DescribedObject, EnrichableModel, HasDisplayModel, HasLayoutModel, NamedObject, Typed

public interface ParameterModel
extends NamedObject, DescribedObject, EnrichableModel, Typed, HasDisplayModel, HasLayoutModel

A parameter of a Component or Configuration

A parameter provides a name, a type and a default value.

It can apply either to a ConfigurationModel or a ComponentModel

Method Detail

isRequired

boolean isRequired()

Whether or not this parameter is required. This method is exclusive with getDefaultValue() in the sense that a required parameter cannot have a default value. At the same time, if the parameter has a default value, then it makes no sense to consider it as required

Returns:

a boolean value saying if this parameter is required or not

isOverrideFromConfig

boolean isOverrideFromConfig()

Whether or not this parameter is bound to a ParameterModel of the same name and type that exists in the config associated to the container of this parameter.
When true, the parameter will be injected with the same value of the bound parameter of the config that's been associated to the execution.

Returns:

a boolean value saying if this parameter acts as an override for a parameter defined in a config.

getExpressionSupport

ExpressionSupport getExpressionSupport()

The level of support this parameter has for expressions

Returns:

a ExpressionSupport

getDefaultValue

Object getDefaultValue()

The default value for this parameter. It might be an expression if getExpressionSupport() returns ExpressionSupport.REQUIRED or ExpressionSupport.SUPPORTED.

This method is exclusive with isRequired(). Check that method's comments for more information on the semantics of this two methods.

Returns:

the default value

getDslConfiguration

ParameterDslConfiguration getDslConfiguration()

Returns:

A ParameterDslConfigurationwhich describes the language which allows configuring this parameter

getRole

ParameterRole getRole()

Returns:

this ParameterModel's role

getLayoutModel

Optional<LayoutModel> getLayoutModel()

The value of LayoutModel.getOrder() is to be consider relative to the owning ParameterGroupModel

Specified by:

getLayoutModel in interface HasLayoutModel

Returns:

An Optional LayoutModel which contains directives about how this parameter should be shown in the UI

getAllowedStereotypes

List<StereotypeModel> getAllowedStereotypes()

Returns:

a List of StereotypeModels that this ParameterModel should accept values of.

getValueProviderModel

Optional<ValueProviderModel> getValueProviderModel()

Returns:

A ValueProviderModel to communicate if the this parameter model is capable to provide values. an Optional.empty() if there is no model associate to this parameter.
