NAME

perfSONAR_PS::Datatypes::v2_0::nmtl3::Topology::Domain::Node::Port  - A base class, implements  'port'  element from the perfSONAR_PS RelaxNG schema
 

DESCRIPTION

Object representation of the port element.
Object fields are:
 Scalar:     id, 
 Object reference:   ipAddress => type HASH,

The constructor accepts only single parameter, it could be a hashref to parameters hash  or DOM with  'port' element 
 
 

SYNOPSIS

             use perfSONAR_PS::Datatypes::v2_0::nmtl3::Topology::Domain::Node::Port;
         
         my $el =  perfSONAR_PS::Datatypes::v2_0::nmtl3::Topology::Domain::Node::Port->new($DOM_Obj);

METHODS

new( )

creates   object, accepts DOM with  element tree or hashref to the list of
keyd parameters
   id   => undef, 
   ipAddress => HASH,

getDOM ($)

     accept parent DOM
     return port object DOM, generated from object contents 

querySQL ()

  depending on config  it will return some hash ref  to the initialized fields
for example querySQL ()
accepts one optional prameter - query hashref
will return:
{ ip_name_src =>  'hepnrc1.hep.net' },}

merge

merge with another port ( append + overwrite if exists )
we can do it differently
method #1:
   convert to dom both objects and then get resulted object from combined dom 
method #2 default:
   through the introspection of the object

buildIdMap()

if any of subelements has id then get a map of it in form of
hashref to { element}{id} = index in array and store in the idmap field

buildrefIdMap ()

if any of subelements has  metadataIdRef  then get a map of it in form of
hashref to { element}{ metadataIdRef } = index in array and store in the idmap field

asString()

shortcut to get DOM and convert into the XML string
returns XML string  representation of the  port object

registerNamespaces ()

will parse all subelements and register all namepspaces within the port namespace

fromDOM ($)

accepts parent XML DOM   element   tree as parameter 
returns port  object
