Enum CatalogLoadingMode

Object

Enum<CatalogLoadingMode>

gudusoft.gsqlparser.catalog.input.CatalogLoadingMode

All Implemented Interfaces:

Serializable, Comparable<CatalogLoadingMode>

public enum CatalogLoadingMode
extends Enum<CatalogLoadingMode>

Controls when a CatalogProvider fetches metadata.

Plan §10.1. Decision matrix:

• EAGER — provider materializes everything at open(); tests, small catalogs.
• LAZY — provider materializes nothing; on-miss fetch per CatalogQuery.
• AUTO — eager up to maxEagerObjects, then lazy; live providers.

Phase 1A skeleton — used as parameter type by Phase 1B+ implementations.

Method Detail

values

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

Returns:

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

valueOf

public static CatalogLoadingMode 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
