#include <triqs/gfs/block/expr.hpp>

Detailed Description

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

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

Template Parameters

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

Definition at line 204 of file expr.hpp.

Public Types
using	L_t = std::decay_t<L>
	Decayed type of the operand.
using	mesh_t = typename L_t::mesh_t
	Mesh type of the expression.
using	target_t = typename L_t::target_t
	Target type of the expression.

Public Member Functions
template<typename LL>
	bgf_unary_m_expr (LL &&l_)
	Construct from the operand.
auto	block_names () const
	Get the block names of the expression.
template<typename... Args>
auto	operator() (Args &&...1) const
	Evaluate the negated expression via call.
template<typename... Keys>
auto	operator[] (Keys &&...keys) const
	Evaluate the negated expression via subscript.
auto	size () const
	Get the number of blocks of the expression.

Public Attributes
L	l
	The operand.

Friends
std::ostream &	operator<< (std::ostream &sout, bgf_unary_m_expr const &expr)
	Stream output of the expression.
