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 285 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 184 of file variant_value.cpp.

References callable_.

◆ equals()

bool wfl::variant_callable::equals ( const 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 159 of file variant_value.cpp.

References callable_, and utils::cast_as().

◆ get_callable()

const_formula_callable_ptr wfl::variant_callable::get_callable ( ) const

inline

Definition at line 295 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 119 of file variant_value.cpp.

References callable_, utils::contains(), 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 110 of file variant_value.cpp.

References callable_.

◆ 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 198 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 320 of file variant_value.hpp.
