Enum AccessLevel

java.lang.Object

java.lang.Enum<AccessLevel>

com.inductiveautomation.opcua.types.AccessLevel

All Implemented Interfaces:

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

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

The AccessLevel Attribute is used to indicate how the Value of a Variable can be accessed (read/write) and if it contains current and/or historic data.

The AccessLevel does not take any user access rights into account, i.e. although the Variable is writable this may be restricted to a certain user / user group.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CurrentRead Indicates the current value is readable.
CurrentWrite Indicates the current value is writable.
HistoryRead Indicates the history of the value is readable.
HistoryWrite Indicates the history of the value is writable.
SemanticChange Indicates if the Variable used as Property generates SemanticsChangedEvents.

Indicates the current value is writable.

HistoryRead

public static final AccessLevel HistoryRead

Indicates the history of the value is readable.

Method Detail

values

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

Returns:

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

valueOf

public static AccessLevel 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

value

public byte value()

valueOfSet

public static byte valueOfSet(java.util.EnumSet<AccessLevel> levels)
