Field Details

customFunctionProviders

protected List<FeelCustomFunctionProvider> customFunctionProviders

A protected field that stores a list of custom function providers for the FEEL engine. Custom function providers are instances of FeelCustomFunctionProvider that define additional custom functions to be made available in FEEL expressions.

Constructor Details

ScalaFeelEngineFactory

public ScalaFeelEngineFactory()

Default constructor for the ScalaFeelEngineFactory. Initializes the factory with default settings and no custom function providers.

ScalaFeelEngineFactory

public ScalaFeelEngineFactory(List<FeelCustomFunctionProvider> customFunctionProviders)

Constructs a new instance of ScalaFeelEngineFactory with the given list of custom function providers. The custom function providers allow extending the FEEL engine by adding custom functions to FEEL expressions.

Parameters:

customFunctionProviders - a list of FeelCustomFunctionProvider that supply additional custom functions to be available in the FEEL engine.

Method Details

createInstance

public FeelEngine createInstance()

Creates a new instance of ScalaFeelEngine configured with the optional custom function providers. The instance provides an implementation of the FeelEngine interface for evaluating FEEL expressions.

Specified by:

createInstance in interface FeelEngineFactory

Returns:

a new instance of ScalaFeelEngine, which implements FeelEngine.

setCustomFunctionProviders

public void setCustomFunctionProviders(List<FeelCustomFunctionProvider> customFunctionProviders)

Sets the custom function providers for the engine factory. Custom function providers allow extending the FEEL engine with additional custom functions that can be used in FEEL expressions.

Parameters:

customFunctionProviders - a list of FeelCustomFunctionProvider instances, each defining custom functions for the FEEL engine.

getCustomFunctionProviders

public List<FeelCustomFunctionProvider> getCustomFunctionProviders()

Retrieves the list of custom function providers that have been configured for the factory. Custom function providers supply additional custom functions that can be used in FEEL expressions.

Returns:

a list of FeelCustomFunctionProvider instances, which define custom functions to extend the functionality of the FEEL engine.
