Interface between bru_input and bru_mapper

Source: R/bru_input.R
ibm_input.Rd

Associate bru_input objects with bru_mapper objects.

Usage

ibm_input_set(mapper, input)

ibm_input_new(mapper, ...)

ibm_input_available(mapper)

ibm_input_get(mapper)

bm_autodetect()

Arguments

mapper

A bru_mapper object.

input

A bru_input object, or NULL to remove any existing input. Alternatively, an existing bru_mapper object with or without associated input can be provided, in which case the input from that mapper is copied.

...

Passed on to new_bru_input().

Functions

  • ibm_input_set(): Add an existing bru_input to a bru_mapper.

  • ibm_input_new(): Create and add a bru_input to a bru_mapper.

  • ibm_input_available(): Check if a bru_input is associated with a bru_mapper.

  • ibm_input_get(): Get the bru_input associated with a bru_mapper.

  • bm_autodetect(): Create a bru_mapper placeholder object of class bm_autodetect. The main purpose of this class is to attach bru_input information to it, which is later used to determine a suitable 'real' mapper type.
