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_name()

Sets invocant name.

 Type    : Mutator
 Title   : set_name
 Usage   : $obj->set_name($name);
 Function: Assigns an object's name.
 Returns : Modified object.
 Args    : Argument must be a string. Ensure that this string is safe to use for
           whatever output format you want to use (this differs between xml and
           nexus, for example).

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
