Enum ByteArrayClassLoader.PersistenceHandler

java.lang.Object

java.lang.Enum<ByteArrayClassLoader.PersistenceHandler>

net.bytebuddy.dynamic.loading.ByteArrayClassLoader.PersistenceHandler

All Implemented Interfaces:

Serializable, Comparable<ByteArrayClassLoader.PersistenceHandler>

Enclosing class:

ByteArrayClassLoader

public static enum ByteArrayClassLoader.PersistenceHandler
extends Enum<ByteArrayClassLoader.PersistenceHandler>

A persistence handler decides on weather the byte array that represents a loaded class is exposed by the ClassLoader.getResourceAsStream(String) method.

Enum Constant Summary

Enum Constants

Enum Constant and Description
LATENT The latent persistence handler hides all class file representations and does not make them accessible even before they are loaded.
MANIFEST The manifest persistence handler retains all class file representations and makes them accessible.

Method Summary

Modifier and Type	Method and Description
protected abstract InputStream	inputStream(String resourceName, Map<String,byte[]> typeDefinitions) Performs a lookup of an input stream for exposing a class file as a resource.
boolean	isManifest() Checks if this persistence handler represents manifest class file storage.
protected abstract byte[]	lookup(String name, Map<String,byte[]> typeDefinitions) Performs a lookup of a class file by its name.
static ByteArrayClassLoader.PersistenceHandler	valueOf(String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

MANIFEST

public static final ByteArrayClassLoader.PersistenceHandler MANIFEST

The manifest persistence handler retains all class file representations and makes them accessible.

LATENT

public static final ByteArrayClassLoader.PersistenceHandler LATENT

The latent persistence handler hides all class file representations and does not make them accessible even before they are loaded.

Method Detail

values

public static ByteArrayClassLoader.PersistenceHandler[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ByteArrayClassLoader.PersistenceHandler c : ByteArrayClassLoader.PersistenceHandler.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ByteArrayClassLoader.PersistenceHandler valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isManifest

public boolean isManifest()

Checks if this persistence handler represents manifest class file storage.

Returns:

true if this persistence handler represents manifest class file storage.

lookup

protected abstract byte[] lookup(String name,
                                 Map<String,byte[]> typeDefinitions)

Performs a lookup of a class file by its name.

Parameters:

name - The name of the class to be loaded.

typeDefinitions - A map of fully qualified class names pointing to their binary representations.

Returns:

The byte array representing the requested class or null if no such class is known.

inputStream

protected abstract InputStream inputStream(String resourceName,
                                           Map<String,byte[]> typeDefinitions)

Performs a lookup of an input stream for exposing a class file as a resource.

Parameters:

resourceName - The resource name of the class to be exposed as its class file.

typeDefinitions - A map of fully qualified class names pointing to their binary representations.

Returns:

An input stream representing the requested resource or null if no such resource is known.
