All Known Subinterfaces:

All Known Implementing Classes:

public interface LabelLayoutConstants

This interface defines constants relevant for the automatic labeling process.

The specifiers PLACE_AT_SOURCE, PLACE_AT_TARGET and PLACE_AT_CENTER express at what approximate location along an edge path a label should be placed by a labeling algorithm.

The specifiers PLACE_ON_EDGE, PLACE_LEFT_OF_EDGE, or PLACE_RIGHT_OF_EDGE express on which side of the edge path a label should be placed by a labeling algorithm.

The specifier PLACE_ANYWHERE expresses that the label can be placed anywhere along the edge or on any side of the edge.

ORed combinations of edge label layout constants like (PLACE_AT_SOURCE | PLACE_RIGHT_OF_EDGE) can be used as preferred placement hints.
