Constructor & Destructor Documentation

te::da::ST_Relate::ST_Relate	(	Expression *	g1,
		Expression *	g2,
		LiteralString *	intersectionMatrix = `0`
	)

Constructor.

Parameters

g1	The first geometric argument.
g2	The second geometric argument.
intersectionMatrix	A intersection matrix.

Note: The third parameter is optional. If omitted the function result is a intersection matrix otherwise the result is a boolean.; The operator will take the ownership of the given arguments.

Constructor.

Parameters

g1	The first geometric argument.
g2	The second geometric argument.
intersectionMatrix	A intersection matrix.
