charport_class_of: Registered ALTREP class serving a character vector

In charport: ALTREP String Interoperability

Registered ALTREP class serving a character vector

Description

Identifies whether a registered ALTREP class claims 'x'. This is a class-membership question answered without touching the vector's data: it never materializes 'x' and reports a match even when the class reader would decline to serve this particular instance (for example, a materialized 'charvec').

Usage

charport_class_of(x)

Arguments

x	a character vector.

Value

'"package::class"' for a registered class match when class metadata is available; otherwise 'NA_character_'.

Examples

charport_class_of(charvec("a"))
charport_class_of(letters)
