PLANNED

public static final FragmentInstanceState PLANNED

Instance is planned but has not been scheduled yet. An instance will be in the planned state until, the dependencies of the instance have begun producing output.

RUNNING

public static final FragmentInstanceState RUNNING

Instance is running.

FLUSHING

public static final FragmentInstanceState FLUSHING

Instance has finished executing and output is left to be consumed. In this state, there will be no new drivers, the existing drivers have finished and the output buffer of the instance is at-least in a 'no-more-tsBlocks' state.

FINISHED

public static final FragmentInstanceState FINISHED

Instance has finished executing and all output has been consumed.

CANCELLED

public static final FragmentInstanceState CANCELLED

Instance was canceled by a user.

ABORTED

public static final FragmentInstanceState ABORTED

Instance was aborted due to a failure in the query. The failure was not in this instance.

FAILED

public static final FragmentInstanceState FAILED

Instance execution failed.

NO_SUCH_INSTANCE

public static final FragmentInstanceState NO_SUCH_INSTANCE

Instance is not found.

Method Detail

values

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

Returns:

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

valueOf

public static FragmentInstanceState 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

isDone

public boolean isDone()

Is this a terminal state.

isFailed

public boolean isFailed()
