Method Detail

values

public static GeometryParsers[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GeometryParsers c : GeometryParsers.values())
    System.out.println(c);

Returns:

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

valueOf

public static GeometryParsers valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

parsePath

public Path parsePath(CharSequence s)

Parses a path.

 [ ( x1 , y1 ) , ... , ( xn , yn ) ]

 ( x1 , y1   , ... ,   xn , yn )
  x1 , y1   , ... ,   xn , yn
 

Parameters:

s - The path to parse.

Returns:

A Path.

parsePolygon

public double[][] parsePolygon(CharSequence s)

Parses a polygon.

 ( x1 , y1 ) , ... , ( xn , yn )
 ( x1 , y1   , ... ,   xn , yn )
  x1 , y1   , ... ,   xn , yn
 

Parameters:

s - The polygon to parse.

Returns:

A list of points.

parseCircle

public double[] parseCircle(CharSequence s)

Parses a circle.

 < ( x , y ) , r >
 ( ( x , y ) , r )
 ( x , y ) , r
 x , y   , r
 

Parameters:

s - The circle to parse.

Returns:

[p.x, p.y, r]: A 3 elements array where the first 2 doubles represents a center point and the last element the radius.

parsePoint

public double[] parsePoint(CharSequence s)

Parses a point.
