Enum ChannelAccessStatus.StatusSeverityLevel

java.lang.Object

java.lang.Enum<ChannelAccessStatus.StatusSeverityLevel>

com.aquenos.epics.jackie.common.protocol.ChannelAccessStatus.StatusSeverityLevel

All Implemented Interfaces:

Serializable, Comparable<ChannelAccessStatus.StatusSeverityLevel>

Enclosing class:

ChannelAccessStatus

public static enum ChannelAccessStatus.StatusSeverityLevel
extends Enum<ChannelAccessStatus.StatusSeverityLevel>

Severity levels associated with status codes. The severity level indicates into which category a status code belongs. Usually, the behavior of a client does not depend on the severity level associated with a status code.

The EPICS C-library knows a severity level FATAL. Technically, this is just the ERROR level combined with the severe flag. In this implementation, the severe flag is kept separately in the ChannelAccessStatus.StatusSeverity, so that we can use an enum for the severity level.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ERROR Severity associated with messages that signal an error condition that is caused by a non-transient problem.
INFO Severity associated with messages that have an informational character and do not necessarily signal an error condition.
SUCCESS Reserved for the ChannelAccessStatus.StatusMessage.ECA_NORMAL message.
WARNING Severity associated with messages that signal an error condition that is might be transient.

Enum Constant Detail

SUCCESS

public static final ChannelAccessStatus.StatusSeverityLevel SUCCESS

Reserved for the ChannelAccessStatus.StatusMessage.ECA_NORMAL message.

INFO

public static final ChannelAccessStatus.StatusSeverityLevel INFO

Severity associated with messages that have an informational character and do not necessarily signal an error condition.

WARNING

public static final ChannelAccessStatus.StatusSeverityLevel WARNING

Severity associated with messages that signal an error condition that is might be transient. Usually this means that an operation failed, however the problem might resolve itself and it might make sense to retry later.

ERROR

public static final ChannelAccessStatus.StatusSeverityLevel ERROR

Severity associated with messages that signal an error condition that is caused by a non-transient problem. This means that an operation failed due to a permanent problem (e.g. an invalid parameter value sent by the client).

Method Detail

values

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

Returns:

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

valueOf

public static ChannelAccessStatus.StatusSeverityLevel 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
