Constructor Detail

JIPipeAlgorithm

public JIPipeAlgorithm(JIPipeNodeInfo info,
                       JIPipeSlotConfiguration slotConfiguration)

Initializes a new node type instance and sets a custom slot configuration

Parameters:

info - The algorithm info

slotConfiguration - The slot configuration

JIPipeAlgorithm

public JIPipeAlgorithm(JIPipeNodeInfo info)

Initializes a new node type instance

Parameters:

info - The algorithm info

JIPipeAlgorithm

public JIPipeAlgorithm(JIPipeAlgorithm other)

Creates a copy

Parameters:

other - the original

Method Detail

run

public void run(JIPipeProgressInfo progressInfo)

Description copied from class: JIPipeGraphNode

Runs the workload

Specified by:

run in class JIPipeGraphNode

Parameters:

progressInfo - progress passed from the runner

reportValidity

public void reportValidity(JIPipeIssueReport report)

Description copied from interface: JIPipeValidatable

Generates a validity report

Parameters:

report - the report to be added to

runPassThrough

protected void runPassThrough(JIPipeProgressInfo progressInfo)

Runs the pass through. Override this for custom implementations if you want

Parameters:

progressInfo - the progress

canAutoPassThrough

protected boolean canAutoPassThrough()

Returns true if the algorithm can automatically apply pass-through This is only possible if there is at most one input and at most one output. Input must be compatible to the output.

Returns:

if the algorithm can automatically apply pass-through

canPassThrough

protected boolean canPassThrough()

Returns true if the algorithm can apply pass-through. Override this method to implement your own checks

Returns:

true if the algorithm can apply pass-through

isEnabled

public boolean isEnabled()

setEnabled

public void setEnabled(boolean enabled)

isPassThrough

public boolean isPassThrough()

setPassThrough

public void setPassThrough(boolean passThrough)

isParameterUIVisible

public boolean isParameterUIVisible(JIPipeParameterTree tree,
                                    JIPipeParameterAccess access)

Description copied from interface: JIPipeParameterCollection

Allows to override the visibility of parameters inside the UI

Specified by:

isParameterUIVisible in interface JIPipeParameterCollection

Overrides:

isParameterUIVisible in class JIPipeGraphNode

Parameters:

tree - the parameter tree that is used to access this parameter

access - the parameter

Returns:

if the parameter is visible inside the UI

getStateId

public String getStateId()

Returns a unique identifier that represents the state of the algorithm. Defaults to a JSON-serialized representation using the JIPipeAlgorithm.StateSerializer. Override this method if you have external influences.

Returns:

the state id

isPreprocessor

public boolean isPreprocessor()

Indicates if the node should be run before all other nodes. Only applies if there is no input. Defaults to false.

Returns:

If the node should behave like a preprocessor.

isPostprocessor

public boolean isPostprocessor()

Indicates if the node should be run after all other nodes. Only applies if the output is not used or there is no output. Defaults to false

Returns:

If the node should behave like a postprocessor.

getThreadPool

public JIPipeFixedThreadPool getThreadPool()

setThreadPool

public void setThreadPool(JIPipeFixedThreadPool threadPool)

Sets the thread pool. Depending on the implementation, the pool is just ignored.

Parameters:

threadPool - can be null (forces single-threaded run)

loadExample

public void loadExample(JIPipeNodeExample example)

Loads an example. Warning: This method will not ask for confirmation

Parameters:
