Named comparison functions
Note that these return CoordinateExpr, not bool. Unlike most arithmetic and assignment operators, scalar interoperability is provided for comparisons; expressions like * if (all(extent.gt(0))) ... * are both ubiquitous and easy to interpret.
CoordinateExpr< N >	eq (Extent< T, N > const &other) const
CoordinateExpr< N >	ne (Extent< T, N > const &other) const
CoordinateExpr< N >	lt (Extent< T, N > const &other) const
CoordinateExpr< N >	le (Extent< T, N > const &other) const
CoordinateExpr< N >	gt (Extent< T, N > const &other) const
CoordinateExpr< N >	ge (Extent< T, N > const &other) const
CoordinateExpr< N >	eq (T scalar) const

CoordinateExpr< N >	lt (T scalar) const
CoordinateExpr< N >	le (T scalar) const
CoordinateExpr< N >	gt (T scalar) const
CoordinateExpr< N >	ge (T scalar) const
Additive arithmetic operators
No scalar interoperability is provided for Extent additive arithmetic operations.
Point< T, N >	operator+ (Point< T, N > const &other) const
Extent< T, N >	operator+ (Extent< T, N > const &other) const
Extent< T, N >	operator- (Extent< T, N > const &other) const
Extent< T, N > &	operator+= (Extent< T, N > const &other)
Extent< T, N > &	operator-= (Extent< T, N > const &other)
Extent< T, N >	operator+ () const
Extent< T, N >	operator- () const
Multiplicative arithmetic operators
As usual with matrices and vectors, Extent can be multiplied or divided by a scalar.
Extent< T, N >	operator* (T scalar) const
Extent< T, N > &	operator*= (T scalar)
Extent< T, N >	operator/ (T scalar) const
Extent< T, N > &	operator/= (T scalar)
Public Member Functions inherited from lsst.afw.geom::CoordinateBase< Extent< T, N >, T, N >
T &	operator[] (int n)
T const &	operator[] (int n) const
T &	coeffRef (int n)
T const &	coeffRef (int n) const
EigenVector const &	asEigen () const
	Return a fixed-size Eigen representation of the coordinate object. More...

Protected Member Functions
	ExtentBase (T val=static_cast< T >(0))
	Construct an Extent<T,N> with all elements set to the same scalar value. More...
template<typename Vector >
	ExtentBase (Eigen::MatrixBase< Vector > const &vector)

Protected Member Functions inherited from lsst.afw.geom::CoordinateBase< Extent< T, N >, T, N >
