Constructor Detail

FileDataSource

public FileDataSource(JIPipeNodeInfo info)

Initializes the algorithm

Parameters:

info - The algorithm info

FileDataSource

public FileDataSource(FileDataSource other)

Copies the algorithm

Parameters:

other - The original

Method Detail

run

public void run(JIPipeGraphNodeRunContext runContext,
                JIPipeProgressInfo progressInfo)

Description copied from class: JIPipeGraphNode

Runs the workload

Overrides:

run in class JIPipeAlgorithm

Parameters:

runContext - the context of the run process

progressInfo - progress passed from the runner

getFileName

public Path getFileName()

Returns:

The file name

setFileName

public void setFileName(Path fileName)

Sets the file name

Parameters:

fileName - The file name

isNeedsToExist

public boolean isNeedsToExist()

setNeedsToExist

public void setNeedsToExist(boolean needsToExist)

getAbsoluteFileName

public Path getAbsoluteFileName()

Returns:

The file name as absolute path

archiveTo

public void archiveTo(JIPipeWriteDataStorage projectStorage,
                      JIPipeWriteDataStorage wrappedExternalStorage,
                      JIPipeProgressInfo progressInfo,
                      Path originalBaseDirectory)

Description copied from class: JIPipeGraphNode

Called when the node is being archived into the specified storage. The function is called on the copy of the node

Overrides:

archiveTo in class JIPipeGraphNode

Parameters:

projectStorage - the storage where the data will be archived. storage where the project itself is located.

wrappedExternalStorage - storage where wrapped external files are put

progressInfo - the progress info

originalBaseDirectory - current project directory

reportValidity

public void reportValidity(JIPipeValidationReportContext reportContext,
                           JIPipeValidationReport report)

Description copied from interface: JIPipeValidatable

Generates a validity report

Specified by:

reportValidity in interface JIPipeValidatable

Overrides:

reportValidity in class JIPipeAlgorithm

Parameters:

reportContext - the report context

report - the report to be added to

setBaseDirectory

public void setBaseDirectory(Path baseDirectory)

Description copied from class: JIPipeGraphNode

Sets the current work directory of this algorithm. This is used internally to allow loading data from relative paths. This triggers a JIPipeGraphNode.BaseDirectoryChangedEvent that can be received by JIPipeDataSlot instances to adapt to the work directory.

Overrides:

setBaseDirectory in class JIPipeGraphNode

Parameters:

baseDirectory - The work directory. Can be null
