Method Summary

Modifier and TypeMethod and Description
protected ClassNameGenerator

Returns:

the class name generator
createClassNameGenerator()

Callback to customize the ClassNameGenerator.

protected ClassName

Returns:

the ClassName of the ApplicationContextInitializer entry point
doProcess()

Implements abstract org.springframework.context.aot.AbstractAotProcessor.doProcess.

Invoke the processing by clearing output directories first, followed by performAotProcessing(GenericApplicationContext).

protected Class<?>
getApplicationClass()

Get the application entry point (typically a class with a main() method).

protected List<String>

Returns:

the native image options to contribute
getDefaultNativeImageArguments(String

applicationClassName)

Return the native image arguments to use.

protected ClassName
performAotProcessing(GenericApplicationContext
the context to process
applicationContext)

Perform ahead-of-time processing of the specified context.

protected abstract GenericApplicationContext

Returns:

a non-refreshed GenericApplicationContext
prepareApplicationContext(Class<?> applicationClass)

ContextAotProcessorback to summary
protected ContextAotProcessor(Class<?> applicationClass, AbstractAotProcessor.Settings settings)

Create a new processor for the specified application entry point and common settings.

Parameters
applicationClass:Class<?>

the application entry point (class with a main() method)

settings:AbstractAotProcessor.Settings

the settings to apply

Method Detail

createClassNameGeneratorback to summary
protected ClassNameGenerator createClassNameGenerator()

Callback to customize the ClassNameGenerator.

By default, a standard ClassNameGenerator using the configured application entry point as the default target is used.

Returns:ClassNameGenerator

the class name generator

doProcessback to summary
protected ClassName doProcess()

Implements abstract org.springframework.context.aot.AbstractAotProcessor.doProcess.

Invoke the processing by clearing output directories first, followed by performAotProcessing(GenericApplicationContext).

Returns:ClassName

the ClassName of the ApplicationContextInitializer entry point

getApplicationClassback to summary
protected Class<?> getApplicationClass()

Get the application entry point (typically a class with a main() method).

getDefaultNativeImageArgumentsback to summary
protected List<String> getDefaultNativeImageArguments(String applicationClassName)

Return the native image arguments to use.

By default, the main class to use, as well as standard application flags are added.

If the returned list is empty, no native-image.properties is contributed.

Parameters
applicationClassName:String

the fully qualified class name of the application entry point

Returns:List<String>

the native image options to contribute

performAotProcessingback to summary
protected ClassName performAotProcessing(GenericApplicationContext applicationContext)

Perform ahead-of-time processing of the specified context.

Code, resources, and generated classes are stored in the configured output directories. In addition, run-time hints are registered for the application and its entry point.

Parameters
applicationContext:GenericApplicationContext

the context to process

prepareApplicationContextback to summary
protected abstract GenericApplicationContext prepareApplicationContext(Class<?> applicationClass)

Prepare the GenericApplicationContext for the specified application entry point to be used against an ApplicationContextAotGenerator.

Returns:GenericApplicationContext

a non-refreshed GenericApplicationContext
