Enum BytecodeGen.Visibility

java.lang.Object

java.lang.Enum<BytecodeGen.Visibility>

com.google.inject.internal.BytecodeGen.Visibility

All Implemented Interfaces:

Serializable, Comparable<BytecodeGen.Visibility>

Enclosing class:

BytecodeGen

public static enum BytecodeGen.Visibility
extends Enum<BytecodeGen.Visibility>

The required visibility of a user's class from a Guice-generated class. Visibility of package-private members depends on the loading classloader: only if two classes were loaded by the same classloader can they see each other's package-private members. We need to be careful when choosing which classloader to use for generated classes. We prefer our bridge classloader, since it's OSGi-safe and doesn't leak permgen space. But often we cannot due to visibility.

Enum Constant Summary

Enum Constants

Enum Constant and Description
PUBLIC Indicates that Guice-generated classes only need to call and override public members of the target class.
SAME_PACKAGE Indicates that Guice-generated classes need to call or override package-private members.

Enum Constant Detail

PUBLIC

public static final BytecodeGen.Visibility PUBLIC

Indicates that Guice-generated classes only need to call and override public members of the target class. These generated classes may be loaded by our bridge classloader.

SAME_PACKAGE

public static final BytecodeGen.Visibility SAME_PACKAGE

Indicates that Guice-generated classes need to call or override package-private members. These generated classes must be loaded in the same classloader as the target class. They won't work with OSGi, and won't get garbage collected until the target class' classloader is garbage collected.

Method Detail

values

public static BytecodeGen.Visibility[] 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 (BytecodeGen.Visibility c : BytecodeGen.Visibility.values())
    System.out.println(c);

Returns:

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

valueOf

public static BytecodeGen.Visibility 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
