Enum Constant Detail

NEW

public static final Trigger.WindowStatus NEW

The arrival of this element started a new pane. Either the window is entirely new, or we had previously fired a trigger that caused us to output the earlier elements.

EXISTING

public static final Trigger.WindowStatus EXISTING

This element was added to a pane that was already being managed.

UNKNOWN

public static final Trigger.WindowStatus UNKNOWN

The window set doesn’t track the windows being managed, so it is not known whether the pane is new. The trigger can track windows on its own if necessary.

Method Detail

values

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

Returns:

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

valueOf

public static Trigger.WindowStatus valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
