NAME

Bio::Phylo::Matrices::Datatype::Rna - Validator subclass, no serviceable parts inside

DESCRIPTION

The Bio::Phylo::Matrices::Datatype::* classes are used to validate data contained by Bio::Phylo::Matrices::Matrix and Bio::Phylo::Matrices::Datum objects.

INHERITED METHODS

Bio::Phylo::Matrices::Datatype::Rna inherits from one or more superclasses. This means that objects of class Bio::Phylo::Matrices::Datatype::Rna 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.

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

set_gap()

           character, default is '-'

set_lookup()

Sets state lookup table.

 Type    : Mutator
 Title   : set_lookup
 Usage   : $obj->set_lookup($hashref);
 Function: Sets the state lookup table.
 Returns : Modified object.
 Args    : Argument must be a hash
           reference that maps allowed
           single character symbols
           (including ambiguity symbols)
           onto the equivalent set of
           non-ambiguous symbols

set_missing()

Sets missing data symbol.

 Type    : Mutator
 Title   : set_missing

 Function: Gets the xml tag for the object;
 Returns : A tag, i.e. pointy brackets
 Args    : Optional: a true value, to close an empty tag

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

 Function: Sets the xml attributes for the object;
 Returns : $self
 Args    : key/value pairs or a hash ref

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_identifiable
 Usage   : $obj->set_tag(0);
 Function: Enables/disables id generation
 Returns : $self
 Args    : BOOLEAN

set_namespaces()

 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)

to_xml()
