make_expression_false : a constant "false" node.
make_expression_atom : a relational comparison node (==, <=, !=, etc...) between two ossia::value.
make_expression_pulse : a node that becomes true if a message is received opn a given address since the last time update() has been called on it.
make_expression_not : standard logical not operator.
make_expression_composition : standard logical and, or, xor, operators between two expressions..

See also: expression_atom; expression_bool; expression_composition; expression_not; expression_pulse

OSSIA_EXPORT ossia::unit_t ossia::parse_unit	(	std::string_view	text,
		const ossia::unit_t &	dataspace

parse_unit Takes a text and a dataspace and gives a corresponding unit.

Parameters

text	The text to parse
dataspace	A dataspace such as ossia::color_u, ossia::distance_u...

Returns: Corresponding unit, or the same unit as input if it was not found.

◆ parse_unit() [2/3]

template<typename T >

ossia::unit_t ossia::parse_unit	(	std::string_view	text,
		T	dataspace
	)

parse_unit Alternative if we already have a dataspace type at hand.

Note: T should be a dataspace, such as ossia::color_u.

Todo:: In 2020 enforce this with concepts...

◆ parse_dataspace()

OSSIA_EXPORT ossia::unit_t ossia::parse_dataspace ( std::string_view text )

parse_dataspace

Parameters

text	Something like color, etc.

Returns: A value corresponding to the dataspace, without any specific unit.

◆ get_unit_accessor()

OSSIA_EXPORT char ossia::get_unit_accessor	(	const ossia::unit_t &	,
		uint8_t	n
	)

get_unit_accessor Return the character corresponding to the accessor

e.g. for unit == rgb, n == 1, the function returns 'g'.

Note: Will return 0 (as in "(char)0") if anything is invalid.

◆ make_value()

OSSIA_EXPORT value_with_unit ossia::make_value	(	const ossia::value &	v,
		const ossia::unit_t &	u
	)

Convert ///.

make_value Create a value_with_unit

Parameters

v	A value
u	A unit

Returns: The same value with the unit attached if the types were correct.

◆ make_unit()

OSSIA_EXPORT ossia::unit_t ossia::make_unit	(	uint64_t	dataspace,
		uint64_t	unit
	)

get_unit Create an unit from indexes in the variant

Parameters

dataspace	Identifier in the first variant
unit	std::optional identifier in the second variant

Ex. : position.opengl_u == (1, 4). This is useful for concise serialization / deserialization.

Returns: A corresponding unit

◆ matching_type()

OSSIA_EXPORT ossia::val_type ossia::matching_type ( const ossia::unit_t & u )

underlying_type Get the implementation type of an unit

Parameters

u An unit

Will return Impulse if the unit is invalid.

Returns: The matching type. For instance vec3f for position.cart3D.

◆ convert() [1/4]

OSSIA_EXPORT ossia::value_with_unit ossia::convert	(	const ossia::value_with_unit &	v,
		const ossia::unit_t &	t
	)

convert Convert a value to another unit in the same dataspace

Parameters

v	A value
t	An unit of the same dataspace than the value.

E.g. you can convert 1cm in millimeters, but not 1cm in RGB colors.

Returns: The converted value if both value and unit are valid and convertible, else the input value

◆ to_value()

OSSIA_EXPORT ossia::value ossia::to_value ( const ossia::value_with_unit & v )

convert Convert a value + unit to a simple value

Parameters

v	Value to convert

Returns: Corresponding ossia::value

◆ to_pretty_string()

OSSIA_EXPORT std::string ossia::to_pretty_string ( const ossia::value_with_unit & v )

to_pretty_string Pretty string of unit & value

Returns: For example "[0.2, 1.6, 3.4] rgb"

◆ merge()

OSSIA_EXPORT ossia::value_with_unit ossia::merge	(	const ossia::value_with_unit &	,
		const ossia::value &	,
		ossia::destination_index
	)

merge Merge a computed value in a unit-aware value

The computed value is assumed to be of the same dataspace. For instance if v is a HSV color, then t can also be an HSV color, or just "h", "s", or "v" component, but not a "r" color.

Parameters

The	value with an unit
The	value to merge
std::optional	destination index or bitset to merge with

Returns

◆ convert() [2/4]

OSSIA_EXPORT ossia::value ossia::convert	(	const ossia::value &	v,
		const ossia::unit_t &	source_unit,
		const ossia::unit_t &	destination_unit
	)

convert Convert a value to another unit.

Parameters

v	A value.
source_unit	The unit of v.
destination_unit	The unit in which v shall be converted.

Dataspaces ought to be similar.

Returns: Converted value, else the input value.

◆ parse_unit() [3/3]

template<typename T >

OSSIA_EXPORT ossia::unit_t ossia::parse_unit	(	std::string_view	text,
		T	dataspace
	)

parse_unit Alternative if we already have a dataspace type at hand.

Note: T should be a dataspace, such as ossia::color_u.

Todo:: In 2020 enforce this with concepts...

◆ convert_compatible_domain()

void ossia::convert_compatible_domain	(	domain &	dom,
		ossia::val_type	newtype
	)

inline

Note: check this if the order in domain_base_variant changes.

◆ convert() [3/4]

template<typename T >

T ossia::convert ( const ossia::value & val )

convert Convert a value to the given type.

Parameters

val A value

Returns: The closest possible conversion of the value to T, else a default-constructed T.

◆ get_value_at_index()

OSSIA_EXPORT ossia::value ossia::get_value_at_index	(	const ossia::value &	val,
		const ossia::destination_index &	idx
	)

get_value_at_index

for ossia::list{{1, 2}, 3} and index {}, return {{1, 2}, 3}. for ossia::list{{1, 2}, 3} and index {0}, return {1, 2}. for ossia::list{{1, 2}, 3} and index {0, 0}, return 1. for ossia::list{{1, 2}, 3} and index {0, 1}, return 2. for ossia::list{{1, 2}, 3} and index {0, 2}, return {}. for ossia::list{{1, 2}, 3} and index {1}, return 3. for ossia::list{{1, 2}, 3} and index {1, 0}, return {}. for ossia::list{{1, 2}, 3} and index {2}, return {}.

See also: destination_index

Returns: The value if it is found, else nothing.

◆ value_to_pretty_string()

OSSIA_EXPORT std::string ossia::value_to_pretty_string ( const ossia::value & val )

getValueAsString Returns a string corresponding to the value

Parameters

val	a valid value

Returns: a string in the format : "type: value".

ex. "int: 3" "string: tutu" "list: [ int: 2, float: 3 ]" etc...

◆ convert() [4/4]

template<typename T >

OSSIA_EXPORT T ossia::convert ( const ossia::value & val )

convert Convert a value to the given type.

Parameters

val A value

Returns: The closest possible conversion of the value to T, else a default-constructed T.
