Class AccessibleRegions

java.lang.Object

software.amazon.jdbc.util.AccessibleRegions

public final class AccessibleRegions
extends java.lang.Object

Helper for parsing the PropertyDefinition.GDB_ACCESSIBLE_REGIONS configuration parameter.

The parameter value is a comma-separated list of AWS region names (e.g. us-east-1,us-west-2). This class normalizes the value into a Set<String> of trimmed, lowercased region names, returning null when the parameter is unset or empty (meaning "no restriction — all regions are accessible").

Centralizing this logic keeps parsing rules consistent across all consumers (failover, read/write splitting, topology monitor, initial connection strategy).
