ExpressionFunction

com.phasmidsoftware.number.expression.expr.ExpressionFunction
See theExpressionFunction companion object
sealed trait ExpressionFunction[P] extends P => Valuable

Represents a named, generic computation or transformation from an input of type P to an output value of type Valuable. The ExpressionFunction trait defines an abstract function by extending the (P => Valuable) function type. It can be used to model mathematical or computational expressions with a specific name. It is the super-type of ExpressionMonoFunction and ExpressionBiFunction.

def applyExact(p: P): Option[Eager]

Applies the function exactly to the given input of type P, returning an Option of type Valuable if the application is successful.

Applies the function exactly to the given input of type P, returning an Option of type Valuable if the application is successful.

If defined, the output is guaranteed to be exact.

Value parameters

p

the input parameter of type P to which the function is applied

Attributes

Returns

an Option containing a Valuable result if the function executes successfully, or None if the operation cannot produce a valid result

def name: String

Returns the name of the expression function.

Returns the name of the expression function.

Attributes

Returns

a string representing the name of the function
