If you have multiple self-links at a node, they are bundled
like multilinks. The bends of the self-links are shifted to avoid
self-links overlapping each other. The multiself-links can be distributed
in relation to the attachment position in various ways. The specified
attachment position refers to the middle of the bundle, or it refers
to the outermost link of the bundle, or it refers to the innermost
link of the bundle. This is illustrated by the following figures.
The attachment position is the same in all three cases and is indicated
by the two small crosses (X), but the multiself-link distribution
is variously centered, toward the inside of the bundle, or toward
the outside of the bundle.

Multiself-link distribution
Use o método:
layout.setMultiSelfLinkDistribution(distribution);
The valid values for distribution are
given with the example of Force-directed layout:
The offset between the bends of the self-links can be
specified. These parameters have the same meaning as the corresponding
parameters on general multilinks, but apply only to self-links that
are multilink bundles.
Use os métodos:
layout.setMultiSelfLinkOffset(offset); layout.setMultiSelfLinkMaxSpread(maxSpread);
The multiself-link offset is the offset between two neighboring
self-links (or their bends). The value of maxSpread limits
this offset to avoid having too much space used when you have too
many multiple self-links. If the multiself-link offset is 10 and the
value of maxSpread is 60, the effective
offset is 10 if you have less than six multiself-links. If you have
more multiself-links, the effective offset is reduced. For example,
if you have 15 multiself-links, the effective offset will be 4 instead
of 10 to ensure that the self-links are shifted at most 60 units apart
from each other. If the self-link mode is one of the narrow modes,
for example, NARROW_CONNECTED_RECTANGULAR,
the effective offset is further limited by the size of the bounding
box of the node where the self-links occur.
