NAME

Bio::Phylo - Phylogenetic analysis using perl

SYNOPSIS

 # Actually, you would almost never use this module directly. This is 
 # the base class for other modules.
 use Bio::Phylo;
 
 # sets global verbosity to 'error'
 Bio::Phylo->VERBOSE( -level => Bio::Phylo::Util::Logger::ERROR );
 
 # sets verbosity for forest ojects to 'debug'
 Bio::Phylo->VERBOSE( 
        -level => Bio::Phylo::Util::Logger::DEBUG, 
        -class => 'Bio::Phylo::Forest' 
 );

DESCRIPTION

This is the base class for the Bio::Phylo package for phylogenetic analysis using object-oriented perl5. In this file, methods are defined that are performed by other objects in the Bio::Phylo release that inherit from this base class (which you normally wouldn't use directly).

For general information on how to use Bio::Phylo, consult the manual (Bio::Phylo::Manual).

If you come here because you are trying to debug a problem you run into in using Bio::Phylo, you may be interested in the "exceptions" system as discussed in Bio::Phylo::Util::Exceptions. In addition, you may find the logging system in Bio::Phylo::Util::Logger of use to localize problems.

METHODS

CONSTRUCTOR

new()

The Bio::Phylo root constructor is rarely used directly. Rather, many other objects in Bio::Phylo internally go up the inheritance tree to this constructor. The arguments shown here can therefore also be passed to any of the child classes' constructors, which will pass them on up the inheritance tree. Generally, constructors in Bio::Phylo subclasses can process as arguments all methods that have set_* in their names. The arguments are named for the methods, but "set_" has been replaced with a dash "-", e.g. the method "set_name" becomes the argument "-name" in the constructor.

 Type    : Constructor
 Title   : new
 Usage   : my $phylo = Bio::Phylo->new;
 Function: Instantiates Bio::Phylo object
 Returns : a Bio::Phylo object 
 Args    : Optional, any number of setters. For example,
                   Bio::Phylo->new( -name => $name )
                   will call set_name( $name ) internally

MUTATORS

set_guid()

Sets invocant GUID.

 Type    : Mutator
 Title   : set_guid
 Usage   : $obj->set_guid($guid);
 Function: Assigns an object's GUID.
 Returns : Modified object.
 Args    : A scalar
 Notes   : This field can be used for storing an identifier that is
           unambiguous within a given content. For example, an LSID,
           a genbank accession number, etc.

set_desc()

Sets invocant description.

 Type    : Mutator
 Title   : set_desc
 Usage   : $obj->set_desc($desc);
 Function: Assigns an object's description.
 Returns : Modified object.
 Args    : Argument must be a string.

set_score()

Sets invocant score.

 Type    : Mutator
 Title   : set_score
 Usage   : $obj->set_score($score);
 Function: Assigns an object's numerical score.
 Returns : Modified object.
 Args    : Argument must be any of
           perl's number formats, or undefined
           to reset score.

set_generic()

Sets generic key/value pair(s).

 Type    : Mutator
 Title   : set_generic
 Usage   : $obj->set_generic( %generic );
 Function: Assigns generic key/value pairs to the invocant.
 Returns : Modified object.
 Args    : Valid arguments constitute:

           * key/value pairs, for example:
             $obj->set_generic( '-lnl' => 0.87565 );

           * or a hash ref, for example:
             $obj->set_generic( { '-lnl' => 0.87565 } );

           * or nothing, to reset the stored hash, e.g.
                $obj->set_generic( );

ACCESSORS

get_guid()

Gets invocant GUID.

 Type    : Accessor
 Title   : get_guid
 Usage   : my $guid = $obj->get_guid;
 Function: Assigns an object's GUID.
 Returns : Scalar.
 Args    : None
 Notes   : This field can be used for storing an identifier that is
           unambiguous within a given content. For example, an LSID,
           a genbank accession number, etc.

get_desc()

Gets invocant description.

 Type    : Accessor
 Title   : get_desc
 Usage   : my $desc = $obj->get_desc;
 Function: Returns the object's description (if any).
 Returns : A string
 Args    : None

get_score()

Gets invocant's score.

 Type    : Accessor
 Title   : get_score
 Usage   : my $score = $obj->get_score;
 Function: Returns the object's numerical score (if any).
 Returns : A number
 Args    : None

get_generic()

Gets generic hashref or hash value(s).

 Type    : Accessor
 Title   : get_generic
 Usage   : my $value = $obj->get_generic($key);
           or
           my %hash = %{ $obj->get_generic() };
 Function: Returns the object's generic data. If an
           argument is used, it is considered a key
           for which the associated value is returned.
           Without arguments, a reference to the whole
           hash is returned.
 Returns : A value or an array reference of values
 Args    : A key (string) or an array reference of keys

PACKAGE METHODS

get_obj_by_id()

Attempts to fetch an in-memory object by its UID

 Type    : Accessor
 Title   : get_obj_by_id
 Usage   : my $obj = Bio::Phylo->get_obj_by_id($uid);
 Function: Fetches an object from the IDPool cache
 Returns : A Bio::Phylo object 
 Args    : A unique id

clone()

Clones invocant.

 Type    : Utility method
 Title   : clone
 Usage   : my $clone = $object->clone;
 Function: Creates a copy of the invocant object.
 Returns : A copy of the invocant.
 Args    : None.
 Comments: Cloning is currently experimental, use with caution.
