Enum Constant Detail

UNKNOWN

public static final RequestFailureReason UNKNOWN

The reason for the failure was none of the below reasons or was not recorded by the data node.

READ_TOO_MANY_TOMBSTONES

public static final RequestFailureReason READ_TOO_MANY_TOMBSTONES

The data node read too many tombstones when attempting to execute a read query (see tombstone_failure_threshold).

Field Detail

code

public final int code

The code to be serialized as an unsigned 16 bit integer

VALUES

public static final RequestFailureReason[] VALUES

Method Detail

values

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

Returns:

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

valueOf

public static RequestFailureReason 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
