Class CollectionValueResolver<T>

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.resolver.CollectionValueResolver<T>

Type Parameters:

T - the generic type for the items of the returned Collection

All Implemented Interfaces:

org.mule.runtime.api.lifecycle.Initialisable, ValueResolver<Collection<T>>

public final class CollectionValueResolver<T>
extends Object
implements ValueResolver<Collection<T>>, org.mule.runtime.api.lifecycle.Initialisable

A ValueResolver that takes a list of ValueResolvers and upon invocation of resolve(ValueResolvingContext) it return a Collection of values with the outcome of each original resolver.

This class implements Lifecycle and propagates those events to each of the resolvers

Since:

3.7.0

Constructor Detail

CollectionValueResolver

public CollectionValueResolver(Class<? extends Collection> collectionType,
                               List<ValueResolver<T>> resolvers)

Creates a new instance

Parameters:

collectionType - the Class for a concrete Collection type with a default constructor

resolvers - a not null List of resolvers

Method Detail

of

public static <T> CollectionValueResolver<T> of(Class<? extends Collection> collectionType,
                                                List<ValueResolver<T>> resolvers)

resolve

public Collection<T> resolve(ValueResolvingContext context)
                      throws org.mule.runtime.api.exception.MuleException

Passes the given event to each resolvers and outputs a collection of type collectionType with each result

Specified by:

resolve in interface ValueResolver<Collection<T>>

Parameters:

context - a ValueResolvingContext the context used for evaluation

Returns:

a Collection of type collectionType

Throws:

org.mule.runtime.api.exception.MuleException

isDynamic

public boolean isDynamic()

Description copied from interface: ValueResolver

Returns false if subsequent invocations to ValueResolver.resolve(ValueResolvingContext) will return the same value. Notice that if it returns true, then it might return different values per invocation but that's not guaranteed.

Specified by:

isDynamic in interface ValueResolver<Collection<T>>

Returns:

true if at least one of the resolvers are dynamic

initialise

public void initialise()
                throws org.mule.runtime.api.lifecycle.InitialisationException

Specified by:

initialise in interface org.mule.runtime.api.lifecycle.Initialisable

Throws:

org.mule.runtime.api.lifecycle.InitialisationException
