Parameters:

r - The input buffer.

len - The number of chars of the input buffer.

Returns:

The TinyRect object or null.

parsePoint

public TinyPoint parsePoint(char[] r,
                            int len)

parseDashArray

public int[] parseDashArray(char[] r,
                            int len)

Parses dasharray of fixed point numbers from a list of comma-separated (with optional white space) lengths of alternating dashes and gaps. For example, "5,3,2,5,3,2".

Parameters:

len - The number of chars of the input buffer.

Returns:

The dasharray or null.

parseNumbers

public TinyVector parseNumbers(char[] r,
                               int len)

Parses the list of numbers. Parses a semicolon-separated list of number values

parseSpline

public TinyPath parseSpline(char[] r,

Parses the spline path. Parses a set of Bézier control points, defining a cubic Bézier function that controls interval pacing. The input buffer value is a semicolon separated list of control point descriptions. Each control point description is a set of four values: x1 y1 x2 y2, describing the Bézier control points for one segment.
