Method Detail

currentClientHasMinimumVersion

public static boolean currentClientHasMinimumVersion(int major,
                                                     int minor)

hasMinimumVersion

public static boolean hasMinimumVersion(org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.VersionInfo versionInfo,
                                        int major,
                                        int minor)

getCurrentClientVersionInfo

private static org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.VersionInfo getCurrentClientVersionInfo()

Returns:

the versionInfo extracted from the current RpcCallContext

getCurrentClientVersionNumber

public static int getCurrentClientVersionNumber()

Returns:

the version number extracted from the current RpcCallContext as int. (e.g. 0x0103004 is 1.3.4)

versionNumberToString

public static String versionNumberToString(int version)

Parameters:

version -

Returns:

the passed-in version int as a version String (e.g. 0x0103004 is 1.3.4)

getVersionNumber

public static int getVersionNumber(org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.VersionInfo versionInfo)

Pack the full number version in a int. by shifting each component by 8bit, except the dot release which has 12bit. Examples: (1.3.4 is 0x0103004, 2.1.0 is 0x0201000)

Parameters:

versionInfo - the VersionInfo object to pack

Returns:

the version number as int. (e.g. 0x0103004 is 1.3.4)

buildVersionNumber

private static int buildVersionNumber(int major,
                                      int minor,
                                      int patch)

Pack the full number version in a int. by shifting each component by 8bit, except the dot release which has 12bit. Examples: (1.3.4 is 0x0103004, 2.1.0 is 0x0201000)

Parameters:

major - version major number

minor - version minor number

patch - version patch number

Returns:

the version number as int. (e.g. 0x0103004 is 1.3.4)

getVersionComponents

private static String[] getVersionComponents(org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.VersionInfo versionInfo)

Returns the version components Examples: "1.4.3" returns [1, 4, 3], "4.5.6-SNAPSHOT" returns [4, 5, 6, "SNAPSHOT"]

Returns:

the components of the version string
