\description{
This set of S3 classes describe the action of dplyr verbs. These are
currently used for SQL sources to separate the description of operations
in R from their computation in SQL. This API is very new so is likely
to evolve in the future.
}
\details{
\code{op_vars()} and \code{op_grps()} compute the variables and groups from
a sequence of lazy operations. \code{op_sort()} and \code{op_frame()} tracks the
order and frame for use in window functions.
