• getUnsupportedFeatures

  public static Map<String,String> getUnsupportedFeatures(HColumnDescriptor columnDescriptor)

  Build a Map of configuration keys and values describing configuration values we don't support.

  Parameters:

  columnDescriptor - a HColumnDescriptor object.

• throwIfRequestingUnknownFeatures

  public static void throwIfRequestingUnknownFeatures(HColumnDescriptor columnDescriptor)

  Throw an UnsupportedOperationException if the column descriptor cannot be adapted due to it having unknown configuration keys.

  Parameters:

  columnDescriptor - a HColumnDescriptor object.

• throwIfRequestingUnsupportedFeatures

  public static void throwIfRequestingUnsupportedFeatures(HColumnDescriptor columnDescriptor)

  Throw an UnsupportedOperationException if the column descriptor cannot be adapted due to it having configuration values that are not supported.

  Parameters:

  columnDescriptor - a HColumnDescriptor object.

• buildGarbageCollectionRule

  public static com.google.cloud.bigtable.admin.v2.models.GCRules.GCRule buildGarbageCollectionRule(HColumnDescriptor columnDescriptor)

  Construct an Bigtable GCRules.GCRule from the given column descriptor.

  Parameters:

  columnDescriptor - a HColumnDescriptor object.

  Returns:

  a GCRules.GCRule object.

• processIntersection

  protected static void processIntersection(com.google.bigtable.admin.v2.GcRule gcRule,
                                            HColumnDescriptor columnDescriptor)

  processIntersection.

  Parameters:

  gcRule - a GcRule object.

  columnDescriptor - a HColumnDescriptor object.

• adapt

  public com.google.bigtable.admin.v2.ColumnFamily adapt(HColumnDescriptor columnDescriptor)

  Adapt a single instance of an HBase HColumnDescriptor to an instance of ColumnFamily.Builder.

  NOTE: This method does not set the name of the ColumnFamily.Builder. The assumption is that the CreateTableRequest or CreateColumnFamilyRequest takes care of the naming. As of now (3/11/2015), the server insists on having a blank name.

  Parameters:

  columnDescriptor - a HColumnDescriptor object.

  Returns:

  a ColumnFamily.Builder object.

• adapt

  public HColumnDescriptor adapt(com.google.cloud.bigtable.admin.v2.models.ColumnFamily columnFamily)

  Convert a Bigtable ColumnFamily to an HBase HColumnDescriptor. See convertGarbageCollectionRule(GcRule, HColumnDescriptor) for more info.

  Parameters:

  columnFamily - a ColumnFamily object.

  Returns:

  a HColumnDescriptor object.
