Enum Constant Detail

ok

public static final HGListener.Result ok

This result indicates that processing should continue normally.

cancel

public static final HGListener.Result cancel

This result indicates that processing should be cancelled. When a listener returns a cancel result, event processing is interrupted and the calling HyperGraph instance is notified. The HyperGraph instance may or may not honor the cancellation depending on the particular event type. This per-event-type behavior is document in each event class.

Method Detail

values

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

Returns:

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

valueOf

public static HGListener.Result 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

toString

public String toString()

Overrides:

toString in class Enum<HGListener.Result>
