Method Details

parse

static Canvas.PopulatorContext.ViewStrategy parse(String[] rows)

Parses an array of strings to create a Canvas.PopulatorContext.ViewStrategy for rendering elements on a canvas.

The provided array of strings represents a grid, where each character in the strings indicates the presence or absence of an element at a specific grid position. Use 'x' to indicate the presence of an element and 'o' to indicate the absence of an element.

Example:

              "ooooxoooo"
         };
         
         ViewStrategy viewStrategy = ViewStrategy.parse(rows);
         canvas.viewStrategy(viewStrategy);
