Bio::Phylo::NeXML::Writable - Superclass for objects that serialize to NeXML

 # no direct usage

This is the superclass for all objects that can be serialized to NeXML (http://www.nexml.org).

set_namespaces()

 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::NeXML::Writable->set_namespaces(
 		   'dwc' => 'http://www.namespaceTBD.org/darwin2');

set_suppress_ns()

 Type    : Mutator
 Title   : set_suppress_ns
 Usage   : $obj->set_suppress_ns();
 Function: Tell this object not to write namespace attributes
 Returns : 
 Args    : none

clear_suppress_ns()

 Type    : Mutator
 Title   : clear_suppress_ns
 Usage   : $obj->clear_suppress_ns();
 Function: Tell this object to write namespace attributes
 Returns : 
 Args    : none

add_meta()

 Type    : Mutator
 Title   : add_meta
 Usage   : $obj->add_meta($meta);
 Function: Adds a metadata attachment to the object
 Returns : $self
 Args    : A Bio::Phylo::NeXML::Meta object

remove_meta()

 Type    : Mutator
 Title   : remove_meta
 Usage   : $obj->remove_meta($meta);
 Function: Removes a metadata attachment from the object
 Returns : $self
 Args    : Bio::Phylo::NeXML::Meta

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_identifiable(0);
 Function: Enables/disables id generation
 Returns : $self
 Args    : BOOLEAN

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_name()

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. Ensure that this string is safe to use for
           whatever output format you want to use (this differs between xml and
           nexus, for example).

set_attributes()

Assigns attributes for the element.

 Type    : Mutator
 Title   : set_attributes
 Usage   : $obj->set_attributes( 'foo' => 'bar' )
 Function: Sets the xml attributes for the object;
 Returns : $self
 Args    : key/value pairs or a hash ref

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)

unset_attribute()

Removes specified attribute

 Type    : Mutator
 Title   : unset_attribute
 Usage   : $obj->unset_attribute( 'foo' )
 Function: Removes the specified xml attribute for the object
 Returns : $self
 Args    : an attribute name

get_namespaces()

 Type    : Accessor
 Title   : get_namespaces
 Usage   : my %ns = %{ $obj->get_namespaces };
 Function: Retrieves the known namespaces
 Returns : A hash of prefix/namespace key/value pairs, or
           a single namespace if a single, optional
           prefix was provided as argument
 Args    : Optional - a namespace prefix

get_meta()

Retrieves the metadata for the element.

 Type    : Accessor
 Title   : get_meta
 Usage   : my @meta = @{ $obj->get_meta };
 Function: Retrieves the metadata for the element.
 Returns : An array ref of Bio::Phylo::NeXML::Meta objects
 Args    : Optional: a list of CURIE predicates, in which case
           the returned objects will be those matching these
	   predicates

get_tag()

Retrieves tag name for the element.

 Type    : Accessor
 Title   : get_tag
 Usage   : my $tag = $obj->get_tag;

get_xml_id()

 Returns : a DOM element object (default XML::Twig)
 Args    : DOM factory object

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
