Constructor Detail

PathDataSource

public PathDataSource(JIPipeNodeInfo info)

Initializes the algorithm

Parameters:

info - The algorithm info

PathDataSource

public PathDataSource(PathDataSource other)

Copies the algorithm

Parameters:

other - The original

Method Detail

run

public void run(JIPipeProgressInfo progressInfo)

Description copied from class: JIPipeGraphNode

Runs the workload

Overrides:

run in class JIPipeAlgorithm

Parameters:

progressInfo - progress passed from the runner

getPath

public Path getPath()

Returns:

The file name

setPath

public void setPath(Path path)

Sets the file name

Parameters:

path - The file name

isNeedsToExist

public boolean isNeedsToExist()

setNeedsToExist

public void setNeedsToExist(boolean needsToExist)

getAbsolutePath

public Path getAbsolutePath()

Returns:

The file name as absolute path

reportValidity

public void reportValidity(JIPipeIssueReport report)

Description copied from interface: JIPipeValidatable

Generates a validity report

Specified by:

reportValidity in interface JIPipeValidatable

Overrides:

reportValidity in class JIPipeAlgorithm

Parameters:

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
