Class MapValueResolver<K,V>

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.resolver.MapValueResolver<K,V>

Type Parameters:

K,V - the generic type for the items of the returned Map

All Implemented Interfaces:

ValueResolver<Map<K,V>>

public final class MapValueResolver<K,V>
extends Object
implements ValueResolver<Map<K,V>>

A ValueResolver that takes a list of ValueResolvers and upon invocation of resolve(Event) it return a Map 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

MapValueResolver

public MapValueResolver(Class<? extends Map> mapType,
                        List<ValueResolver<K>> keyResolvers,
                        List<ValueResolver<V>> valueResolvers)

Creates a new instance

Parameters:

mapType - the Class for a concrete Map type with a default constructor

keyResolvers - a not null List of resolvers for map key params

valueResolvers - a not null List of resolvers for map value params

Method Detail

of

public static <K,V> MapValueResolver<K,V> of(Class<? extends Map> mapType,
                                             List<ValueResolver<K>> keyResolvers,
                                             List<ValueResolver<V>> valueResolvers)

resolve

public Map<K,V> resolve(Event event)
                 throws org.mule.runtime.api.exception.MuleException

Passes the given event to each resolvers and outputs a map of type mapType with each result

Specified by:

resolve in interface ValueResolver<Map<K,V>>

Parameters:

event - a Event the event to evaluate

Returns:

a Map of type mapType

Throws:

org.mule.runtime.api.exception.MuleException

isDynamic

public boolean isDynamic()

Description copied from interface: ValueResolver

returns false if subsequent invocations to ValueResolver.resolve(Event) 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<Map<K,V>>

Returns:

true if at least one of the resolvers are dynamic
