discard_block_engine

function template
<random>

std::relational operators

equality (1)
template <class Engine, size_t p, size_t r>bool operator== ( const discard_block_engine<Engine,p,r>& lhs,                  const discard_block_engine<Engine,p,r>& rhs );
inequality (2)
template <class Engine, size_t p, size_t r>bool operator!= ( const discard_block_engine<Engine,p,r>& lhs,                  const discard_block_engine<Engine,p,r>& rhs );
Relational operators
Performs the appropriate equality or inequality comparison operation between the discard_block_engine objects lhs and rhs.

Two engines of the same type compare equal if they have both the same internal state, and hence any number of future calls to the operator() member on both objects would generate the same sequence of values.

Parameters

lhs, rhs
discard_block_engine objects of the same type (to the left- and right-hand side of the operator, respectively).

Return Value

true if they compare equal, and false otherwise.

Complexity

Linear on the state size.
