Bio::Phylo::ListableRole - Extra functionality for things that are lists

No direct usage, parent class. Methods documented here are available for all objects that inherit from it.

A listable object is an object that contains multiple smaller objects of the same type. For example: a tree contains nodes, so it's a listable object.
This class contains methods that are useful for all listable objects: Matrices (i.e. sets of matrix objects), individual Matrix objects, Datum objects (i.e. character state sequences), Taxa, Forest, Tree and Node objects.

Prunes the container's contents specified by an array reference of indices.
Type : Mutator Title : prune_entities Usage : $list->prune_entities([9,7,7,6]); Function: Prunes a subset of contents Returns : A Bio::Phylo::Listable object. Args : An array reference of indices
Returns the index of the argument in the list, or undef if the list doesn't contain the argument
Type : Accessor
Title : get_index_of
Usage : my $i = $listable->get_index_of($obj)
Function: Returns the index of the argument in the list,
or undef if the list doesn't contain the argument
Returns : An index or undef
Args : A contained object
Gets element at index from container.
Type : Accessor
Title : get_by_index
Usage : my $contained_obj = $obj->get_by_index($i);
Function: Retrieves the i'th entity
from a listable object.
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
Gets elements that match regular expression from container.
Type : Accessor
Title : get_by_regular_expression
Usage : my @objects = @{
$obj->get_by_regular_expression(
-value => $method,
-match => $re
) };
Function: Retrieves the data in the
current Bio::Phylo::Listable
object whose $method output
matches $re
Returns : A list of Bio::Phylo::* objects.
Args : -value => any of the string
datum props (e.g. 'get_type')
-match => a compiled regular
expression (e.g. qr/^[D|R]NA$/)
Gets elements that meet numerical rule from container.
Type : Accessor
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.
Returns : A reference to an array of objects
Args : -value => any of the numerical
obj data (e.g. tree length)
-lt => less than
-le => less than or equals
-eq => equals
-ge => greater than or equals
-gt => greater than
Gets first element that has argument name
Type : Accessor
Title : get_by_name
Usage : my $found = $obj->get_by_name('foo');
Function: Retrieves the first contained object
in the current Bio::Phylo::Listable
object whose name is 'foo'
Returns : A Bio::Phylo::* object.
Args : A name (string)
Iterates over objects contained by container, executes argument code reference on each.
Type : Visitor predicate
Title : visit
Usage : $obj->visit(
sub{ print $_[0]->get_name, "\n" }
);
Function: Implements visitor pattern
using code reference.
Returns : The container, possibly modified.
Args : a CODE reference.
Tests whether the container object contains the argument object.
Type : Test
Title : contains
Usage : if ( $obj->contains( $other_obj ) ) {
# do something
}
Function: Tests whether the container object
contains the argument object
Returns : BOOLEAN
Args : A Bio::Phylo::* object
Tests if argument can be inserted in container.
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
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 container with names
in $taxa
Returns : string
Args : A Bio::Phylo::Taxa object
Comments:
Sorts the contents alphabetically by their name.
Type : Generic method Title : alphabetize Usage : $obj->alphabetize; Function: Sorts the contents alphabetically by their name. Returns : $self Args : None Comments:
Many Bio::Phylo objects are segmented, i.e. they contain one or more subparts of the same type. For example, a matrix contains multiple rows; each row contains multiple cells; a tree contains nodes, and so on. (Segmented objects all inherit from Bio::Phylo::Listable, i.e. the class whose documentation you're reading here.) In many cases it is useful to be able to define subsets of the contents of segmented objects, for example sets of taxon objects inside a taxa block. The Bio::Phylo::Listable object allows this through a number of methods (add_set, remove_set, add_to_set, remove_from_set etc.). Those methods delegate the actual management of the set contents to the Bio::Phylo::Set object. Consult the documentation for Bio::Phylo::Set for a code sample.
Returns string representation of sets
Type : Accessor Title : sets_to_xml Usage : my $str = $obj->sets_to_xml; Function: Gets xml string Returns : Scalar Args : None

Iterate over a set of trees.
Iterate over nodes in a tree.
Iterate of children of a node.
Iterate over a set of matrices.
Iterate over the datum objects in a matrix.
Iterate over the characters in a datum.
Iterate over a set of taxa.
This object inherits from Bio::Phylo::NeXML::Writable, so methods defined there are also applicable here.
