Field class

Source: R/field.R
Field-class.Rd

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.
