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)

callWithVersion

public static <T1,T2,R,E extends Throwable> R callWithVersion(VersionInfoUtil.ServiceCallFunction<T1,T2,R,E> f,
                                                              T1 t1,
                                                              T2 t2)
                                                       throws E extends Throwable

Throws:

E extends Throwable

getCurrentClientVersionInfo

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

Returns:

the versionInfo extracted from the current RpcCallContext

versionNumberToString

public static String versionNumberToString(int version)

n * @return 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)
