Examples with LabelSide org.eclipse.elk.core.options.LabelSide used on opensource projects

Example 1 with LabelSide

use of org.eclipse.elk.core.options.LabelSide in project elk by eclipse.

the class LabelSideSelector method applyLabelSide.

// //////////////////////////////////////////////////////////////////////////////////////
// Helper Methods

            }
        }
    }
}

Example 2 with LabelSide

use of org.eclipse.elk.core.options.LabelSide in project elk by eclipse.

the class LabelSideSelector method basedOnDirection.

/**
 * Configures all labels to be placed according to their edge's direction. If their edge points right, the labels
 * will be placed on the side passed to this method. Otherwise, they will be placed on the opposite side.

                applyLabelSide(edge, side);
            }
        }

Example 3 with LabelSide

use of org.eclipse.elk.core.options.LabelSide in project elk by eclipse.

the class LabelSideSelectorTest method testRemovedNodes.

// ////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Tests
/**
 * All labels on ports and edges have an assigned {@link LabelSide}.

@TestAfterProcessor(LabelSideSelector.class)
