Enum ColumnAuthority

Object

Enum<ColumnAuthority>

gudusoft.gsqlparser.resolver2.binding.ColumnAuthority

All Implemented Interfaces:

Serializable, Comparable<ColumnAuthority>

public enum ColumnAuthority
extends Enum<ColumnAuthority>

Column-level authority verdict returned by BindingMetadataAuthority.lookup(gudusoft.gsqlparser.resolver2.namespace.INamespace, java.lang.String).

Slice S4 (plan §5.5). The post-pass uses this verdict to decide whether a missing column may emit UNKNOWN_COLUMN: only an AUTHORITATIVE_ABSENT verdict justifies the diagnostic.

Made public so resume documents and future post-pass code in sibling packages can name the verdict; not surfaced through any documented binding API method (see plan §5.7 — public ResolutionResult accessor remains rejected).

Enum Constant Summary

Enum Constants

Enum Constant and Description
AUTHORITATIVE_ABSENT The catalog authoritatively declares the column does NOT exist on a namespace whose metadata state is MetadataState.FOUND.
AUTHORITATIVE_PRESENT The catalog authoritatively declares the column exists.
METADATA_UNAVAILABLE The catalog cannot make an authoritative claim — namespace state is METADATA_UNAVAILABLE or NOT_FOUND_IN_CATALOG, the column lookup is ambiguous, or inputs were null.

Method Summary

Modifier and Type	Method and Description
static ColumnAuthority	valueOf(String name) Returns the enum constant of this type with the specified name.
static ColumnAuthority[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

AUTHORITATIVE_PRESENT

public static final ColumnAuthority AUTHORITATIVE_PRESENT

The catalog authoritatively declares the column exists.

AUTHORITATIVE_ABSENT

public static final ColumnAuthority AUTHORITATIVE_ABSENT

The catalog authoritatively declares the column does NOT exist on a namespace whose metadata state is MetadataState.FOUND.

METADATA_UNAVAILABLE

public static final ColumnAuthority METADATA_UNAVAILABLE

The catalog cannot make an authoritative claim — namespace state is METADATA_UNAVAILABLE or NOT_FOUND_IN_CATALOG, the column lookup is ambiguous, or inputs were null. Strict mode may emit CATALOG_METADATA_UNAVAILABLE (WARNING); never UNKNOWN_COLUMN.

Method Detail

values

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

Returns:

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

valueOf

public static ColumnAuthority 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
