Member Function Documentation

value_type qgar::GenMask1d< double >::coeff (  int  anIdx  )  const [inherited]
 

Get a coefficient value.

Parameters:
anIdx index of the coefficient in the coefficient map

qgar::GenMask1d< double >::GenMask1d (  const GenMask1d< double > &  rhs,
int 
)  [protected, inherited]
 

Disguised copy constructor sharing value array between the passed and the created instance.

This constructor declares an unused int parameter to avoid ambiguous call between it and the copy constructor. It builds a shallow copy of a mask instance.

Parameters:
rhs A mask instance to create a copy from

qgar::GenMask1d< double >::GenMask1d (  unsigned int  aWidth,
const_pointer const   pVals
)  [inherited]
 

Create a mask from an array of values.

The passed array is duplicated using a raw memcopy.

Parameters:
aWidth The width of the array
pVals A pointer to the values.

qgar::GenMask1d< double >::GenMask1d (  unsigned int  aWidth,
value_type  aValue = static_cast<value_type>(0)
)  [inherited]
 

Initialize with given width and value.

Parameters:
aWidth mask width
aValue value to fill the mask with (default 0)
All the coefficients are set to the given value.

qgar::GenMask1d< double >::GenMask1d (  const GenMask1d< U > &  aMask  )  [explicit, inherited]
 

Conversion from another mask.

See also qgar::GenMask1d::operator=, qgar::GenMask1d::shallowCopy.

Warning:
Perform a deep copy: The coefficent map of the source mask is duplicated.

qgar::GenMask1d< double >::GenMask1d (  const GenMask1d< value_type > &  aMask  )  [inherited]
 

Copy constructor.

See also qgar::GenMask1d::operator=, qgar::GenMask1d::deepCopy, and qgar::GenMask1d::shallowCopy.

Warning:
Perform a deep copy: The coefficent map of the source mask is duplicated.

qgar::GenMask1d< double >::GenMask1d (   )  [inherited]
 

Default constructor: Set 0 to mask width, to pointer to the coefficient map, and to reference counter.

Mask1dGaussD2 & qgar::Mask1dGaussD2::operator= (  const Mask1dGaussD2 &  aMask  ) 
 

Assignment.

Parameters:
aMask mask to assign
See also qgar::Mask1dGaussD2(Mask1dGaussD2&), qgar::GenMask1d::deepCopy, and qgar::GenMask1d::shallowCopy.

Warning:
Perform a deep copy: The coefficient map of the source mask is duplicated. Before the copy is performed, the destination mask is not supposed to have the same size as the destination mask.

Definition at line 147 of file Mask1dGaussD2.C.

References qgar::GenMask1d< double >::operator=().

pointer qgar::GenMask1d< double >::pCoeffMap (   )  const [inline, inherited]
 

Get the pointer to the coefficient map.

void qgar::GenMask1d< double >::setCoeff (  int  anIdx,
value_type  aCoeff
)  [inherited]
 

Set coefficient at given index.

Parameters:
anIdx index in the coefficient map
aCoeff coefficient value

GenMask1d<double >* qgar::GenMask1d< double >::shallowCopy (   )  [inherited]
 

Shallow copy: The coefficient map of the source mask is not duplicated.

See also qgar::GenMask1d(Genmask1d<t>&), qgar::GenMask1d::operator=,

Warning:
Before the copy is performed, the destination mask is not supposed to have the same dimensions as the source mask. When the copy is completed, the pixel map of the destination mask is the same memory space as the pixel map of the source mask.

int qgar::GenMask1d< double >::width (   )  const [inline, inherited]
 

Get mask width.
