Object

SingleProcessFactory

AbstractFeatureCollectionProcessFactory

All Implemented Interfaces:

ProcessFactory, Factory, OptionalFactory

Direct Known Subclasses:

FeatureToFeatureProcessFactory

public abstract class AbstractFeatureCollectionProcessFactory
extends SingleProcessFactory

Base class for process factories which perform an operation on each feature in a feature collection.

Subclasses must implement:

• ProcessFactory.getTitle()
• ProcessFactory.getDescription(Name)
• addParameters(Map)

Since:

2.6

Method Details

getParameterInfo

public final Map<String,Parameter<?>> getParameterInfo()

Adds the FEATURES parameter and then delegates to addParameters(Map).

Specified by:

getParameterInfo in class SingleProcessFactory

addParameters

protected abstract void addParameters(Map<String,Parameter<?>> parameters)

Method for subclasses to add parameter descriptors for the process.

Subclasses should not add a parameter for the input feature collection as this is done by the case class. Example implementation for a simple buffer example:

 protected void addParameters(Map<String, Parameter<?>> parameters) {
    parameters.put(BUFFER.key, BUFFER);
 }
