Constructor Detail

Generator

public Generator(ClassLoader loader)

Parameters:

loader - ClassLoader owning generated classes

Method Detail

getPackageName

protected abstract String getPackageName()

Returns:

the name of the package of the generated class. Can be null.

getGeneratedClassName

public abstract String getGeneratedClassName()

Returns:

name of the generated class or interface

getAnchorClass

protected abstract Class<?> getAnchorClass()

Returns:

loadable class of the same package as getGeneratedClassName()

defineClassBody

protected abstract void defineClassBody()

Calls Wrapper methods to configure the class definition. The Wrapper uses ThreadLocal internally, so you should always call Wrapper._clear() in finally block after generation to avoid leakages.

getClassLoader

public ClassLoader getClassLoader()

Returns:

ClassLoader owning the generated class.

generate

public Class<?> generate()
                  throws IllegalAccessException

Generates the bytecode of the configured class with the usage of the PFL tool. Then uses MethodHandles or ClassGenerator to generate the class.

WARNING: This selection depends on the classloader capabilities and JVM rules, which change between JDK versions.

Returns:

Class

Throws:

IllegalAccessException

getPackageName

public static String getPackageName(String fullClassName)

Returns:

the package name or null.

getBaseName

public static String getBaseName(String fullClassName)

Returns:

simple class name (including wrapper class and dollar sign if it is internal class)

removeRedundantMethods

protected Method[] removeRedundantMethods(Method[] methods)

Remove duplicates from method array.

Duplicates will arise if a class/intf and super-class/intf define methods with the same signature. Potentially the throws clauses of the methods may be different (note Java requires that the superclass/intf method have a superset of the exceptions in the derived method).

Parameters:

methods -

Returns:

methods which can be generated in an interface
