Method Detail

values

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

Returns:

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

valueOf

public static UpdateConfigurationPolicy 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

invokeStackAdvisor

public boolean invokeStackAdvisor()

applyIdentityChanges

public boolean applyIdentityChanges()

applyAdditions

public boolean applyAdditions()

applyOtherChanges

public boolean applyOtherChanges()

translate

public static String translate(UpdateConfigurationPolicy value)

Safely translates a UpdateConfigurationPolicy value to a String of all lowercase characters.

Parameters:

value - the value to translate

Returns:

null if the input is null; otherwise the String value of the policy enum converted to lowercase characters.

translate

public static UpdateConfigurationPolicy translate(String stringValue)

Safely translates a String value to an UpdateConfigurationPolicy.

The input value will be trimmed and converted to all uppercase characters. If "-"'s are used instead of "_"'s, they will be converted.

Parameters:

stringValue - the String to translate

Returns:

The translated UpdateConfigurationPolicy value; or null if a translation cannot be made
