Method Details

createSimComponent(self, vertices, svs_data)

Creates simulation object from data.

This should be overidden by implementing classes.

endElement(self, name)

Signals the end of an element in non-namespace mode.

The name parameter contains the name of the element type, just as with the startElement event.

Overrides:: svs_core.filehandling.loaders.GenericXMLContentHandler.endElement (inherited documentation)

handlePathTag(self, attrs)

Parses PATH tag.

Parameters:: attrs - attributes for tag
(type=list)

handleRectTag(self, attrs)

Parses RECT tag.

Parameters:: attrs - attributes for tag
(type=list)

startElement(self, name, attrs)

Signals the start of an element in non-namespace mode.

The name parameter contains the raw XML 1.0 name of the element type as a string and the attrs parameter holds an instance of the Attributes class containing the attributes of the element.

Overrides:: svs_core.filehandling.loaders.GenericXMLContentHandler.startElement (inherited documentation)
