Method Details

parse

public static byte[][] parse(GameSchema gameSchema,
 String... rows)

Parses a string based field descriptor.
Example usage:
byte data[][] =
QuadraticArrays.parse(
"100000000",
"020100000",
"000320100",
"010000456",
"000010000",
"000000010",
"001000000",
"000001000",
"000000001"
);
GameMatrix matrix = ...
matrix.setAll(data);


Parameters:

gameSchema - the game schema that defines the input data dimensions.

rows - array of strings with each string describing a row. Digits get converted to the element values, everything else gets converted to UNSET. Example for one row: "126453780".

Returns:

the parsed array.

Throws:

IllegalArgumentException - if one of the rows has a wrong size.
