Enum Clone.Policy

java.lang.Enum<Clone.Policy>

com.lhkbob.entreri.property.Clone.Policy

All Implemented Interfaces:

Serializable, Comparable<Clone.Policy>

Enclosing class:

Clone

public static enum Clone.Policy
extends Enum<Clone.Policy>

Policy is an enum describing a number of different behaviors performed by a PropertyFactory when its PropertyFactory.clone(Property, int, Property, int) method is invoked in response to Entity.add(com.lhkbob.entreri.Component) or EntitySystem.addEntity(Entity).

Enum Constant Summary

Enum Constants

Enum Constant and Description
DISABLE Cloning policy that disables the clone action for the given property.
INVOKE_CLONE Cloning policy that attempts to invoke Object.clone() on cloned component's current value.
JAVA_DEFAULT Cloning policy that follows Java's assignment semantics, e.g.

Enum Constant Detail

DISABLE

public static final Clone.Policy DISABLE

Cloning policy that disables the clone action for the given property. The new component being cloned into gets the default value, just as if it was initialized via Entity.add(Class).

JAVA_DEFAULT

public static final Clone.Policy JAVA_DEFAULT

Cloning policy that follows Java's assignment semantics, e.g. primitives are copied by value from the component being cloned to the new one, and references are copied but the actual instances are shared.

This is the default policy if the Clone attribute is not present on any of the property implementations provided in this package.

INVOKE_CLONE

public static final Clone.Policy INVOKE_CLONE

Cloning policy that attempts to invoke Object.clone() on cloned component's current value. If the value is null, null is assigned without throwing an NPE.

If the property type is a primitive data type, or is not Cloneable, this behaves like JAVA_DEFAULT.

Method Detail

values

public static Clone.Policy[] 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 (Clone.Policy c : Clone.Policy.values())
    System.out.println(c);

Returns:

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

valueOf

public static Clone.Policy 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
