PlanNode
public static enum PlanNode.Kind extends Enum<PlanNode.Kind> implements com.google.protobuf.ProtocolMessageEnum
 The kind of [PlanNode][google.spanner.v1.PlanNode]. Distinguishes between the two different kinds of
 nodes that can appear in a query plan.
Protobuf enum google.spanner.v1.PlanNode.Kind

  • Enum Constant Details

    • KIND_UNSPECIFIED

      public static final PlanNode.Kind KIND_UNSPECIFIED
       Not specified.
      KIND_UNSPECIFIED = 0;

    • RELATIONAL

      public static final PlanNode.Kind RELATIONAL
       Denotes a Relational operator node in the expression tree. Relational
 operators represent iterative processing of rows during query execution.
 For example, a `TableScan` operation that reads rows from a table.
      RELATIONAL = 1;

    • SCALAR

      public static final PlanNode.Kind SCALAR
       Denotes a Scalar node in the expression tree. Scalar nodes represent
 non-iterable entities in the query plan. For example, constants or
 arithmetic operators appearing inside predicate expressions or references
 to column names.
      SCALAR = 2;

    • UNRECOGNIZED

      public static final PlanNode.Kind UNRECOGNIZED

  • Field Details

    • KIND_UNSPECIFIED_VALUE

      public static final int KIND_UNSPECIFIED_VALUE
       Not specified.
      KIND_UNSPECIFIED = 0;

    • RELATIONAL_VALUE

      public static final int RELATIONAL_VALUE
       Denotes a Relational operator node in the expression tree. Relational
 operators represent iterative processing of rows during query execution.
 For example, a `TableScan` operation that reads rows from a table.
      RELATIONAL = 1;
      See Also:

    • SCALAR_VALUE

      public static final int SCALAR_VALUE
       Denotes a Scalar node in the expression tree. Scalar nodes represent
 non-iterable entities in the query plan. For example, constants or
 arithmetic operators appearing inside predicate expressions or references
 to column names.
      SCALAR = 2;

    • values

      public static PlanNode.Kind[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static PlanNode.Kind 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.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • getNumber

      public final int getNumber()
      Specified by:
      getNumber in interface com.google.protobuf.Internal.EnumLite
      Specified by:
      getNumber in interface com.google.protobuf.ProtocolMessageEnum

    • valueOf

      @Deprecated public static PlanNode.Kind valueOf(int value)
      Deprecated.
      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.)
      Parameters:
      value - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • forNumber

      public static PlanNode.Kind forNumber(int value)
      Parameters:
      value - The numeric wire value of the corresponding enum entry.
      Returns:
      The enum associated with the given numeric wire value.
