public enum ExpectedRevisionConstants
extends java.lang.Enum<ExpectedRevisionConstants>
implements com.google.protobuf.ProtocolMessageEnum

 Constants for expected revision validation in optimistic concurrency control.
 These can be used in the expected_revision field, or you can specify an actual revision number.

Enum Constant Detail

EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT

public static final ExpectedRevisionConstants EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT

 The stream must have exactly one event at revision 0.
 Used for scenarios requiring strict single-event semantics.
 

EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT = 0;

EXPECTED_REVISION_CONSTANTS_NO_STREAM

public static final ExpectedRevisionConstants EXPECTED_REVISION_CONSTANTS_NO_STREAM

 The stream must not exist yet (first write to the stream).
 Fails if the stream already has events.
 

EXPECTED_REVISION_CONSTANTS_NO_STREAM = -1;

EXPECTED_REVISION_CONSTANTS_ANY

public static final ExpectedRevisionConstants EXPECTED_REVISION_CONSTANTS_ANY

 Accept any current state of the stream (no optimistic concurrency check).
 The write will succeed regardless of the stream's current revision.
 

EXPECTED_REVISION_CONSTANTS_ANY = -2;

EXPECTED_REVISION_CONSTANTS_EXISTS

public static final ExpectedRevisionConstants EXPECTED_REVISION_CONSTANTS_EXISTS

 The stream must exist (have at least one record).
 Fails if the stream doesn't exist yet.
 

EXPECTED_REVISION_CONSTANTS_EXISTS = -4;

UNRECOGNIZED

public static final ExpectedRevisionConstants UNRECOGNIZED

Field Detail

EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT_VALUE

public static final int EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT_VALUE

 The stream must have exactly one event at revision 0.
 Used for scenarios requiring strict single-event semantics.
 

EXPECTED_REVISION_CONSTANTS_SINGLE_EVENT = 0;

Method Detail

values

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

Returns:

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

valueOf

public static ExpectedRevisionConstants 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

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 ExpectedRevisionConstants valueOf(int value)

Deprecated. Use forNumber(int) instead.

Parameters:

value - The numeric wire value of the corresponding enum entry.

Returns:

The enum associated with the given numeric wire value.

forNumber

public static ExpectedRevisionConstants forNumber(int value)

Parameters:

value - The numeric wire value of the corresponding enum entry.

Returns:

The enum associated with the given numeric wire value.

internalGetValueMap

Specified by:

getDescriptorForType in interface com.google.protobuf.ProtocolMessageEnum

getDescriptor
