Method Detail

x

public final Hull x(DatumFunction<Double> xAccessor)

Sets the x-coordinate accessor.

The default accessor consider datum as a two element array and returns the first element.

Parameters:

xAccessor - the x accessor

Returns:

the current hull

y

public final Hull y(DatumFunction<Double> yAccessor)

Sets the y-coordinate accessor.

The default accessor consider datum as a two element array and returns the first element.

Parameters:

yAccessor - the y accessor

Returns:

the current hull

apply

public final <T> Array<T> apply(Array<T> vertices)

Returns the convex hull for the specified vertices array, using the current x- and y-coordinate accessors.

The returned convex hull is represented as an array containing a subset of the input vertices, arranged in counterclockwise order (for consistency with polygon.clip).

Parameters:

vertices - the array of vertices

Returns:

the convex hull as an array of vertices

apply

public final <T> List<T> apply(List<T> vertices)

Returns the convex hull for the specified vertices array, using the current x- and y-coordinate accessors.

The returned convex hull is represented as an array containing a subset of the input vertices, arranged in counterclockwise order (for consistency with polygon.clip).

Parameters:

vertices - the array of vertices

Returns:

the convex hull as an array of vertices
