org.mule.runtime.module.extension.internal.value.ValueProviderMediator<T>

public final class ValueProviderMediator<T extends org.mule.runtime.api.meta.model.parameter.ParameterizedModel & org.mule.runtime.api.meta.model.EnrichableModel>
extends Object

Resolves a parameter's values by coordinating the several moving parts that are affected by the Value fetching process, so that such pieces can remain decoupled.

Constructor Detail

ValueProviderMediator

public ValueProviderMediator(T containerModel,
                             Supplier<MuleContext> muleContext)

Creates a new instance of the mediator

Parameters:

containerModel - container model which is a ParameterizedModel and EnrichableModel

muleContext - context to be able to initialize ValueProvider if necessary

Method Detail

getValues

public Set<org.mule.runtime.api.value.Value> getValues(String parameterName,
                                                       ParameterValueResolver parameterValueResolver)
                                                throws org.mule.runtime.extension.api.values.ValueResolvingException

Given the name of a parameter or parameter group, and if the parameter supports it, this will try to resolve the values for the parameter.

Parameters:

parameterName - the name of the parameter to resolve their possible values

parameterValueResolver - parameter resolver required if the associated ValueProvider requires the value of parameters from the same parameter container.

Returns:

a Set of Value correspondent to the given parameter

Throws:

org.mule.runtime.extension.api.values.ValueResolvingException - if an error occurs resolving values

getValues

public Set<org.mule.runtime.api.value.Value> getValues(String parameterName,
                                                       ParameterValueResolver parameterValueResolver,
                                                       Supplier<Object> connectionSupplier,
                                                       Supplier<Object> configurationSupplier)
                                                throws org.mule.runtime.extension.api.values.ValueResolvingException

Given the name of a parameter or parameter group, and if the parameter supports it, this will try to resolve the values for the parameter.

Parameters:

parameterName - the name of the parameter to resolve their possible values

parameterValueResolver - parameter resolver required if the associated ValueProvider requires the value of parameters from the same parameter container.

connectionSupplier - supplier of connection instances related to the container and used, if necessary, by the ValueProvider

configurationSupplier - supplier of connection instances related to the container and used, if necessary, by the ValueProvider

Returns:

a Set of Value correspondent to the given parameter

Throws:

org.mule.runtime.extension.api.values.ValueResolvingException - if an error occurs resolving values
