Method Detail

main

public static void main(String[] args)

installNativeImageClassLoader

public static NativeImageClassLoader installNativeImageClassLoader(String[] classpath)

Installs a class loader hierarchy that resolves classes and resources available in classpath. The parent for the installed NativeImageClassLoader is the default system class loader (jdk.internal.loader.ClassLoaders.AppClassLoader and sun.misc.Launcher.AppClassLoader for JDK8,11 respectively) In the presence of the custom system class loader NativeImageSystemClassLoader the delegate is to NativeImageClassLoader allowing the resolution of classes in classpath via the system class loader. Note that any custom system class loader has the default system class loader as its parent

Parameters:

classpath -

Returns:

the native image class loader

extractImageClassPath

public static String[] extractImageClassPath(List<String> arguments)

extractWatchPID

public static int extractWatchPID(List<String> arguments)

isValidJavaVersion

public static boolean isValidJavaVersion()

Unless the check should be ignored, check that I am running on JDK-8.

verifyValidJavaVersionAndPlatform

public static boolean verifyValidJavaVersionAndPlatform()

getJavaVersion

public static String getJavaVersion()

reportUserError

public static void reportUserError(String msg)

Function for reporting all fatal errors in SVM.

Parameters:

msg - error message that is printed.

reportUserError

public static void reportUserError(Throwable e,
                                   org.graalvm.compiler.options.OptionValues parsedHostedOptions)

Function for reporting all fatal errors in SVM.

Parameters:

e - error message that is printed.

parsedHostedOptions -

build

public int build(String[] args,
                 NativeImageClassLoader imageClassLoader)

Description copied from interface: ImageBuildTask

Main function for remote image building which is invoked on every image building request sent to the server. API NOTE: Standard error and standard output for image building will be reported remotely only if printed within this method. After build finishes, the static state of the JDK and NativeImageBuildServer must not have pointers to classes loaded by compilationClassLoader.

Specified by:

build in interface ImageBuildTask

Parameters:

args - arguments passed with the request to the SVM image builder

imageClassLoader - the classloader used for this image building task

Returns:

exit status of compilation

interruptBuild

public void interruptBuild()

Description copied from interface: ImageBuildTask

Requests interruption of the image build.

Specified by:

interruptBuild in interface ImageBuildTask
