Detailed Description

template<class t_coder = coder::elias_delta<>, uint32_t t_dens = 128, uint8_t t_width = 0>
class sdsl::enc_vector< t_coder, t_dens, t_width >

A generic immutable space-saving vector class for unsigned integers.

A vector v is stored more space-efficiently by self-delimiting coding the deltas v[i+1]-v[i] (v[-1]:=0). Space of the structure and random access time to it can be controlled by a sampling parameter t_dens.

Template Parameters
t_coderSelf-delimiting coder.
t_densEvery t_dens-th element of v is sampled.
t_widthWidth of the int_vector used to store the samples and pointers. This class is a parameter of csa_sada.
