\arguments{
\item{x}{A NxK \linkS4class{DelayedMatrix}.}

\item{rows}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{cols}{A \code{\link{vector}} indicating the subset of rows
(and/or columns) to operate over. If \code{\link{NULL}}, no subsetting is
done.}

\item{value}{The value to search for.}

\item{na.rm}{If \code{\link[base:logical]{TRUE}}, \code{\link{NA}}s
are excluded first, otherwise not.}

\item{force_block_processing}{\code{FALSE} (the default) means that a
seed-aware, optimised method is used (if available). This can be overridden
to use the general block-processing strategy by setting this to \code{TRUE}
(typically not advised). The block-processing strategy loads one or more
(depending on \verb{\link[DelayedArray]\{getAutoBlockSize\}()}) columns (\code{colFoo()})
or rows (\code{rowFoo()}) into memory as an ordinary \link[base:array]{base::array}.}

\item{...}{Additional arguments passed to specific methods.}
}
\value{
Returns a \code{\link{logical}} \code{\link{vector}} of length N (K).

Check if all elements in a row (column) of a matrix-like object are equal to
a value.
