Class SinkNodeAnalysis

java.lang.Object
 extended byptolemy.graph.analysis.Analysis
 extended byptolemy.graph.analysis.SinkNodeAnalysis

public class SinkNodeAnalysis
extends Analysis

Computation of sink nodes in a graph. A sink node in a graph is a node without output edges.

The returned collection cannot be modified when the client uses the default strategy.

Constructor Detail

SinkNodeAnalysis

public SinkNodeAnalysis(Graph graph)

Construct an instance of this class for a given graph.
Parameters:: graph - The given graph.

SinkNodeAnalysis

public SinkNodeAnalysis(ptolemy.graph.analysis.analyzer.SinkNodeAnalyzer analyzer)

Construct an instance of this class using a given analyzer.
Parameters:: analyzer - The given analyzer.

Method Detail

nodes

public java.util.List nodes()

Return the sink nodes in the graph under analysis. Each element of the list is an Node.

Returns:: Return the sink nodes.

toString

public java.lang.String toString()

Return a description of the analysis and the associated analyzer.

Overrides:: toString in class Analysis

Returns:: A description of the analysis and the associated analyzer.

validAnalyzerInterface

public boolean validAnalyzerInterface(ptolemy.graph.analysis.analyzer.Analyzer analyzer)

Check if a given analyzer is compatible with this analysis. In other words if it is possible to use it to compute the computation associated with this analysis.
