R: FeatherReader class

FeatherReader {arrow} | R Documentation

## FeatherReader class

### Description

This class enables you to interact with Feather files. Create one to connect to a file or other InputStream, and call `Read()` on it to make an `arrow::Table`. See its usage in `read_feather()`.

### Factory

The `FeatherReader$create()` factory method instantiates the object and takes the following arguments:

- `file` an Arrow file connection object inheriting from `RandomAccessFile`.

- `mmap` Logical: whether to memory-map the file (default `TRUE`)

- `...` Additional arguments, currently ignored

### Methods

- `$Read(columns)`: Returns a `Table` of the selected columns, a vector of integer indices

- `$version`: Active binding, returns `1` or `2`, according to the Feather file version
