public DestinationFromFileCreation(Path fileBeingCreated,
                                   io.reactivex.rxjava3.core.Single<? extends FileCreation> fileCreation)

Parameters:

fileBeingCreated -

fileCreation - A single representing the file creation and whose value is CACHED!

Method Detail

cancelCreation

public void cancelCreation()

Cancels this destination's underlying fileCreation process and cancel it Has no effect if the process already completed

Specified by:

cancelCreation in interface Destination

getFileCreation

public io.reactivex.rxjava3.core.Single<? extends FileCreation> getFileCreation()

getFileBeingCreated

public Path getFileBeingCreated()

The file being created once there is a subscription to the single

Returns:

transferTo

public FilterConfig transferTo(FilterEngine engine)

Specified by:

transferTo in interface Destination

prepareStream

public io.reactivex.rxjava3.core.Single<InputStreamSupplier> prepareStream()

Description copied from interface: Destination

This method requests a supplier for inputstreams. For basic destinations, such as FileDestination, this process does not involve any overhead. However, if the destination represents a workflow, prepareStream may trigger a complex execution. The execution may generate a file from which streams can be obtained, or nothing gets executed at this point, and execution only occur when opening an input stream.

Specified by:

prepareStream in interface Destination

Returns:

materialize

public io.reactivex.rxjava3.core.Single<DestinationFromFile> materialize(Supplier<Path> preferredPathCallback)

Description copied from interface: Destination

Materialize the destination to a given file. If the destination is already a file it waits until it has been completed. For non-file destinations, the callback is invoked to obtain a preferred file name

Specified by:

materialize in interface Destination

Returns:

getCreationStatus

public String getCreationStatus()

Description copied from interface: Destination

Get a description of the creation status.

Specified by:

getCreationStatus in interface Destination

Returns:
