token Class

Source: R/classes.R, R/tileApply.R
token-class.Rd

Utility class for flagging a piece of data as being ready for processing. This is internal machinery that is mainly useful for forcing S4 dispatch to progress in the expected order and should not be interacted with by end users.

This class and related methods are exported so developers are able to write extending methods for tileApply() where this utility class is used.

Usage

# S4 method for class 'token,missing,missing,missing'
x[i, j, ..., drop = TRUE]

Slots

data

ANY. The wrapped data object.
