Constructor & Destructor Documentation

geos::noding::OrientedCoordinateArray::OrientedCoordinateArray ( const geom::CoordinateSequence &  p_pts )

inline

Here is the call graph for this function:

Member Function Documentation

static int geos::noding::OrientedCoordinateArray::compareOriented ( const geom::CoordinateSequence &  pts1, bool  orientation1, const geom::CoordinateSequence &  pts2, bool  orientation2  )

staticprivate

int geos::noding::OrientedCoordinateArray::compareTo

(

const OrientedCoordinateArray &

o1

)

const

Compares two OrientedCoordinateArrays for their relative order.

Returns

-1 this one is smaller

0 the two objects are equal

1 this one is greater

In JTS, this is used automatically by ordered lists. In C++, operator< would be used instead....

const

static bool geos::noding::OrientedCoordinateArray::orientation ( const geom::CoordinateSequence &  pts )

staticprivate

Computes the canonical orientation for a coordinate array.

Parameters

pts	the array to test

Returns

true if the points are oriented forwards

false if the points are oriented in reverse
