gudusoft.gsqlparser.sqlcmds.SqlCmdsFactory

public class SqlCmdsFactory
extends Object

Factory for creating vendor-specific SQL command resolvers. This factory ensures only the necessary vendor implementations are loaded, reducing memory footprint and class loading overhead. Thread-safe implementation that creates new instances on each request to avoid shared mutable state between concurrent parser instances.

Since:

3.1.0.9
