}
\arguments{
\item{x}{A NxK \linkS4class{DelayedMatrix}.}
\item{rows, 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]{TRUE}}, missing values
(\code{\link[base]{NA}} or \code{\link[base]{NaN}}) are
omitted from the calculations.}
\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.}
\item{useNames}{If \code{\link{TRUE}} (default), names attributes of result are set. Else if \code{\link{FALSE}}, no naming support is done.}
}
\value{
Returns a \code{\link{logical}} \code{\link{vector}} of length N (K).
}
\description{
Check if all elements in a row (column) of a matrix-like object are equal to
a value.
}
\details{
The S4 methods for \code{x} of type \code{\link{matrix}},
\code{\link{array}}, \code{\link{table}}, or \code{\link{numeric}} call
\code{matrixStats::\link[matrixStats]{rowAlls}} /
\code{matrixStats::\link[matrixStats]{colAlls}}.
}
\examples{
# A DelayedMatrix with a 'matrix' seed
dm_matrix <- DelayedArray(matrix(c(rep(1L, 5),
as.integer((0:4) ^ 2),
seq(-5L, -1L, 1L)),
ncol = 3))
# A DelayedMatrix with a 'SolidRleArraySeed' seed
dm_Rle <- RleArray(Rle(c(rep(1L, 5),
as.integer((0:4) ^ 2),
seq(-5L, -1L, 1L))),
dim = c(5, 3))
colAlls(dm_matrix, value = 1)
colAnys(dm_matrix, value = 2)
rowAlls(dm_Rle, value = 1)
rowAnys(dm_Rle, value = 2)
}

\item \code{matrixStats::\link[matrixStats:rowAlls]{rowAlls}()} and
\code{matrixStats::\link[matrixStats:rowAlls]{colAlls}()} which are
used when the input is a \code{matrix} or \code{numeric} vector.
