Constructor & Destructor Documentation

TE_DEFINE_VISITABLE 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.

te::da::ST_Relate::ST_Relate	(	const Expression &	g1,
		const Expression &	g2,
		const std::string &	intersectionMatrix = std::string("")
	)

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.
