Constructor and Description
FilterExecutionJava(Function<InputStream,InputStream> processor, Destination source)

Method Summary

Modifier and Type	Method and Description
io.reactivex.rxjava3.core.Single<InputStreamSupplier>	execStream() Ideally, premature closing of the input stream should propagate upstream and terminate any transformation processes upstream
FilterConfig	ifNeedsFileInput(Supplier<Path> pathRequester, BiConsumer<Path,FileWritingProcess> processCallback) Same as execStream() as this execution engine will never ask for the creation of temporary files
FilterConfig	ifNeedsFileOutput(Supplier<Path> pathRequester, BiConsumer<Path,FileWritingProcess> processCallback)
DestinationFromFileCreation	outputToFile(Path path) If explicit output to a file is requested, the handler set via ifNeedsFileOutput will not be called.
Destination	outputToStream() If the execution requires the generation of an intermediate file, the handler for ifNeedsFileOutput should be called
FilterConfig	pipeInto(FilterEngine nextFilter)
boolean	requiresFileOutput() Method yields true if the filter needs to create an intermediary output file
String	toString()

FilterExecutionJava

public FilterExecutionJava(Function<InputStream,InputStream> processor,
                           Destination source)

Method Detail

execStream

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

Ideally, premature closing of the input stream should propagate upstream and terminate any transformation processes upstream

Specified by:

execStream in interface FilterConfig

ifNeedsFileInput

public FilterConfig ifNeedsFileInput(Supplier<Path> pathRequester,
                                     BiConsumer<Path,FileWritingProcess> processCallback)

Same as execStream() as this execution engine will never ask for the creation of temporary files

Specified by:

ifNeedsFileInput in interface FilterConfig

Throws:

IOException

ifNeedsFileOutput

public FilterConfig ifNeedsFileOutput(Supplier<Path> pathRequester,
                                      BiConsumer<Path,FileWritingProcess> processCallback)

Specified by:

ifNeedsFileOutput in interface FilterConfig

pipeInto

public FilterConfig pipeInto(FilterEngine nextFilter)

Specified by:

pipeInto in interface FilterConfig

outputToFile

public DestinationFromFileCreation outputToFile(Path path)

Description copied from interface: FilterConfig

If explicit output to a file is requested, the handler set via ifNeedsFileOutput will not be called.

Specified by:

outputToFile in interface FilterConfig

Returns:

outputToStream

public Destination outputToStream()

Description copied from interface: FilterConfig

If the execution requires the generation of an intermediate file, the handler for ifNeedsFileOutput should be called

Specified by:

outputToStream in interface FilterConfig

Returns:

requiresFileOutput

public boolean requiresFileOutput()

Description copied from interface: FilterConfig

Method yields true if the filter needs to create an intermediary output file

Specified by:

requiresFileOutput in interface FilterConfig

Returns:

toString

public String toString()

Overrides:

toString in class Object
