Class NativeImageUtil

java.lang.Object

com.fasterxml.jackson.databind.util.NativeImageUtil

public class NativeImageUtil
extends Object

Utilities for graal native image support; mostly to improve error message handling in case of missing information for native image.

Since:

2.14

Method Summary

Modifier and Type	Method	Description
static boolean	isInNativeImage()	Checks whether we're running in SubstrateVM native image only by the presence of "org.graalvm.nativeimage.imagecode" system property, regardless of its value (buildtime or runtime).
static boolean	isInNativeImageAndIsAtRuntime()	Check whether we're running in SubstrateVM native image and also in "runtime" mode.
static boolean	isUnsupportedFeatureError(Throwable e)	Check whether the given error is a substratevm UnsupportedFeatureError
static boolean	needsReflectionConfiguration(Class<?> cl)	Check whether the given class is likely missing reflection configuration (running in native image, and no members visible in reflection).

Method Details

isInNativeImageAndIsAtRuntime

public static boolean isInNativeImageAndIsAtRuntime()

Check whether we're running in SubstrateVM native image and also in "runtime" mode. The "runtime" check cannot be a constant, because the static initializer may run early during build time

As optimization, RUNNING_IN_SVM is used to short-circuit on normal JVMs.

Since:

2.16

isInNativeImage

public static boolean isInNativeImage()

Checks whether we're running in SubstrateVM native image only by the presence of "org.graalvm.nativeimage.imagecode" system property, regardless of its value (buildtime or runtime). We are irrespective of the build or runtime phase, because native-image can initialize static initializers at build time.

Since:

2.16

isUnsupportedFeatureError

public static boolean isUnsupportedFeatureError(Throwable e)

Check whether the given error is a substratevm UnsupportedFeatureError

needsReflectionConfiguration

public static boolean needsReflectionConfiguration(Class<?> cl)

Check whether the given class is likely missing reflection configuration (running in native image, and no members visible in reflection).
