Enum RequestOptions.Priority

  • All Implemented Interfaces:
    com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, Serializable, Comparable<RequestOptions.Priority>
    Enclosing class:
    RequestOptions
    public static enum RequestOptions.Priority
extends Enum<RequestOptions.Priority>
implements com.google.protobuf.ProtocolMessageEnum
     The relative priority for requests. Note that priority is not applicable
 for [BeginTransaction][google.spanner.v1.Spanner.BeginTransaction].

 The priority acts as a hint to the Cloud Spanner scheduler and does not
 guarantee priority or order of execution. For example:

 * Some parts of a write operation always execute at `PRIORITY_HIGH`,
   regardless of the specified priority. This may cause you to see an
   increase in high priority workload even when executing a low priority
   request. This can also potentially cause a priority inversion where a
   lower priority request will be fulfilled ahead of a higher priority
   request.
 * If a transaction contains multiple operations with different priorities,
   Cloud Spanner does not guarantee to process the higher priority
   operations first. There may be other constraints to satisfy, such as
   order of operations.

    • Method Detail

      • values

        public static RequestOptions.Priority[] 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 (RequestOptions.Priority c : RequestOptions.Priority.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static RequestOptions.Priority valueOf​(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:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • getNumber

        public final int getNumber()
        Specified by:
        getNumber in interface com.google.protobuf.Internal.EnumLite
        Specified by:
        getNumber in interface com.google.protobuf.ProtocolMessageEnum

      • valueOf

        @Deprecated
public static RequestOptions.Priority valueOf​(int value)
        Deprecated.
        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:
        value - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • forNumber

        public static RequestOptions.Priority forNumber​(int value)
        Parameters:
        value - The numeric wire value of the corresponding enum entry.
        Returns:
        The enum associated with the given numeric wire value.
