void VCPattern::CreatePatterns	(	int	width,

	)			[static, private]

Creates the patterns for a given boardsize.

)

[static, private]

Returns the set of PatternSets already constructed.

const VCPatternSet & VCPattern::GetPatterns	(	int	width,
		int	height,
		HexColor	color
	)			[static]

Returns the set of patterns for the given boardsize; creates patterns if they currently do not exist.

Return set of patterns will always be empty if width does not equal height.

Return an empty list for all non-square boards.

Bug:

The "vc-pattern-file" option is not checked here. This means that creating a VCPatternSet for board size (x,y), changing "vc-pattern-file", and then asking for a pattern set for (x,y) will not cause a re-build. No one will want to do this anyway (right?), so it doesn't matter. If you really want to do this, add the filename as part of the key for VCPatternSetMap.
