int function ( Object arg0 ) { HalfEdge loc0 = ( HalfEdge ) arg0 ; int loc1 = compareAngularDirection ( loc0 ) ; return loc1 ; }
compares edges which originate at the same vertex based on the angle they make at their origin vertex with the positive x-axis . this allows sorting edges around their origin vertex in ccw order . concode_field_sep HalfEdge next concode_elem_sep Coordinate orig concode_elem_sep HalfEdge sym concode_field_sep HalfEdge next concode_elem_sep HalfEdge init concode_elem_sep void init concode_elem_sep HalfEdge oNext concode_elem_sep HalfEdge sym concode_elem_sep double deltaX concode_elem_sep void setSym concode_elem_sep HalfEdge prev concode_elem_sep double deltaY concode_elem_sep int degree concode_elem_sep void insert concode_elem_sep Coordinate dest concode_elem_sep void insertAfter concode_elem_sep HalfEdge prevNode concode_elem_sep int compareAngularDirection concode_elem_sep Coordinate orig concode_elem_sep HalfEdge find concode_elem_sep boolean equals concode_elem_sep void setNext concode_elem_sep HalfEdge create concode_elem_sep String toString
