32 /**
33  * <p>Represents a CFG for a {@link Body} instance where the nodes
34  * are {@link Block} instances, and where control flow associated with
35  * exceptions is taken into account. When dividing the {@link Body} into
36  * basic blocks,
37  * <code>CompleteBlockGraph</code> assumes that every {@link Unit} covered by a
38  * {@link Trap} has the potential to throw an
39  * exception caught by the {@link Trap}. This generally has the effect of
40  * separating every covered {@link Unit} into a separate block.
41  *
42  * <p>This implementation of <code>CompleteBlockGraph</code> is included
43  * for backwards compatibility, but the graphs it produces are not
44  * necessarily identical to the graphs produced by the implementation of
45  * <code>CompleteBlockGraph</code> See the documentation for
46  * {@link CompleteUnitGraph} for details of the incompatibilities.
