Class AotObjectCachingExamples

java.lang.Object

net.jrodolfo.java_evolution.java26.aot_object_caching.AotObjectCachingExamples

public class AotObjectCachingExamples
extends Object

Demonstrates the Java 26 AOT object-caching command-line workflow.

The example launches a tiny source file in a child JVM with -XX:AOTCacheOutput, then launches it again with -XX:AOTCache. It verifies cache creation and reuse, not startup performance.

runAotObjectCachingWorkflow

public AotObjectCachingExamples.AotObjectCachingWorkflowResult runAotObjectCachingWorkflow(Path workspace)
                                                                                    throws IOException,
InterruptedException

Creates and then uses an AOT object cache in a temporary workspace.

Parameters:

workspace - temporary directory for generated source and cache files

Returns:

results from both child-JVM runs and the generated cache metadata

Throws:

IOException - when the source cannot be written or a child process cannot be started

InterruptedException - when waiting for a child process is interrupted

probeSource

public String probeSource()

Source code used by the child JVM.

Returns:

a small source-launcher program with stable output markers

problem

public String problem()

Explains the startup problem addressed by AOT object caching.

Returns:

a short problem statement

java26Idea

public String java26Idea()

Describes the Java 26 idea.

Returns:

a short feature explanation

testBoundary

public String testBoundary()

Explains the boundary of this executable example.

Returns:

a short test-boundary explanation
