Troubleshootings with relationships

Precedence of geometry

The geometry option has always the priority on the others options. It means for instance that if it has a non-default value, then angle1, angle2 and loopsize options, defining recursive relations, will be ignored.

Attributes and alignment

The automatic placement of argument names and multiplicity on a relation can be surprising when you can to deactivate it. Let’s take the example Class diagram. If we focus on the association relation and its attributes toto and tata, toto is above, tata is below.

If we justify to the right the tata attribute (and change its position to 0.1), positions of tata and its multiplicity exchange.

\begin{umlpackage}{p}
\begin{umlpackage}{sp1}
\umlclass[template=T]{A}{
  n : uint \\ t : float
}{}
\umlclass[y=-3]{B}{
  d : double
}{
  \umlvirt{setB(b : B) : void} \\ getB() : B
}
\end{umlpackage}
\begin{umlpackage}[x=10, y=-6]{sp2}
\umlinterface{C}{
  n : uint \\ s : string
}{}
\end{umlpackage}
\umlclass[x=2, y=-10]{D}{
  n : uint
}{}
\end{umlpackage}

\umlassociate[geometry=-|-, arg1=tata, mult1=*, pos1=0.1, align1=right, arg2=toto, mult2=1, pos2=2.9, align2=left]{C}{B}
\umlunicompose[geometry=-|, arg=titi, mult=*, pos=1.7, stereo=vector]{D}{C}
\umlimport[geometry=|-, anchors=90 and 50, name=import]{sp2}{sp1}
\umlaggregate[arg=tutu, mult=1, pos=0.8, angle1=30, angle2=60, loopsize=2cm]{D}{D}
\umlinherit[geometry=-|]{D}{B}
\umlnote[x=2.5, y=-6, width=3cm]{B}{I am a note about B}
\umlnote[x=7.5, y=-2]{import-2}{I am a note about the import relation}
