Detailed Description

ML-Module base class to simplify development of modules encapsulating an algorithm with dedicated input and output interface.

The class AlgorithmModule already implements an update behavior and status feedback mechanism including a field interface. A developer of a derivative class has to declare module's input and output fields: The name of an input field has to start with prefix "in" followed by an uppercase letter. The name of an output field has to start with prefix "out" followed by an uppercase letter. Beside this the developer has to overwrite interface methods of base class:

  • to validate values of the input fields: validateInput(),
  • to update values of the output fields: update(),
  • to clear values of the output fields: clear(), and if the module owns output image field(s):
  • the interface method to set the properties of the output image(s): setOutputImageProperties().

◆ AlgorithmModule()

ml::AlgorithmModule::AlgorithmModule ( int numInputImages,
int numOutputImages )

Forwards given parameters to base class constructor.

Creates fields of update control and status feedback interface.

Parameters
numInputImagesNumber of input images.
numOutputImagesNumber of output images.

Member Function Documentation

◆ activateAttachments()

void ml::AlgorithmModule::activateAttachments ( )
overridevirtual

Never overwrite this method in derivative!

Updates the internal module state after loading or cloning the module, and enables notification handling again. Related to current value of field onInputChangeBehavior an update or clear is initiated.

Reimplemented from ml::FieldContainer.

◆ calculateOutputImageProperties()

void ml::AlgorithmModule::calculateOutputImageProperties ( int outputIndex,
PagedImage * outputImage )
overridevirtual

Never overwrite this method in derivative!

Makes sure to call derivative's implementation of setOutputImageProperties() only if update succeeded. Otherwise the output image is invalidated. Handles occurring AlgorithmModule::Error or invalidated output image as result of setOutputImageProperties() and sets status fields accordingly.

Parameters
outputIndexIndex of affected output image field.
outputImageAffected output image.

Reimplemented from ml::Module.

◆ clear()

virtual void ml::AlgorithmModule::clear ( )
protectedpure virtual

Clears the values of module's output fields (object and parameter fields).

Implemented in ml::DicomModifyTree, ml::AlgorithmModuleExample, and ml::AlgorithmModuleExampleWithOutputImage.

◆ handleNotification()

void ml::AlgorithmModule::handleNotification ( Field * field)
overridevirtual

Never overwrite this method in derivative!

Handles field changes. When affected field is identified as an input field than update or clear of module's output fields related to current value of field onInputChangeBehavior is initiated. Interface fields are also considered:

  • update: Initiates update.
  • clear: Initiates clear.
  • onInputChangeBehavior: Initiates update if value is "Update".
    Parameters
    fieldAffected field whose value was changed.

Reimplemented from ml::Module.

◆ setOutputImageProperties()

virtual void ml::AlgorithmModule::setOutputImageProperties ( int outputIndex,
PagedImage * outputImage )
protectedvirtual

Sets properties of the output image at output outputIndex.

Parameters
outputIndexIndex of affected output image field.
outputImageAffected output image.
Exceptions
Throwsan exception of type AlgorithmModule::Error on failure.

Reimplemented in ml::AlgorithmModuleExampleWithOutputImage.
