  • Method Details

    • hasColumns

      public final boolean hasColumns()
      For responses, this returns true if the service returned a value for the Columns property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • columns

      public final List<Column> columns()

      The columns for the relation that this schema represents.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumns() method.

      Returns:
      The columns for the relation that this schema represents.

    • hasPartitionKeys

      public final boolean hasPartitionKeys()
      For responses, this returns true if the service returned a value for the PartitionKeys property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • partitionKeys

      public final List<Column> partitionKeys()

      The partition keys for the dataset underlying this schema.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPartitionKeys() method.

      Specified by:
      sdkFields in interface SdkPojo
      Returns:
