public class NodeCountInfoFilter
extends NewAbstractFilter
implements Comparator<Map.Entry<String,Integer>>

Field Details

counts

protected Map<String,Integer> counts

The node counts, Node Name -> Count

defMap

protected Map<String,String> defMap

Mapping between DEF and nodeName

Constructor Details

NodeCountInfoFilter

public NodeCountInfoFilter()

Construct a default instance of the filter.

Method Details

parseOutput

public Map<String,Integer> parseOutput(String txt)

Parse the output from this filter to get a map.

Parameters:

txt - The output

Returns:

The count map

endDocument

public void endDocument()
                 throws SAVException,
VRMLException

Declaration of the end of the document. There will be no further parsing and hence events after this.

Specified by:

endDocument in interface ContentHandler

Overrides:

endDocument in class NewAbstractFilter

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

startNode

public void startNode(String name,
 String defName)
               throws SAVException,
VRMLException

Notification of the start of a node. This is the opening statement of a node and it's DEF name. USE declarations are handled in a separate method.

Specified by:

startNode in interface ContentHandler

Overrides:

startNode in class NewAbstractFilter

Parameters:

name - The name of the node that we are about to parse

defName - The string associated with the DEF name. Null if not given for this node.

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

useDecl

public void useDecl(String defName)
             throws SAVException,
VRMLException

The field value is a USE for the given node name. This is a terminating call for startField as well. The next call will either be another startField() or endNode().

Specified by:

useDecl in interface ContentHandler

Overrides:

useDecl in class NewAbstractFilter

Parameters:

defName - The name of the DEF string to use

Throws:

SAVException - This call is taken at the wrong time in the structure of the document.

VRMLException - This call is taken at the wrong time in the structure of the document.

compare

public int compare(Map.Entry<String,Integer> o1,
 Map.Entry<String,Integer> o2)

Specified by:

compare in interface Comparator<Map.Entry<String,Integer>>
