Detailed Description

Class for storing indices of, e.g., a MatrixLookup.

This class is basically a wrapper around std::vector<size_t>. The major differences are that the class is constant and copying is performed in constant time (shallow copy).

Constructor & Destructor Documentation

theplu::yat::utility::Index::Index ( void  )

Creates an empty Index

theplu::yat::utility::Index::Index ( size_t  n)

Created Index will satisfy a[i] = i.

nsize of created Index
theplu::yat::utility::Index::Index ( const Index a,
const Index b 

Constructed Index c will satisfy c[i]=a[b[i]]

theplu::yat::utility::Index::Index ( const std::vector< size_t > &  vec)


vec is copied
