Member Function Documentation

◆ as_bool()

virtual bool wfl::variant_callable::as_bool ( ) const

inlineoverridevirtual

Returns a bool expression of the variant value.

Reimplemented from wfl::variant_value_base.

Definition at line 305 of file variant_value.hpp.

References callable_.

◆ deref_iterator()

variant wfl::variant_callable::deref_iterator ( const utils::any & iter ) const

overridevirtual

Implements the dereference functionality of variant_iterator for a value of this type.

Parameters

iter	The opaque reference that was passed to the variant_iterator by make_iterator.

Reimplemented from wfl::variant_value_base.

Definition at line 169 of file variant_value.cpp.

References callable_.

◆ equals()

bool wfl::variant_callable::equals ( variant_value_base & ) const

overridevirtual

Called to determine if this variant is equal to another of the same type.

This function is only called if get_type() returns the same result for both arguments.

Reimplemented from wfl::variant_value_base.

Definition at line 144 of file variant_value.cpp.

References callable_.

◆ get_callable()

const_formula_callable_ptr wfl::variant_callable::get_callable ( ) const

inline

Definition at line 315 of file variant_value.hpp.

References callable_.

◆ get_debug_string()

std::string wfl::variant_callable::get_debug_string	(	formula_seen_stack &	,
		bool
	)		const

overridevirtual

Returns debug info for the variant value.

Reimplemented from wfl::variant_value_base.

Definition at line 104 of file variant_value.cpp.

References callable_, wfl::read_write, and wfl::write_only.

◆ get_serialized_string()

std::string wfl::variant_callable::get_serialized_string ( ) const

overridevirtual

Returns the stored variant value in formula syntax.

Reimplemented from wfl::variant_value_base.

Definition at line 93 of file variant_value.cpp.

References callable_.

◆ get_type()

virtual const formula_variant::type& wfl::variant_callable::get_type ( ) const

inlineoverridevirtual

Returns the id of the variant type.

Reimplemented from wfl::variant_value_base.

Definition at line 332 of file variant_value.hpp.

◆ iterator_dec()

void wfl::variant_callable::iterator_dec ( utils::any & ) const

overridevirtual

Implements the decrement functionality of variant_iterator for a value of this type.

The parameter is an opaque reference that was passed to the variant_iterator by make_iterator.

Reimplemented from wfl::variant_value_base.

Definition at line 183 of file variant_value.cpp.

◆ iterator_equals()

virtual bool wfl::variant_callable::iterator_equals	(	const utils::any &	,
		const utils::any &
	)		const

inlineoverridevirtual

Implements the equality functionality of variant_iterator for a value of this type.

Note that this is only called if the two iterators are already known to be of the same type.

The first parameter is an opaque reference that was passed to the variant_iterator by make_iterator. The second parameter is an opaque reference that was passed to the variant_iterator by make_iterator.

Reimplemented from wfl::variant_value_base.

Definition at line 343 of file variant_value.hpp.

◆ iterator_inc()

void wfl::variant_callable::iterator_inc ( utils::any & ) const

overridevirtual

Implements the increment functionality of variant_iterator for a value of this type.

The parameter is an opaque reference that was passed to the variant_iterator by make_iterator.

Reimplemented from wfl::variant_value_base.

Definition at line 178 of file variant_value.cpp.

◆ less_than()

bool wfl::variant_callable::less_than ( variant_value_base & ) const

overridevirtual

Called to determine if this variant is less than another of the same type.

This function is only called if get_type() returns the same result for both arguments.

Reimplemented from wfl::variant_value_base.

Definition at line 150 of file variant_value.cpp.

References callable_.

◆ make_iterator()

boost::iterator_range< variant_iterator > wfl::variant_callable::make_iterator ( ) const

overridevirtual

Creates an iterator pair that can be used for iteration.

For an iterable type, it should use the two-argument constructor of variant-iterator, passing the underlying iterator as the utils::any parameter.

This creates both the begin and end iterator, but the variant implementation discards one of the two.

Reimplemented from wfl::variant_value_base.

Definition at line 156 of file variant_value.cpp.

References callable_, inputs, and wfl::variant_value_base::make_iterator().

◆ notify_dead()

void wfl::variant_callable::notify_dead ( )

inlineoverrideprivatevirtual

Reimplemented from wfl::callable_die_subscriber.

Definition at line 349 of file variant_value.hpp.

References callable_.

◆ num_elements()

virtual std::size_t wfl::variant_callable::num_elements ( ) const

inlineoverridevirtual

Returns the number of elements in a type.

Not relevant for every derivative.

Reimplemented from wfl::variant_value_base.

Definition at line 310 of file variant_value.hpp.

◆ string_cast()

virtual std::string wfl::variant_callable::string_cast ( ) const

inlineoverridevirtual

Returns the stored variant value in plain string form.

Reimplemented from wfl::variant_value_base.

Definition at line 320 of file variant_value.hpp.
