QcowVersion (oVirt Java SDK 4.4.6 API)

java.lang.Object
- java.lang.Enum<QcowVersion>
- - org.ovirt.engine.sdk4.types.QcowVersion

All Implemented Interfaces:

Serializable, Comparable<QcowVersion>
```
public enum QcowVersion
extends Enum<QcowVersion>
```
The QCOW version specifies to the qemu which qemu version the volume supports. This field can be updated using the update API and will be reported only for QCOW volumes, it is determined by the storage domain's version which the disk is created on. Storage domains with version lower than V4 support QCOW2 version 2 volumes, while V4 storage domains also support QCOW2 version 3. For more information about features of the different QCOW versions, see http://wiki.qemu.org/Features/Qcow3[here].

  - values
```
public static QcowVersion[] 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 (QcowVersion c : QcowVersion.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static QcowVersion 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
  - value
