    • getSelectedFieldsList

      public com.google.protobuf.ProtocolStringList getSelectedFieldsList()
       Optional. The names of the fields in the table to be returned. If no
 field names are specified, then all fields in the table are returned.

 Nested fields -- the child elements of a STRUCT field -- can be selected
 individually using their fully-qualified names, and will be returned as
 record fields containing only the selected nested fields. If a STRUCT
 field is specified in the selected fields list, all of the child elements
 will be returned.

 As an example, consider a table with the following schema:

   {
       "name": "struct_field",
       "type": "RECORD",
       "mode": "NULLABLE",
       "fields": [
           {
               "name": "string_field1",
               "type": "STRING",
 .              "mode": "NULLABLE"
           },
           {
               "name": "string_field2",
               "type": "STRING",
               "mode": "NULLABLE"
           }
       ]
   }

 Specifying "struct_field" in the selected fields list will result in a
 read session schema with the following logical structure:

   struct_field {
       string_field1
       string_field2
   }

 Specifying "struct_field.string_field1" in the selected fields list will
 result in a read session schema with the following logical structure:

   struct_field {
       string_field1
   }

 The order of the fields in the read session schema is derived from the
 table schema and does not correspond to the order in which the fields are
 specified in this list.
      repeated string selected_fields = 1;
      Specified by:
      getSelectedFieldsList in interface ReadOptions.TableReadOptionsOrBuilder
      Returns:
      A list containing the selectedFields.

    • getSelectedFieldsCount

      public int getSelectedFieldsCount()
       Optional. The names of the fields in the table to be returned. If no
 field names are specified, then all fields in the table are returned.

 Nested fields -- the child elements of a STRUCT field -- can be selected
 individually using their fully-qualified names, and will be returned as
 record fields containing only the selected nested fields. If a STRUCT
 field is specified in the selected fields list, all of the child elements
 will be returned.

               "type": "STRING",
 .              "mode": "NULLABLE"
           },
           {
               "name": "string_field2",
               "type": "STRING",
               "mode": "NULLABLE"
           }
       ]
   }

 Specifying "struct_field" in the selected fields list will result in a
 read session schema with the following logical structure:

   struct_field {
       string_field1
       string_field2
   }

 Specifying "struct_field.string_field1" in the selected fields list will
 result in a read session schema with the following logical structure:

   struct_field {
       string_field1
   }

 table schema and does not correspond to the order in which the fields are
 specified in this list.
      repeated string selected_fields = 1;
      Specified by:
      getSelectedFieldsCount in interface ReadOptions.TableReadOptionsOrBuilder
      Returns:
      The count of selectedFields.

    • getSelectedFields
