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.
