NAME
Bio::Phylo::Taxa - Container of taxon objects
SYNOPSIS
use Bio::Phylo::Factory;
my $fac = Bio::Phylo::Factory->new;
# A mesquite-style default
# taxa block for 10 taxa.
my $taxa = $fac->create_taxa;
for my $i ( 1 .. 10 ) {
$taxa->insert( $fac->create_taxon( '-name' => "taxon_${i}" ) );
}
# prints a taxa block in nexus format
print $taxa->to_nexus;
DESCRIPTION
The Bio::Phylo::Taxa object models a set of operational taxonomic units. The object subclasses the Bio::Phylo::Listable object, and so the filtering methods of that class are available.
A taxa object can link to multiple forest and matrix objects.

INHERITED METHODS
Bio::Phylo::Taxa inherits from one or more superclasses. This means that objects of class Bio::Phylo::Taxa also "do" the methods from the superclasses in addition to the ones implemented in this class. Below is the documentation for those additional methods, organized by superclass.
SUPERCLASS Bio::Phylo::Listable
Bio::Phylo::Taxa inherits from superclass Bio::Phylo::Listable. Below are the public methods (if any) from this superclass.
- add_set()
-
Type : Mutator Title : add_set Usage : $obj->add_set($set) Function: Associates a Bio::Phylo::Set object with the invocant Returns : Invocant Args : A Bio::Phylo::Set object
- add_to_set()
-
Type : Mutator Title : add_to_set Usage : $listable->add_to_set($obj,$set); Function: Adds first argument to the second argument Returns : Invocant Args : $obj - an object to add to $set $set - the Bio::Phylo::Set object to add to Notes : this method assumes that $obj is already part of the invocant. If that assumption is violated a warning message is printed.
- can_contain()
-
Tests if argument can be inserted in invocant.
Type : Test Title : can_contain Usage : &do_something if $listable->can_contain( $obj ); Function: Tests if $obj can be inserted in $listable Returns : BOOL Args : An $obj to test
- clear()
-
Empties container object.
Type : Object method Title : clear Usage : $obj->clear(); Function: Clears the container. Returns : A Bio::Phylo::Listable object. Args : Note. Note :
- 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.
- contains()
-
Tests whether the invocant object contains the argument object.
Type : Test Title : contains Usage : if ( $obj->contains( $other_obj ) ) { # do something } Function: Tests whether the invocant object contains the argument object Returns : BOOLEAN 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:
- current()
-
Returns the current focal element of the listable object.
Type : Iterator Title : current Usage : my $current_obj = $obj->current; Function: Retrieves the current focal entity in the invocant. Returns : A Bio::Phylo::* object Args : none.

-
Returns the current internal index of the invocant.

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.

Returns : An entity stored by a listable object (or array ref for slices). Args : An index or range. This works the way you dereference any perl array including through slices, i.e. $obj->get_by_index(0 .. 10)> $obj->get_by_index(0, -1) and so on. Comments: Throws if out-of-bounds

Args : -value => any of the string datum props (e.g. 'get_type') -match => a compiled regular expression (e.g. qr/^[D|R]NA$/)
- get_by_value()
-
Gets elements that meet numerical rule from invocant container.
Type : Visitor predicate Title : get_by_value Usage : my @objects = @{ $obj->get_by_value( -value => $method, -ge => $number ) }; Function: Iterates through all objects contained by $obj and returns those for which the output of $method (e.g. get_tree_length) is less than (-lt), less than or equal to (-le), equal to (-eq), greater than or equal to (-ge), or greater than (-gt) $number.

- is_identifiable()
-
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

- set_identifiable()
-
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.

Type : Mutator Title : set_namespaces Usage : $obj->set_namespaces( 'dwc' => 'http://www.namespaceTBD.org/darwin2' ); Function: Adds one or more prefix/namespace pairs Returns : $self Args : One or more prefix/namespace pairs, as even-sized list, or as a hash reference, i.e.: $obj->set_namespaces( 'dwc' => 'http://www.namespaceTBD.org/darwin2' ); or $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. Bio::Phylo::Util::XMLWritable->set_namespaces( 'dwc' => 'http://www.namespaceTBD.org/darwin2');
- set_tag()
-
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)
- set_xml_id()

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

- 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
