Version (Java driver for Scylla and Apache Cassandra(R)

java.lang.Object
- com.datastax.oss.driver.api.core.Version

All Implemented Interfaces:

Serializable, Comparable<Version>
```
@Immutable
public class Version
extends Object
implements Comparable<Version>, Serializable
```
A structured version number.
It is in the form X.Y.Z, with optional pre-release labels and build metadata.
Version numbers compare the usual way, the major number (X) is compared first, then the minor one (Y) and then the patch level one (Z). Lastly, versions with pre-release sorts before the versions that don't have one, and labels are sorted alphabetically if necessary. Build metadata are ignored for sorting versions.

  - parse
```
@Nullable
public static Version parse(@Nullable
                                      String version)
```
    Parses a version from a string.
    The version string should have primarily the form X.Y.Z to which can be appended one or more pre-release label after dashes (2.0.1-beta1, 2.1.4-rc1-SNAPSHOT) and an optional build label (2.1.0-beta1+a20ba.sha). Out of convenience, the "patch" version number, Z, can be omitted, in which case it is assumed to be 0.
    
    Parameters:
    
    version - the string to parse.
    
    Returns:
    
    the parsed version number.
    
    Throws:
    
    IllegalArgumentException - if the provided string does not represent a valid version.
  - getMajor
```
public int getMajor()
```
    The major version number.
    
    Returns:
    
    the major version number, i.e. X in X.Y.Z.
  - getMinor
```
public int getMinor()
```
    The minor version number.
    
    Returns:
    
    the minor version number, i.e. Y in X.Y.Z.
  - getPatch
```
public int getPatch()
```
    The patch version number.
    
    Returns:
    
    the patch version number, i.e. Z in X.Y.Z.
  - getDSEPatch
```
public int getDSEPatch()
```
    The DSE patch version number (will only be present for version of Cassandra in DSE).
    DataStax Entreprise (DSE) adds a fourth number to the version number to track potential hot fixes and/or DSE specific patches that may have been applied to the Cassandra version. In that case, this method returns that fourth number.
    
    Returns:
    
    the DSE patch version number, i.e. D in X.Y.Z.D, or -1 if the version number is not from DSE.
  - getPreReleaseLabels
```
public List<String> getPreReleaseLabels()
```
    The pre-release labels if relevant, i.e. label1 and label2 in X.Y.Z-label1-lable2.
    
    Returns:
    
    the pre-release labels. The return list will be null if the version number doesn't have any.
  - getBuildLabel
```
public String getBuildLabel()
```
    The build label if there is one.
    
    Returns:
    
    the build label or null if the version number doesn't have one.
  - nextStable
```
public Version nextStable()
```
    The next stable version, i.e. the version stripped of its pre-release labels and build metadata.
    This is mostly used during our development stage, where we test the driver against pre-release versions of Cassandra like 2.1.0-rc7-SNAPSHOT, but need to compare to the stable version 2.1.0 when testing for native protocol compatibility, etc.
    
    Returns:
    
    the next stable version.
  - compareTo
```
public int compareTo(@NonNull
                     Version other)
```
    Specified by:
    
    compareTo in interface Comparable<Version>
  - equals
```
public boolean equals(Object other)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
