Package dev.frostlake.executor.udf

Class UdfRuntimes

java.lang.Object

dev.frostlake.executor.udf.UdfRuntimes

public final class UdfRuntimes
extends Object

Registry of the UdfLanguageRuntime providers on the classpath, discovered once at first use. A language whose runtime module is absent fails lazily — at CALL time, not at CREATE or catalog-restore time — with an error naming the module to add, so catalogs holding e.g. Python functions still load on a JavaScript-only deployment.

Method Summary

Modifier and Type	Method	Description
static Iterable<UdfLanguageRuntime>	all()	Every discovered runtime, for engine-construction configuration.
static UdfLanguageRuntime	installed(UdfLanguage language)	The runtime for language, or null when no module provides it.
static UdfLanguageRuntime	require(UdfLanguage language)	The runtime for language, or a clear error naming the module that provides it.

Method Details

all

public static Iterable<UdfLanguageRuntime> all()

Every discovered runtime, for engine-construction configuration.

installed

public static UdfLanguageRuntime installed(UdfLanguage language)

The runtime for language, or null when no module provides it. Unlike require(dev.frostlake.metastore.model.UdfLanguage), this is for callers that carry on without one — a CREATE-time body check can only judge a body whose language is installed, and accepts it otherwise.

require

public static UdfLanguageRuntime require(UdfLanguage language)

The runtime for language, or a clear error naming the module that provides it.
