Enum Constant Summary

Enum Constants

Enum Constant	Description
BestAreaFit	Packs rectangles such that the wasted/empty area within the bin is minimised.
TopRightCornerDistance	Packs rectangles such that the distance between the top-right corner of each rectangle and that of the bin is maximised.
TouchingPerimeter	Packs rectangles such that the total touching perimeter length is maximised.

Method Summary

Modifier and Type	Method	Description
static PGS_Optimisation.RectPackHeuristic	valueOf(String name)	Returns the enum constant of this class with the specified name.

Enum Constant Details

BestAreaFit

public static final PGS_Optimisation.RectPackHeuristic BestAreaFit

Packs rectangles such that the wasted/empty area within the bin is minimised. This heuristic tends to generate packings that are less dense but are better at covering the whole area (particularly if there is much spare area) than the other heuristics.

TouchingPerimeter

public static final PGS_Optimisation.RectPackHeuristic TouchingPerimeter

Packs rectangles such that the total touching perimeter length is maximised. In practice, rectangles are packed against the left-most and upper-most boundary of the bin first.

TopRightCornerDistance

public static final PGS_Optimisation.RectPackHeuristic TopRightCornerDistance

Packs rectangles such that the distance between the top-right corner of each rectangle and that of the bin is maximised.

Method Details

values

public static PGS_Optimisation.RectPackHeuristic[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static PGS_Optimisation.RectPackHeuristic valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
