Enum Constant Detail

NEW

public static final RecordingState NEW

The initial state when a Recording is created.

DELAYED

public static final RecordingState DELAYED

The recording is scheduled to start, but with a start time that has not yet happened. An invocation of Recording.start() will transition the recording into the RUNNING state.

RUNNING

public static final RecordingState RUNNING

The recording is recording data and an invocation of Recording.stop() will transition the recording into the STOPPED state.

STOPPED

public static final RecordingState STOPPED

The recording is stopped, but it's holding on to recorded data that can be dumped to disk. An invocation of Recording.close() will release the data and transition the recording into the CLOSED state.

CLOSED

public static final RecordingState CLOSED

The recording is closed and all resources associated with the recording have been released. There is nothing that can be done with it from this point, and it's no longer available from FlightRrecorder.getRecordings() .

Method Detail

values

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

Returns:

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

valueOf

public static RecordingState 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
