<div class="block"><p>DirectedAcyclicGraph implements a DAG that can be modified (vertices &amp;
edges added and removed), is guaranteed to remain acyclic, and provides fast
topological order iteration.</p>
<p>This is done using a dynamic topological sort which is based on the
algorithm PK described in "D. Pearce &amp; P. Kelly, 2007: A Dynamic
Topological Sort Algorithm for Directed Acyclic Graphs", (see <a
href="http://www.mcs.vuw.ac.nz/~djp/files/PK-JEA07.pdf">Paper</a> or <a
href="http://doi.acm.org/10.1145/1187436.1210590">ACM link</a> for details).
</p>
<p>The implementation differs from the algorithm specified in the above paper
in some ways, perhaps most notably in that the topological ordering is stored
by default using two HashMaps, which will have some effects on runtime, but
also allows for vertex addition and removal, and other operations which are
helpful for manipulating or combining DAGs. This storage mechanism is
pluggable for subclassers.</p>
<p>This class makes no claims to thread safety, and concurrent usage from
multiple threads will produce undefined results.</p></div>
