Implements Kratos::Expression.

◆ GetMaxDepth()

template<class TOperationType >
std::size_t Kratos::UnaryStatisticsExpression< TOperationType >::GetMaxDepth ( ) const

Get the Max Depth of the lazy expression tree.

Returns the maximum depth of the lazy expression tree.

Warning
This is a recursive computation, hence this should not be done repeatedly unless necessary.
Returns
IndexType Max depth of the lazy expression tree.

Implements Kratos::Expression.
