Method Detail

convertToString

public static String convertToString(Set<String> namespaces)

convert

public static ReplicationProtos.TableCF[] convert(Map<TableName,? extends Collection<String>> tableCfs)

convert map to TableCFs Object

convertToString

public static String convertToString(Map<TableName,? extends Collection<String>> tableCfs)

convert

public static String convert(ReplicationProtos.TableCF[] tableCFs)

Convert TableCFs Object to String. Output String Format: ns1.table1:cf1,cf2;ns2.table2:cfA,cfB;table3
