Method Contains

factstore/factstore.go:38–38

Contains returns true if given atom is already present in store. This is a convenience method that has a straightforward implementation in terms of GetFacts. It does not return error and treats any error condition as "false". Clients who distinguish "absent" from "error" should call GetFacts directl

(ast.Atom)

	// error condition as "false". Clients who distinguish "absent" from "error"
	// should call GetFacts directly.
	Contains(ast.Atom) bool

	// ListPredicates lists predicates available in this store.
