Constructors

Modifier	Constructor and Description
	GdbReadWriteSplittingPlugin(PluginService pluginService, java.util.Properties properties)
protected	GdbReadWriteSplittingPlugin(PluginService pluginService, java.util.Properties properties, RwSplitHelpers helpers) Constructor for subclasses that supply their own helper assembly.

Method Summary

Modifier and Type	Method and Description
protected static RwSplitHelpers	gdb(java.util.Properties props) Builds the Global Database assembly (region rules + GWF) with setReadOnly routing.
protected static RwSplitHelpers	gdbHelpers(java.util.Properties props, RoutingSignal routingSignal, SwitchGate switchGate) Shared Global Database assembly builder, parameterized by routing signal and switch gate so the SQL-routed variant can reuse it.
