Enum Constant Detail

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 Detail

KIND_UNSPECIFIED_VALUE

public static final int KIND_UNSPECIFIED_VALUE

 Not specified.
 

KIND_UNSPECIFIED = 0;

Constant Field Values

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;

Constant Field Values

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;

Method Detail

values

public static PlanNode.Kind[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PlanNode.Kind c : PlanNode.Kind.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PlanNode.Kind valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getNumber

public final int getNumber()

Specified by:

getNumber in interface Internal.EnumLite

Specified by:

getNumber in interface ProtocolMessageEnum

valueOf

@Deprecated
public static PlanNode.Kind valueOf(int value)

Deprecated. Use forNumber(int) instead.

forNumber

public static PlanNode.Kind forNumber(int value)
