Enum Constant Detail

LAZY_FROM_SOURCES

public static final ScheduleMode LAZY_FROM_SOURCES

Schedule tasks lazily from the sources. Downstream tasks are started once their input data are ready

EAGER

public static final ScheduleMode EAGER

Schedules all tasks immediately.

Method Detail

values

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

Returns:

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

valueOf

public static ScheduleMode 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

allowLazyDeployment

public boolean allowLazyDeployment()

Returns whether we are allowed to deploy consumers lazily.
