NAME
Games::Nonogram::Clue
DESCRIPTION
This is used internally to handle clues in a row or in a column.
METHODS
new
creates an object.
set
sets an array of the length of clues in a row/column.
reset_blocks
initializes the positions of clues. Actually this may fix them when there're no free cells, as this tries to put blocks so as not to cross each other.
as_string
returns a stringified form of the line for the clues.
dump_blocks
similar to above but returns more detailed information of the blocks of the clues.
is_done
returns if each block in the line is fixed or not.
die_if_invalid
dies if any of the blocks in the line can not have enough spaces (while brute-forcing, or when the puzzle is broken).
on
tells each block in the line that the given id (cell) should belong to one of the blocks.
off
tells each block in the line that the given id (cell) should not belong to one of the blocks.
value
returns if the given id (cell) belongs to a block or not.
might_have
returns if the given id (cell) can belong to a block or not.
update
sees through the line and turns on/off the cells it can surely tell.
candidates
returns all the possible patterns of the line.
ACCESSORS
id
returns a clue id.
blocks
returns all the blocks in the clues.
size
returns how many cells are there in a row/column for the clues.
line
returns a row/column for the clues.
block
returns a block of the given (block) id.
