\description{
A \code{ChunkedArray} is a data structure managing a list of
primitive Arrow \link[=Array]{Arrays} logically as one large array. Chunked arrays
may be grouped together in a \link{Table}.
}
\section{Factory}{

The \code{ChunkedArray$create()} factory method instantiates the object from
various Arrays or R vectors. \code{chunked_array()} is an alias for it.
}

\section{Methods}{

\itemize{
\item \verb{$length()}: Size in the number of elements this array contains
\item \verb{$chunk(i)}: Extract an \code{Array} chunk by integer position
\item \verb{$as_vector()}: convert to an R vector
\item \verb{$Slice(offset, length = NULL)}: Construct a zero-copy slice of the array
with the indicated offset and length. If length is \code{NULL}, the slice goes
until the end of the array.
\item \verb{$Take(i)}: return a \code{ChunkedArray} with values at positions given by
integers \code{i}. If \code{i} is an Arrow \code{Array} or \code{ChunkedArray}, it will be
coerced to an R vector before taking.
\item \verb{$Filter(i, keep_na = TRUE)}: return a \code{ChunkedArray} with values at positions where
logical vector or Arrow boolean-type \verb{(Chunked)Array} \code{i} is \code{TRUE}.
\item \verb{$SortIndices(descending = FALSE)}: return an \code{Array} of integer positions that can be
used to rearrange the \code{ChunkedArray} in ascending or descending order
\item \verb{$cast(target_type, safe = TRUE, options = cast_options(safe))}: Alter the
data in the array to change its type.
\item \verb{$null_count()}: The number of null entries in the array
\item \verb{$chunks()}: return a list of \code{Array}s
\item \verb{$num_chunks()}: integer number of chunks in the \code{ChunkedArray}
\item \verb{$type()}: logical type of data
\item \verb{$View(type)}: Construct a zero-copy view of this \code{ChunkedArray} with the
given type.
\item \verb{$Validate()}: Perform any validation checks to determine obvious inconsistencies
within the array's internal data. This can be an expensive check, potentially \code{O(length)}
}
