Enum Constant Detail

CONVERT

public static final EmptyValueHandling CONVERT

Empty 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.EMPTY_VALUE (so even if converted, one could perform an instance comparison to specifically detect empty 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 EmptyValueHandling KEEP_AS_IS

Empty values will not be converted.

Method Detail

values

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

Returns:

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

valueOf

public static EmptyValueHandling 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
