de.gebit.integrity.parameter.conversion.InexistentValueHandling

All Implemented Interfaces:

Serializable, Comparable<InexistentValueHandling>

public enum InexistentValueHandling
extends Enum<InexistentValueHandling>

This enum offers various ways in which inexistent values (InexistentValue) may be handled during conversion.

Enum Constant Detail

CONVERT

public static final InexistentValueHandling CONVERT

Inexistent values should be converted normally - which most likely means they will end up as a String. However, the String won't be just any object, but the specific, reserved instance ParameterUtil.INEXISTENT_VALUE (so even if converted, one could perform an instance comparison to specifically detect inexistent values - however, this is discouraged and should only be used if it is not possible to simply turn off conversion of inexistent values via KEEP_AS_IS).

This is the default if not specified otherwise in a ConversionContext.

KEEP_AS_IS

public static final InexistentValueHandling KEEP_AS_IS

Inexistent values will not be converted.

Method Detail

values

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

Returns:

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

valueOf

public static InexistentValueHandling 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
