Class ResolverSet

java.lang.Object

org.mule.runtime.module.extension.internal.runtime.resolver.ResolverSet

All Implemented Interfaces:

org.mule.runtime.api.lifecycle.Initialisable, ValueResolver<ResolverSetResult>

Direct Known Subclasses:

HashedResolverSet

public class ResolverSet
extends Object
implements ValueResolver<ResolverSetResult>, org.mule.runtime.api.lifecycle.Initialisable

A ValueResolver which is based on associating a set of keys -> ValueResolver pairs. The result of evaluating this resolver is a ResolverSetResult.

The general purpose of this class is to repeatedly evaluate a set of ValueResolvers which results are to be used in the construction of an object, so that the structure of such can be described only once (by the set of keys and ValueResolvers but evaluated many times. With this goal in mind is that the return value of this resolver will always be a ResolverSetResult which then can be used by a ObjectBuilder to generate an actual object.

Instances of this class are to be considered thread safe and reusable

3.7.0

Method Detail

add

public ResolverSet add(String key,
                       ValueResolver resolver)

Links the given ValueResolver to the given ParameterModel. If such parameter was already added, then the associated resolver is replaced.

Parameters:

key - a not null ParameterModel

resolver - a not null ValueResolver

Returns:

this resolver set to allow chaining

Throws:

IllegalArgumentException - is either parameter or resolver are null

isDynamic

public boolean isDynamic()

Whether at least one of the given ValueResolver are dynamic

Specified by:

isDynamic in interface ValueResolver<ResolverSetResult>

Returns:

true if at least one resolver is dynamic. false otherwise

resolve

public ResolverSetResult resolve(ValueResolvingContext context)
                          throws org.mule.runtime.api.exception.MuleException

Evaluates all the added ValueResolvers and returns the results into a ResolverSetResult

Specified by:

resolve in interface ValueResolver<ResolverSetResult>

Parameters:

context - a not null ValueResolvingContext

Returns:

a ResolverSetResult

Throws:

org.mule.runtime.api.exception.MuleException - if an error occurs creating the ResolverSetResult

getResolvers

public Map<String,ValueResolver> getResolvers()

initialise

public void initialise()

Specified by:

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