[jgrapht-users] BlockCutpointGraph - getBlock

[Carl W. <wit...@st...>]

Hello JGraphT Users,

I have a question concerning the public UndirectedGraph 
<http://jgrapht.org/javadoc/org/jgrapht/UndirectedGraph.html><V 
<http://jgrapht.org/javadoc/org/jgrapht/alg/BlockCutpointGraph.html>,E 
<http://jgrapht.org/javadoc/org/jgrapht/alg/BlockCutpointGraph.html>> 
*getBlock*(V 
<http://jgrapht.org/javadoc/org/jgrapht/alg/BlockCutpointGraph.html> vertex) 
method.
The documentation says

     Returns the vertex if vertex is a cutpoint, and otherwise returns 
the block (biconnected component) containing the vertex.

But the example given in the introductory section of the 
BlockCutpointGraph class clarifies that the a vertex can be part of more 
than one block

     http://mathworld.wolfram.com/Block.html

Is the documentation of the getBlock method being imprecise (should it 
read "returns a block containing the vertex") or is the underlying 
definition of a block not the one from Mathworld?

Best regards,
Carl Witt
