Public Member Functions  
Range1D ()  
Constructs a range representing the entire range. .  
Range1D (EInvalidRange)  
Constructs an invalid (zero) range.  
Range1D (Index lbound, Index ubound)  
Constructs a range that represents the range [lbound, ubound] .  
bool  full_range () const 
Returns true if the range represents the entire region (constructed from Range1D() ).  
Index  lbound () const 
Return lower bound of the range.  
Index  ubound () const 
Return upper bound of the range.  
Index  size () const 
Return the size of the range (ubound()  lbound() + 1 ).  
bool  in_range (Index i) const 
Return true if the index is in range.  
Range1D &  operator+= (Index incr) 
Increment the range by a constant.  
Range1D &  operator= (Index incr)

Range1D  convert (const Teuchos::Range1D &rng) 
Convert from a 0based Teuchos::Range1D object to a 1based RangePack::Range1D object.  
Teuchos::Range1D  convert (const Range1D &rng) 
Convert from a 1based RangePack::Range1D object to a 0based Teuchos::Range1D object. 
The class Range1D
abstracts a 1D, 1based, range of indexes. It is used to index into vectors and matrices and return subregions of them respectively.
Constructing using Range1D()
yields a range that represents the entire dimension of an object [1, max_ubound]
(an entire vector, all the rows in a matrix, or all the columns in a matrix etc.).
Constructing using Range1D(INVALID)
yields an invalid range [1,0]
with size() == 0
. In fact the condition size() == 0
is the determining flag that a range is not valid. Once constructed with Range1D(INVALID)
, a Range1D
object can pass through many other operations that may change lbound()
and ubound()
but will never change size() == 0
.
Constructing using Range1D(lbound,ubound)
yields a finite dimensional range. The validity of constructed range will only be checked if TEUCHOS_DEBUG
is defined.
There are many nonmember functions that can be used with Range1D
objects.
The default copy constructor and assignment operator functions are allowed since they have the correct semantics.
