Interface RecorderContext

All Known Implementing Classes:

BytecodeRecorderImpl

public interface RecorderContext

An injectable utility class that contains methods that can be needed for dealing with recorders.

Method Summary

Modifier and Type	Method	Description
Class<?>	classProxy(String name)	Deprecated. This construct should not be needed in most use cases since directly loading deployment/application classes at processing time in build steps is safe.
<T> RuntimeValue<T>	newInstance(String name)	Creates a RuntimeValue object that represents an object created via the default constructor.
<T> void	registerNonDefaultConstructor(Constructor<T> constructor, Function<T,List<Object>> parameters)	Registers a way to construct an object via a non-default constructor.
void	registerObjectLoader(ObjectLoader loader)	Register an object loader.
<F, T> void	registerSubstitution(Class<F> from, Class<T> to, Class<? extends ObjectSubstitution<? super F,? super T>> substitution)	Registers a substitution to allow objects that are not serializable to bytecode to be substituted for an object that is.

Method Details

registerNonDefaultConstructor

<T> void registerNonDefaultConstructor(Constructor<T> constructor,
 Function<T,List<Object>> parameters)

Registers a way to construct an object via a non-default constructor. Each object may only have at most one non-default constructor registered

Type Parameters:

T - The type of the object

Parameters:

constructor - The constructor

parameters - A function that maps the object to a list of constructor parameters

registerSubstitution

<F,
T> void registerSubstitution(Class<F> from,
 Class<T> to,
 Class<? extends ObjectSubstitution<? super F,? super T>> substitution)

Registers a substitution to allow objects that are not serializable to bytecode to be substituted for an object that is.

Parameters:

from - The class of the non-serializable object

to - The class to serialize to

substitution - The subclass of ObjectSubstitution that performs the substitution

registerObjectLoader

void registerObjectLoader(ObjectLoader loader)

Register an object loader.

Parameters:

loader - the object loader (must not be null)

classProxy

@Deprecated(forRemoval=false)
Class<?> classProxy(String name)

Deprecated.

This construct should not be needed in most use cases since directly loading deployment/application classes at processing time in build steps is safe. However, there are use cases where this method comes in handy, such as referring to classes that were generated in previous build steps using GeneratedClassBuildItem.

Creates a Class instance that can be passed to a recording proxy as a substitute for a class that is not loadable at processing time. At runtime the actual class will be passed into the invoked method.

Parameters:

name - The fully-qualified class name

Returns:

A Class instance that can be passed to a recording proxy

newInstance

<T> RuntimeValue<T> newInstance(String name)

Creates a RuntimeValue object that represents an object created via the default constructor.

This object can be passed into recorders, but must not be used directly at deployment time

Type Parameters:

T - The type of the class

Parameters:

name - The name of the class

Returns:

The class instance proxy
