Enum<StructKind>

gudusoft.gsqlparser.resolver2.StructKind

All Implemented Interfaces:

Serializable, Comparable<StructKind>

public enum StructKind
extends Enum<StructKind>

Defines how fields of a structured type are accessed. Based on Apache Calcite's StructKind.

Enum Constant Summary

Enum Constants

Enum Constant and Description
FULLY_QUALIFIED Fully qualified access required.
NONE No special struct semantics.
PEEK_FIELDS Fields are implicitly available without qualification.
PEEK_FIELDS_DEFAULT Fields must be accessed via the qualifier.

Enum Constant Detail

FULLY_QUALIFIED

public static final StructKind FULLY_QUALIFIED

Fully qualified access required. Example: SELECT table.column FROM table

PEEK_FIELDS

public static final StructKind PEEK_FIELDS

Fields are implicitly available without qualification. Example: In FROM (SELECT id, name FROM users) t, the fields id and name are implicitly available.

PEEK_FIELDS_DEFAULT

public static final StructKind PEEK_FIELDS_DEFAULT

Fields must be accessed via the qualifier. Example: SELECT t.* FROM table t

NONE

public static final StructKind NONE

No special struct semantics.

Method Detail

values

public static StructKind[] 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 (StructKind c : StructKind.values())
    System.out.println(c);

Returns:

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

valueOf

public static StructKind 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
