Enum TargetRole

java.lang.Object

java.lang.Enum<TargetRole>

software.amazon.jdbc.plugin.readwritesplitting.signal.TargetRole

All Implemented Interfaces:

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

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

The connection role a RoutingSignal resolves for a given JDBC call in the unified read/write splitting plugin.

• WRITER — the call should run on the writer connection.
• READER — the call should run on a reader connection.
• KEEP — pin to the current connection (explicit /*@keep* / hint).
• NO_DECISION — this method is not a routing trigger for this signal; the signal abstains and no switch is attempted (distinct from KEEP, which actively pins).

Method Detail

values

public static TargetRole[] 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 (TargetRole c : TargetRole.values())
    System.out.println(c);

Returns:

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

valueOf

public static TargetRole 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
