Class SelfLoopAnalysis

java.lang.Object

ptolemy.graph.analysis.Analysis

ptolemy.graph.analysis.SelfLoopAnalysis

public class SelfLoopAnalysis
extends Analysis

Computation of self-loops in a graph. A self-loop (also called a self-loop edge) in a graph is an edge whose source and sink nodes are identical.

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

Constructor Detail

SelfLoopAnalysis

public SelfLoopAnalysis(Graph graph)

Construct an instance of this class for a given graph.

Parameters:

graph - The given graph.

SelfLoopAnalysis

public SelfLoopAnalysis(SelfLoopAnalyzer analyzer)

Construct an instance of this class with a given analyzer.

Parameters:

analyzer - The analyzer to use.

Method Detail

edges

public java.util.List edges()

Return the self-loop edges in the graph under analysis. Each element of the list is an Edge.

Returns:

Return the self-loop edges.

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(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.

Overrides:

validAnalyzerInterface in class Analysis

Parameters:

analyzer - The given analyzer.

Returns:

True if the given analyzer is valid for this analysis.
