Enum Constant Detail

OK

public static final JsonV1SampleSerializer.Severity OK

OK. Typically, this means that there was no alarm condition present when the sample was archived.

MINOR

public static final JsonV1SampleSerializer.Severity MINOR

Minor alarm. Typically, this means that a minor alarm condition (e.g. a warning) was present when the sample was archived.

MAJOR

public static final JsonV1SampleSerializer.Severity MAJOR

Major alarm. Typically, this means that a major alarm condition (e.g. an alarm indicating a serious problem) was present when the sample was archived.

INVALID

public static final JsonV1SampleSerializer.Severity INVALID

Invalid alarm. Typically, this indicates that the alarm status (and possibly also the value) of the archived process variable was unknown when the sample was archived. For example, such an alarm condition might be present when the connection to the sub-system hosting the process variable is interrupted.

Method Detail

values

public static JsonV1SampleSerializer.Severity[] 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 (JsonV1SampleSerializer.Severity c : JsonV1SampleSerializer.Severity.values())
    System.out.println(c);

Returns:

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

valueOf

public static JsonV1SampleSerializer.Severity 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
