Method Detail

logger

@Nonnull
ILogger logger()

Returns a logger for the associated ProcessorSupplier.

Specified by:

logger in interface ProcessorMetaSupplier.Context

memberIndex

int memberIndex()

Returns the index of the member among all the members that run this job: it's a unique cluster-wide index.

The value is in the range [0...memberCount-1].

attachedDirectory

@Nonnull
File attachedDirectory(@Nonnull
                                String id)

Uses the supplied ID to look up a directory you attached to the current Jet job. Creates a temporary directory with the same contents on the local cluster member and returns the location of the created directory. If the directory was already created, just returns its location.

Parameters:

id - the ID you used in a previous JobConfig.attachDirectory(java.net.URL) call

Since:

Jet 4.0

recreateAttachedDirectory

@Nonnull
File recreateAttachedDirectory(@Nonnull
                                        String id)

Behaves like attachedDirectory(java.lang.String), but if the directory already exists, it deletes and recreates all its contents.

Since:

Jet 4.3

attachedFile

@Nonnull
File attachedFile(@Nonnull
                           String id)

Parameters:

id - the ID you used in a previous JobConfig.attachFile(java.net.URL) call

Since:

Jet 4.0

recreateAttachedFile

@Nonnull
File recreateAttachedFile(@Nonnull
                                   String id)

Behaves like attachedFile(java.lang.String), but if the file already exists, it deletes and recreates it.

Since:

Jet 4.3

managedContext

@Nonnull
ManagedContext managedContext()

Returns ManagedContext associated with this job.

memberPartitions

@Nonnull
default int[] memberPartitions()
