 Function: Creates a copy of the invocant object.
 Returns : A copy of the invocant.
 Args    : None.
 Comments: Cloning is currently experimental, use with caution.

contains()

Tests whether the invocant object contains the argument object.

 Type    : Test

           contains the argument object

 Args    : A Bio::Phylo::* object

cross_reference()

The cross_reference method links node and datum objects to the taxa they apply to. After crossreferencing a matrix with a taxa object, every datum object has a reference to a taxon object stored in its $datum->get_taxon field, and every taxon object has a list of references to datum objects stored in its $taxon->get_data field.

 Type    : Generic method
 Title   : cross_reference
 Usage   : $obj->cross_reference($taxa);
 Function: Crossreferences the entities 
           in the invocant with names 
           in $taxa
 Returns : string
 Args    : A Bio::Phylo::Taxa object
 Comments:

           entity in the invocant.

           index of the invocant.

 Args    : none.

delete()

 Type    : Object method
 Title   : delete
 Usage   : $obj->delete($other_obj);
 Function: Deletes an object from its container.
 Returns : A Bio::Phylo::Listable object.
 Args    : A Bio::Phylo::* object.
 Note    : Be careful with this method: deleting 
           a node from a tree like this will 
           result in undefined references in its 
           neighbouring nodes. Its children will 
           have their parent reference become 
           undef (instead of pointing to their 
           grandparent, as collapsing a node would 
           do). The same is true for taxon objects 
           that reference datum objects: if the 
           datum object is deleted from a matrix 
           (say), the taxon will now hold undefined 
           references.

first()

 Title   : first
 Usage   : my $first_obj = $obj->first;

           from a listable object.
 Returns : An entity stored by a listable 
           object (or array ref for slices).

           the way you dereference any perl
           array including through slices, 
           i.e. $obj->get_by_index(0 .. 10)>
           $obj->get_by_index(0, -1)

           $obj->set_namespaces( { 'dwc' => 'http://www.namespaceTBD.org/darwin2' } );
 Notes   : This is a global for the XMLWritable class, so that in a recursive
                   to_xml call the outermost element contains the namespace definitions.
                   This method can also be called as a static class method, i.e.

set_tag()

This method is usually only used internally, to define or alter the name of the tag into which the object is serialized.

 Returns : $self
 Args    : A tag name (must be a valid xml element name)

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.

 Usage   : my $phylo = Bio::Phylo->new;
 Function: Instantiates Bio::Phylo object
 Returns : a Bio::Phylo object

           * 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( );
