Class DialectRegistry

Object

gudusoft.gsqlparser.pp2.dialect.DialectRegistry

public final class DialectRegistry
extends Object

Maps an EDbVendor to its DialectStrategy. Vendors with a dedicated strategy (Oracle, MSSQL, MySQL, DB2, Snowflake) get it; every other vendor gets a GenericDialect for that vendor. Results are memoised per vendor so forVendor is cheap and the returned strategy is stable.

This is the single place pp2 branches on vendor: the layout rules consult the strategy rather than switching on EDbVendor themselves.

Plan reference: §7.3/S30, §7.4/S30.
