#include <triqs/gfs/gf/gf_expr.hpp>

Detailed Description

template<typename L>
struct triqs::gfs::gf_unary_m_expr< L >

Lazy expression node representing the unary minus of a Green's function operand.

Template Parameters

L	Type of the operand (a Green's function or a wrapped scalar).

Definition at line 258 of file gf_expr.hpp.

Public Types
using	L_t = std::remove_reference_t<L>
	Decayed type of the operand.
using	mesh_t = typename L_t::mesh_t
	Mesh type of the expression.
using	regular_t = gf<mesh_t, target_t>
	Regular (owning) type the expression evaluates to.
using	target_t = typename L_t::target_t
	Target type of the expression.

Public Member Functions
