Method Detail

values

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

Returns:

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

valueOf

public static DefaultSlotSharingResolver 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

Description copied from interface: SlotSharingResolver

Get the execution slot sharing groups for the job information based on the vertices parallelisms.

Specified by:

getExecutionSlotSharingGroups in interface SlotSharingResolver

Parameters:

jobInformation - the job information.

vertexParallelism - the parallelisms for the vertices of the job information.

Returns:

the all execution slot sharing groups for the deployment of the job.
