Constructor Details

EngineClassLoader

public EngineClassLoader()

Constructs a new EngineClassLoader.

EngineClassLoader

@Incubating
public EngineClassLoader(CompilerConfiguration configuration)

Constructs an EngineClassLoader with the given compiler configuration and the current thread's context class loader as parent.

Parameters:

configuration - compiler configuration, or null for the default

Since:

7.0.0

EngineClassLoader

@Incubating
public EngineClassLoader(ClassLoader parent)

Constructs an EngineClassLoader with the given parent class loader and CompilerConfiguration.DEFAULT. Use EngineClassLoader(ClassLoader, CompilerConfiguration) to supply an engine's configuration, so that the engine adopts this loader rather than wrapping it.

Parameters:

parent - the parent class loader

Since:

7.0.0

EngineClassLoader

@Incubating
public EngineClassLoader(ClassLoader parent,
 CompilerConfiguration configuration)

Constructs an EngineClassLoader with the given parent class loader and compiler configuration.

Parameters:

parent - the parent class loader

configuration - compiler configuration, or null for the default

Since:

7.0.0

Method Details

getPackages

public Package[] getPackages()

Returns all packages loaded by this class loader.

Overrides:

getPackages in class ClassLoader

Returns:

array of packages

purgeClassCache

public void purgeClassCache(String regex)

Purges cached classes matching the given regex pattern.

Parameters:

regex - the pattern to match class names

purgeClassCache

public void purgeClassCache()

Purges all dynamically generated script classes from the cache.
