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

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.

By default, all XMLWritable objects are identifiable when serialized, i.e. they have a unique id attribute. However, in some cases a serialized object may not have an id attribute (governed by the nexml schema). This method indicates whether that is the case.
Type : Test
Title : is_identifiable
Usage : if ( $obj->is_identifiable ) { ... }
Function: Indicates whether IDs are generated
Returns : BOOLEAN
Args : NONE

By default, all XMLWritable objects are identifiable when serialized, i.e. they have a unique id attribute. However, in some cases a serialized object may not have an id attribute (governed by the nexml schema). For such objects, id generation can be explicitly disabled using this method. Typically, this is done internally - you will probably never use this method.

This method can also be called as a static class method, i.e. Bio::Phylo::Util::XMLWritable->set_namespaces( 'dwc' => 'http://www.namespaceTBD.org/darwin2');
This method is usually only used internally, to define or alter the name of the tag into which the object is serialized. For example, for a Bio::Phylo::Forest::Node object, this method would be called with the 'node' argument, so that the object is serialized into an xml element structure called <node/>
Type : Mutator
Title : set_tag
Usage : $obj->set_tag('node');
Function: Sets the tag name
Returns : $self
Args : A tag name (must be a valid xml element name)
This method is usually only used internally, to store the xml id of an object as it is parsed out of a nexml file - this is for the purpose of round-tripping nexml info sets.

Usage : $obj->set_xml_id('node345');
Function: Sets the xml id
Returns : $self
Args : An xml id (must be a valid xml NCName)

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
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
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.
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( );
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, will be single
quoted if it contains [;|,|:\(|\)]
or spaces. Preceding and trailing spaces
will be removed.
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.
Serializes object to JSON string
Type : Serializer Title : to_json() Usage : print $obj->to_json(); Function: Serializes object to JSON string Returns : String Args : None Comments:
Serializes object to general purpose string
Type : Serializer Title : to_string() Usage : print $obj->to_string(); Function: Serializes object to general purpose string Returns : String Args : None Comments: This is YAML

Usage : my $taxon = $obj->get_taxon;
Function: Retrieves the Bio::Phylo::Taxa::Taxon
object linked to the invocant.
Returns : Bio::Phylo::Taxa::Taxon
Args : NONE
Comments:
Links the invocant object to a taxon object.

Title : set_taxon
Usage : $obj->set_taxon( $taxon );
Function: Links the invocant object
to a taxon object.
Returns : Modified $obj
Args : A Bio::Phylo::Taxa::Taxon object.
Unlinks the invocant object from any taxon object.

Usage : $obj->unset_taxon();
Function: Unlinks the invocant object
from any taxon object.
Returns : Modified $obj
Args : NONE
