MultipleParentClassLoader

public static class MultipleParentClassLoader.Builder
extends Object

A builder to collect class loader and that creates a MultipleParentClassLoader only if multiple or no ClassLoaders are found in the process.

Method Detail

append

public MultipleParentClassLoader.Builder append(Class<?>... type)

Appends the class loaders of the given types. The bootstrap class loader is implicitly skipped as it is an implicit parent of any class loader.

Parameters:

type - The types of which to collect the class loaders.

Returns:

A new builder instance with the additional class loaders of the provided types if they were not yet collected.

append

public MultipleParentClassLoader.Builder append(Collection<? extends Class<?>> types)

Appends the class loaders of the given types if those class loaders were not yet collected. The bootstrap class loader is implicitly skipped as it is an implicit parent of any class loader.

Parameters:

types - The types of which to collect the class loaders.

Returns:

A new builder instance with the additional class loaders.

append

public MultipleParentClassLoader.Builder append(ClassLoader... classLoader)

Appends the given class loaders if they were not yet collected. The bootstrap class loader is implicitly skipped as it is an implicit parent of any class loader.

Parameters:

classLoader - The class loaders to be collected.

Returns:

A new builder instance with the additional class loaders.

append

public MultipleParentClassLoader.Builder append(List<? extends ClassLoader> classLoaders)

Appends the given class loaders if they were not yet appended. The bootstrap class loader is never appended as it is an implicit parent of any class loader.

Parameters:

classLoaders - The class loaders to collected.

Returns:

A new builder instance with the additional class loaders.

filter

public MultipleParentClassLoader.Builder filter(ElementMatcher<? super ClassLoader> matcher)

Only retains all class loaders that match the given matcher.

Parameters:

matcher - The matcher to be used for filtering.

Returns:

A builder that does not longer consider any appended class loaders that matched the provided matcher.

build

public ClassLoader build()

Returns an appropriate class loader that represents all the collected class loaders using the current access control context.

Returns:

A suitable class loader.

build

public ClassLoader build(AccessControlContext accessControlContext)

Returns the only class loader that was appended if exactly one class loader was appended or a multiple parent class loader as a parent of all supplied class loader and with the bootstrap class loader as an implicit parent. If no class loader

Parameters:

accessControlContext - The access control context to be used for creating the class loader.

Returns:

A suitable class loader.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString
