Detailed Description

A helper class for the $\Psi$ and LF function for (compressed) suffix arrays that are based on the compressed $\Psi$ function.

Member Function Documentation

template<class CsaPsi>

const_iterator sdsl::psi_of_csa_psi< CsaPsi >::begin ( ) const [inline]

Returns a const_iterator to the first element.

Required for the STL Container Concept.

template<class CsaPsi>

const_iterator sdsl::psi_of_csa_psi< CsaPsi >::end ( ) const [inline]

Returns a const_iterator to the element after the last element.

Required for the STL Container Concept.

template<class CsaPsi>

value_type sdsl::psi_of_csa_psi< CsaPsi >::operator() ( size_type i ) const [inline]

Calculate the LF mapping at position i.

The LF mapping function is the inverse to the $\Psi$ function. That is $LF[\Psi(i)]=i$ .

Parameters:

i	The index for which the LF value should be calculated, $i\in [0..size()-1]$ .

template<class CsaPsi>

value_type sdsl::psi_of_csa_psi< CsaPsi >::operator[] ( size_type i ) const [inline]

Calculate the $\Psi$ value at position i.

   \param i The index for which the \form#6 value should be calculated, \form#105.
   \par Time complexity

$\Order{1}$ , if the enc_vector_type of the csa returns the entry in constant time.
