Member Typedef Documentation

Compare_x_2

typedef unspecified_type LargestEmptyIsoRectangleTraits_2::Compare_x_2

Predicate object.

Must provide the operator Comparison_result operator()(Point_2 p, Point_2 q) which returns SMALLER, EQUAL or LARGER according ding to the \( x\)-ordering of points p and q.

Compare_y_2

typedef unspecified_type LargestEmptyIsoRectangleTraits_2::Compare_y_2

Predicate object.

Must provide the operator Comparison_result operator()(Point_2 p, Point_2 q) which returns SMALLER, EQUAL or LARGER according to the \( y\)-ordering of points p and q.

Less_x_2

typedef unspecified_type LargestEmptyIsoRectangleTraits_2::Less_x_2

Predicate object.

Must provide the operator bool operator()(Point_2 p, Point_2 q) which returns whether p is less than q according to their \( x\)-ordering.

Less_y_2

typedef unspecified_type LargestEmptyIsoRectangleTraits_2::Less_y_2

Predicate object.

Must provide the operator bool operator()(Point_2 p, Point_2 q) which returns whether p is less than q according to their \( y\)-ordering.
