step

public void step()

Description copied from interface: StandardRepulsion

called from the layout algorithm on every step. this version is a noop but the subclass BarnesHut version rebuilds the tree on every step

Specified by:

step in interface StandardRepulsion<V,BarnesHutSpringRepulsion<V>,BarnesHutSpringRepulsion.Builder<V>>

Overrides:

step in class StandardSpringRepulsion<V,BarnesHutSpringRepulsion<V>,BarnesHutSpringRepulsion.Builder<V>>

calculateRepulsion

public void calculateRepulsion()

Specified by:

calculateRepulsion in interface StandardRepulsion<V,BarnesHutSpringRepulsion<V>,BarnesHutSpringRepulsion.Builder<V>>

Overrides:

calculateRepulsion in class StandardSpringRepulsion<V,BarnesHutSpringRepulsion<V>,BarnesHutSpringRepulsion.Builder<V>>
