Bio::Tools::ECnumber->new( -ec_string => "4.3.2.2",
                                            -comment   => "Is EC 4.3.2.2" );
          or                      
          $EC3 = Bio::Tools::ECnumber->new(); # EC3 is now "-.-.-.-"                      
Function: Creates a new ECnumber object.
          Parses a EC number from "x.x.x.x", "EC x.x.x.x",
          "ECx.x.x.x", or "EC:x.x.x.x";
          x being either a positive integer or a "-".
Returns : A new ECnumber object.
Args    : A string representing a EC number, e.g. "4.3.2.1"
          or "EC 4.3.2.1" or "1.-.-.-".

init

Title   : init()
Usage   : $EC1->init(); # EC1 is now "-.-.-.-"    
Function: Initializes this ECnumber to default values.
Returns : 
Args    :

copy

Title   : copy()
Usage   : $EC2 = $EC1->copy();
Function: Creates a new ECnumber object which is an exact copy
          of this ECnumber.
Returns : A copy of this ECnumber.
Args    :

EC_string

Title   : EC_string
Usage   : $EC3->EC_string( "1.1.1.-" );
          or
          print $EC3->EC_string();
Function: Set/get for string representations of EC numbers.
          Parses a EC number from "x.x.x.x", "EC x.x.x.x",
          "ECx.x.x.x", or "EC:x.x.x.x";
          x being either a positive integer or a "-".
Returns : A string representations of a EC number.
Args    : A string representations of a EC number.

to_string

Title   : to_string()
Usage   : print $EC3->to_string();
Function: To string method for EC numbers
          (equals the "get" functionality of "EC_string").
