void DGtal::MLPLengthEstimator< TConstIterator >::init ( const double  h,
const ConstIterator itb,
const ConstIterator ite,
const bool &  isClosed 
)

Initialize the measure computation.

Parameters
hgrid size (must be >0).
itbbegin iterator
iteend iterator
isClosedtrue if the input range is closed.
template<typename TConstIterator>
bool DGtal::MLPLengthEstimator< TConstIterator >::isValid ( ) const

Checks the validity/consistency of the object.

Returns
'true' if the object is valid, 'false' otherwise.
template<typename TConstIterator>
MLPLengthEstimator& DGtal::MLPLengthEstimator< TConstIterator >::operator= ( const MLPLengthEstimator< TConstIterator > &  other)
private

Assignment.

Parameters
otherthe object to copy.
Returns
a reference on 'this'. Forbidden by default.
template<typename TConstIterator>
void DGtal::MLPLengthEstimator< TConstIterator >::selfDisplay ( std::ostream &  out) const

Writes/Displays the object on an output stream.

Parameters
outthe output stream where the object is written.
