Enum PropertySetter

java.lang.Object

java.lang.Enum<PropertySetter>

com.norconex.commons.lang.map.PropertySetter

All Implemented Interfaces:

Serializable, Comparable<PropertySetter>

public enum PropertySetter
extends Enum<PropertySetter>

Convenient way of handling the different ways a value (or values) can be set on a Properties instance.

XML configuration usage:

onSet="[append|prepend|replace|optional]"

The above is the recommended attribute for consuming classes to use in XML configuration.

Since:

2.0.0

Method Detail

values

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

Returns:

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

valueOf

public static PropertySetter 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
