Enum TableCharacteristic.Semantics

All Implemented Interfaces:
Serializable, Comparable<TableCharacteristic.Semantics>, Constable
Enclosing class:

public static enum TableCharacteristic.Semantics extends Enum<TableCharacteristic.Semantics>
Input table has either row semantics or set semantics.
  • Enum Constant Details

    • ROW

      public static final TableCharacteristic.Semantics ROW
      Row semantics means that the result of the Window TableFunction is decided on a row-by-row basis. As an extreme example, the DBMS could atomize the input table into individual rows, and send each single row to a different virtual processor.
    • SET

      public static final TableCharacteristic.Semantics SET
      Set semantics means that the outcome of the Window TableFunction depends on how the data is partitioned. A partition may not be split across virtual processors, nor may a virtual processor handle more than one partition.
  • Method Details

    • values

      public static TableCharacteristic.Semantics[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static TableCharacteristic.Semantics valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
