Enum RoutingHint

java.lang.Object

java.lang.Enum<RoutingHint>

software.amazon.jdbc.parser.RoutingHint

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RoutingHint>

public enum RoutingHint
extends java.lang.Enum<RoutingHint>

Explicit routing hint parsed from a SQL comment (e.g. /*@reader* /, /*@writer* /, or /*@keep* /). Used to override the query-type-based routing decision: READER and WRITER force a specific connection role, while KEEP suppresses re-routing and runs the statement on the current connection.

Method Detail

values

public static RoutingHint[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RoutingHint c : RoutingHint.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RoutingHint valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromString

public static @Nullable RoutingHint fromString(@Nullable java.lang.String value)

Parses a routing hint keyword into the corresponding enum value.

Parameters:

value - the hint keyword (case-insensitive), e.g. "reader", "writer", or "keep"

Returns:

the matching RoutingHint, or null if the value is null or unrecognized
