Field class
Description
field() lets you create an arrow::Field that maps a
DataType to a column name. Fields are contained in
Schemas.
Methods
-
f$ToString(): convert to a string
-
f$Equals(other, check_metadata = FALSE): test for equality.
More naturally called as f == other
-
f$WithMetadata(metadata): returns a new Field with the key-value
metadata set. Note that all list elements in metadata will be coerced
to character.
-
f$RemoveMetadata(): returns a new Field without metadata.
Active bindings
-
$HasMetadata: logical: does this Field have extra metadata?
-
$metadata: returns the key-value metadata as a named list, or NULL
if no metadata is set.
