class xaxis_expression_leaf : public xt::xexpression<xaxis_expression_leaf<CTA>>

An subset of an expression on axis.

The xaxis_expression_leaf class is used with xaxis_function for creating an expression on xnamed_axis, e.g. auto expr = not_equal(axis1, 2) && axis2 < 3. In the example above, axis1, axis2 are xnamed_axis which will be converted to xaxis expression leaves before stored in the xaxis_function object.
