Examples with CGroup org.eclipse.elk.alg.layered.compaction.oned.CGroup used on opensource projects

Example 11 with CGroup

use of org.eclipse.elk.alg.layered.compaction.oned.CGroup in project elk by eclipse.

the class CompactionTest method testNoSpacingAppliedWithinGroups.

/**
 * Two separate groups, three nodes each.
 *
 * Care has to be taken when calculating the initial position of a {@link CGroup} not to include
 * any spacing between the group nodes. (Group nodes are rigidly fixed relative to each other
 * and thus no other spacing should be applied in between them). This test asserts that the
 * initial position of the groups is as expected.
