createOrd (line 162)

Creates ordinal RDF resource out of an integer.

  • access: public
object Resource createOrd (Integer $num)
  • Integer $num

string getLocalName (Object $resource)
  • Object $resource: Resource $resource
getNamespace (line 49)

Extracts the namespace prefix out of the URI of a Resource.

  • access: public
string getNamespace (Object $resource)
  • Object $resource: Resource $resource
getOrd (line 144)

Converts an ordinal RDF resource to an integer.

e.g. Resource(RDF:_1) => 1

  • access: public
Integer getOrd (object Resource $resource)
  • object Resource $resource
getPrefix (line 87)

Short Prefix for known Namespaces by given URI

  • access: public
void getPrefix (String $uri)
  • String $uri
guessName (line 38)

Delivers the name out of the URI (without the namespace prefix).

  • access: public
string guessName (String $uri)
  • String $uri
guessNamespace (line 26)

Extracts the namespace prefix out of a URI.

  • access: public
string guessNamespace (String $uri)
  • String $uri
guessPrefix (line 337)

Short Prefix for known and/or parsed Namespaces by given URI and Model Uses $default_prefixes defined in constants.php and getParsedNamespaces() Returns FALSE if no matching prefix is found

string, guessPrefix (string $uri,  &$model, object $model)
  • string $uri
  • object $model
  • &$model
isRDF (line 116)

Tests if the URI of a resource belongs to the RDF syntax/model namespace.

  • access: public
boolean isRDF (Object $resource)
  • Object $resource: Resource $resource
visualizeGraph (line 382)

Generates a dot-file for drawing graphical output with the

graphviz-application which can be downloaded at http://www.graphviz.org If the graphviz-application is installed and its path is set to the correct value in constants.php we can directly generate any file format graphviz supports, e.g. SVG, PNG Parameters: model to visualize, output format, use prefixes

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! WARNING: Graphviz can be slow with large models. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

string, visualizeGraph (object Model &$model, [string $format = "input_dot"], [boolean $short_prefix = TRUE])
  • string $format
  • boolean $short_prefix
  • object Model &$model
writeHTMLTable (line 173)

Prints a MemModel as HTML table.
