Class MetadataMediator<T extends org.mule.runtime.api.meta.model.ComponentModel>

java.lang.Object

org.mule.runtime.module.extension.internal.metadata.MetadataMediator<T>

public final class MetadataMediator<T extends org.mule.runtime.api.meta.model.ComponentModel>
extends Object

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

This mediator will coordinate the resolvers: MetadataResolverFactory, TypeKeysResolver, InputTypeResolver and OutputTypeResolver, and the descriptors that represent their results: ComponentMetadataDescriptor, OutputMetadataDescriptor and TypeMetadataDescriptor

Since:

4.0

Method Detail

getMetadataKeys

public org.mule.runtime.api.metadata.resolving.MetadataResult<org.mule.runtime.api.metadata.MetadataKeysContainer> getMetadataKeys(org.mule.runtime.api.metadata.MetadataContext context,
                                                                                                                                   ReflectionCache reflectionCache)

Resolves the list of types available for the Content or Output of the associated MetadataKeyProvider Component, representing them as a list of MetadataKey.

If no MetadataKeyId is present in the component's input parameters, then a NullMetadataKey is returned. Otherwise, the TypeKeysResolver.getKeys(org.mule.runtime.api.metadata.MetadataContext) associated with the current Component will be invoked to obtain the keys

Parameters:

context - current MetadataContext that will be used by the TypeKeysResolver

Returns:

Successful MetadataResult if the keys are obtained without errors Failure MetadataResult when no Dynamic keys are a available or the retrieval fails for any reason

getMetadataKeys

public org.mule.runtime.api.metadata.resolving.MetadataResult<org.mule.runtime.api.metadata.MetadataKeysContainer> getMetadataKeys(org.mule.runtime.api.metadata.MetadataContext context,
                                                                                                                                   ParameterValueResolver metadataKeyResolver,
                                                                                                                                   ReflectionCache reflectionCache)

getMetadata

public org.mule.runtime.api.metadata.resolving.MetadataResult<org.mule.runtime.api.metadata.descriptor.ComponentMetadataDescriptor<T>> getMetadata(org.mule.runtime.api.metadata.MetadataContext context,
                                                                                                                                                   org.mule.runtime.api.metadata.MetadataKey key)

Resolves the ComponentMetadataDescriptor for the associated context using the specified key

Parameters:

context - current MetadataContext that will be used by the metadata resolvers.

key - MetadataKey of the type which's structure has to be resolved, used both for input and output types

Returns:

Successful MetadataResult if the MetadataTypes are resolved without errors Failure MetadataResult when the Metadata retrieval of any element fails for any reason

getMetadata

public org.mule.runtime.api.metadata.resolving.MetadataResult<org.mule.runtime.api.metadata.descriptor.ComponentMetadataDescriptor<T>> getMetadata(org.mule.runtime.api.metadata.MetadataContext context,
                                                                                                                                                   ParameterValueResolver metadataKeyResolver,
                                                                                                                                                   ReflectionCache reflectionCache)

Resolves the ComponentMetadataDescriptor for the associated context using the component ParameterValueResolver to resolve an object with the value of the MetadataKey.

Parameters:

context - current MetadataContext that will be used by the metadata resolvers.

Returns:

Successful MetadataResult if the MetadataTypes are resolved without errors Failure MetadataResult when the Metadata retrieval of any element fails for any reason
