Database

Sets the passphrase used to crypt and decrypt an SQLCipher database.

Call this method from Configuration.prepareDatabase, as in the example below:

var config = Configuration()
config.prepareDatabase { db in
    try db.usePassphrase("secret")
}

Changes the passphrase used by an SQLCipher encrypted database.

Deletes the synchronization triggers for a synchronized FTS5 table

Add a custom FTS5 tokenizer.

class MyTokenizer : FTS5CustomTokenizer { ... }
db.add(tokenizer: MyTokenizer.self)

Creates a pattern from a raw pattern string; throws DatabaseError on invalid syntax.

The pattern syntax is documented at https://www.sqlite.org/fts5.html#full_text_query_syntax

try db.makeFTS5Pattern(rawPattern: "and", forTable: "document") // OK
try db.makeFTS5Pattern(rawPattern: "AND", forTable: "document") // malformed MATCH expression: [AND]

Creates an FTS5 tokenizer, given its descriptor.

let unicode61 = try db.makeTokenizer(.unicode61())

It is a programmer error to use the tokenizer outside of a protected database queue, or after the database has been closed.

Use this method when you implement a custom wrapper tokenizer:

final class MyTokenizer : FTS5WrapperTokenizer {
    var wrappedTokenizer: FTS5Tokenizer

    init(db: Database, arguments: [String]) throws {
        wrappedTokenizer = try db.makeTokenizer(.unicode61())
    }
}
