MatchAll

A class that creates the indicator in SQL form which evaluates whether all of the target columns match the specified definition codes, ensuring that the indicator is TRUE only if every target column has a match.

  rule_engine,
  indicator_name,
  target_columns,
  definition_codes,
  regex_prefix_search = FALSE
)

Arguments

rule_engine

Object of class RuleEngine.The rule engine containing the dataset where indicators will be applied.

indicator_name
