Detailed Description

Function Documentation

expandEnvelope()

void geos::geom::CoordinateSequence::expandEnvelope

(

Envelope &

env

)

const

Expands the given Envelope to include the coordinates in the sequence.

Parameters

env	the envelope to expand

increasingDirection()

static int geos::geom::CoordinateSequence::increasingDirection ( const CoordinateSequence &  pts )

static

Determines which orientation of the Coordinate array is (overall) increasing.

In other words, determines which end of the array is "smaller" (using the standard ordering on Coordinate). Returns an integer indicating the increasing direction. If the sequence is a palindrome, it is defined to be oriented in a positive direction.

Parameters

pts	the array of Coordinates to test

Returns

1 if the array is smaller at the start or is a palindrome, -1 if smaller at the end

NOTE: this method is found in CoordinateArrays class for JTS

indexOf()

static std::size_t geos::geom::CoordinateSequence::indexOf ( const CoordinateXY *  coordinate, const CoordinateSequence *  cl  )

static

Return position of a Coordinate.
