Detailed Description

The MathSolverController allows to configure and run math operations on an editor.

Note: following limitation applies: the part managed by the associated editor must be a "Raw Content" and the specified blocks must be of type "Math".

See also: Editor.; OffscreenEditor.

Since: 4.0

Note: following limitation applies: incompatible with Offscreen interactivity service.

Parameters

blockId	the identifier of the block.
action	the action used by the math solver.
overrideConfiguration	the extra configuration used.

Exceptions

std::invalid_argument	when `blockId` is invalid.
std::invalid_argument	when `action` is invalid.
std::invalid_argument	when `overrideConfiguration` is invalid.
std::runtime_error	when associated part type is not "Raw Content" or block type is not "Math".

	)

blockId	the identifier of the block.
task	the task to diagnose: either `"numerical-computation"` or `"evaluation"`.
overrideConfiguration	the extra configuration used.

Returns: a diagnostic code.

Since: 4.1

◆ getEvaluables()

virtual std::vector<MathEvaluationVariables> myscript::iink::MathSolverController::getEvaluables ( const String & blockId )

pure virtual

Returns the list of variable names that can be evaluated in the specified block. A block with no syntax error can be evaluated when it contains:

a variable definition
a single (multi-occurrence) undefined variable and no equal sign
an equal sign and two undefined variables, with at least one being a single-occurrence Returns an empty list if block cannot be evaluated.

Example: a math block containing "y = x^3 + 2x + 1" can evaluate: { in:"x", out:"y" } a math block containing "2 * y = x - 1" can evaluate: {{ in:"x", out:"y" }, { in:"y", out:"x" }} a math block containing "y = 3 * 4" can evaluate: { in:"", out:"y" } a math block containing "sin(x) + x/2" can evaluate: { in:"x", out:"" }

Note: in case both variables can be evaluated interchangeably, the first returned MathEvaluationVariables will use the (leftmost) isolated variable as output if any. Example: "y = cos(x) + 1" will always return: {{ in:"x", out:"y" }, { in:"y", out:"x" }} in that order.

Parameters

blockId the identifier of the block.

Returns: a list of MathEvaluationVariables that can be evaluated.

Exceptions

std::invalid_argument	when `blockId` is invalid.
std::runtime_error	when associated part type is not "Raw Content" or block type is not "Math".

Since: 4.1

◆ evaluate()

virtual std::vector<std::vector<graphics::PointD> > myscript::iink::MathSolverController::evaluate	(	const String &	blockId,
		const MathEvaluationVariables &	variables,
		double	from,
		double	to,
		int	pointCount,
		std::shared_ptr< ParameterSet >	overrideConfiguration = `nullptr`
	)

pure virtual

Returns the list of points resulting from evaluating the given variables in the specified block.

Example: for "y = 2x", evaluate(blockId, { in:"x", out:"y" }, -1, 1, 3) returns { {-1, -2}, {0, 0}, {1, 2} }

Parameters

blockId	the identifier of the block.
variables	the variables to evaluate.
from	the start of the range to evaluate.
to	the end of the range to evaluate.
pointCount	the number of values to evaluate between [from, to].

Exceptions

std::invalid_argument	when `blockId` is invalid.
std::invalid_argument	when `variables` are not evaluables.
std::invalid_argument	when `from` or `to` is not a number.
std::invalid_argument	when `from` is greater than `to`.
std::invalid_argument	when `pointCount` is not in `[1, 10000]`.
std::invalid_argument	when `overrideConfiguration` is invalid.
std::runtime_error	when associated part type is not "Raw Content" or block type is not "Math".

◆ asVariableDefinition()

virtual MathVariableDefinition myscript::iink::MathSolverController::asVariableDefinition ( const String & blockId )

pure virtual

Parameters

blockId the identifier of the block.

Returns: the name and value of the defined variable if any, otherwise an object which valid() method returns false.

	)

pure virtual

Returns the value associated with the given variable name for the specified block.

		const String &	name,
		double	value
	)

pure virtual

Sets the value associated with the given variable name for the specified block.

Parameters

blockId	the identifier of the block.
name	the variable name.
value	the variable value.

◆ removeVariableValue()

virtual bool myscript::iink::MathSolverController::removeVariableValue	(	const String &	blockId,
		const String &	name
	)

pure virtual

Removes the definition of the given variable name for the specified block.

Parameters

blockId	the identifier of the block.
