Method Detail

values

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

Returns:

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

valueOf

public static Priority 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

getValue

public int getValue()

Returns the numeric value that backs this priority. These values are only important in deciding the relative distance between priorities.

Returns:

the numeric value of this priority

getDefaultPriority

public static Priority getDefaultPriority()

Returns the default Priority used by the system.

Returns:

the default Priority

higher

public abstract Priority higher()

Returns the priority that is higher than this priority, or this priority if this priority is the highest priority defined.

Returns:

the priority higher than this priority, or this priority if this is the highest priority

lower

public abstract Priority lower()

Returns the priority that is lower than this priority, or this priority if this priority is the lowest priority defined.

Returns:

the priority lower than this priority, or this priority if this is the lowest priority
