Method Detail

init

public void init(org.graphstream.graph.Graph graph)

Description copied from interface: Algorithm

Initialization of the algorithm. This method has to be called before the Algorithm.compute() method to initialize or reset the algorithm according to the new given graph.

Specified by:

init in interface Algorithm

Parameters:

graph - The graph this algorithm is using.

compute

public void compute()

Description copied from interface: Algorithm

Run the algorithm. The Algorithm.init(Graph) method has to be called before computing.

Specified by:

compute in interface Algorithm

See Also:

Algorithm.init(Graph)

copyValuesTo

public void copyValuesTo(String attribute)

Copy values previously computed to a specific attribute. The compute() method needs to have been call before calling this one.

Parameters:

attribute - destination attribute where values of centrality will be stored

copyValuesTo

public void copyValuesTo(String attribute,
                AbstractCentrality.NormalizationMode normalize)

Copy values previously computed to a specific attribute. The compute() method needs to have been call before calling this one.

Parameters:

attribute - destination attribute where values of centrality will be stored

normalize - defines the way that values have to be normalized

getCentralityAttribute

public String getCentralityAttribute()

Getter for centralityAttribute.

Returns:

centralityAttribute

setCentralityAttribute

public void setCentralityAttribute(String centralityAttribute)

Setter for centralityAttribute.

Parameters:

centralityAttribute - new value of centralityAttribute

getNormalizationMode

public AbstractCentrality.NormalizationMode getNormalizationMode()

Getter for normalize.

Returns:

normalize

setNormalizationMode

public void setNormalizationMode(AbstractCentrality.NormalizationMode normalize)

Setter for normalize.

Parameters:

normalize - new value of normalize
