instance()

value_t ultra::str::literal::instance ( ) const

inlinenodiscardfinalvirtual

Produce the runtime value of the terminal.

Returns

the value associated with this terminal

This function returns the value represented by the terminal when the program is evaluated. The returned value may depend on the evaluation context (e.g. the current input vector), but does not depend on any child expressions.

Note

Implementations must not throw exceptions and should be side-effect free to preserve referential transparency during program evaluation.

Implements ultra::terminal.
