Class ExtensionModelServiceCache

java.lang.Object

org.mule.tooling.client.internal.ExtensionModelServiceCache

All Implemented Interfaces:

org.mule.tooling.client.api.Disposable

public class ExtensionModelServiceCache
extends Object
implements org.mule.tooling.client.api.Disposable

In memory cache for ExtensionModels. Supports mule-plugin release and snapshot artifacts. It can be enabled to persist the value into disk. This can be done by setting a system property TOOLING_CLIENT_EXTENSION_MODEL_SERVICE_CACHE_DISKSTORE_PATH to define the path were data will be stored.
The support for SNAPSHOTS is based on the fimestamped version of artifacts (when downloaded from remote repositories) or the File.lastModified() value for SNAPSHOTS locally installed. Whenever a new snapshot version is discovered any previous version, if it was written into disk, will be removed and invalidated from the memory cache.

Method Detail

loadExtensionInformation

public Optional<LoadedExtensionInformation> loadExtensionInformation(org.mule.maven.client.api.model.BundleDependency bundleDependency,
                                                                     InternalExtensionModelService extensionModelService)

Loads an extension model from a ArtifactDescriptor.

It uses a cache, so it will only call the extensionModelService if there's a cache miss.

Parameters:

bundleDependency - the plugin BundleDependency

extensionModelService - the service to use to load the ExtensionModel in case of a cache miss

Returns:

the LoadedExtensionInformation, empty if the plugin does not have an extension model

loadExtensionModels

public Set<org.mule.runtime.api.meta.model.ExtensionModel> loadExtensionModels(List<org.mule.runtime.module.artifact.api.classloader.ArtifactClassLoader> artifactPluginClassLoaders,
                                                                               InternalExtensionModelService extensionModelService)

Loads the set of extension models from the list of ArtifactClassLoaders.

It uses a cache, so it will only call the extensionModelService if there's a cache miss.

Parameters:

artifactPluginClassLoaders - the list of plugin ArtifactClassLoader

extensionModelService - the service to use to load the ExtensionModel in case of a cache miss

Returns:

a Set of LoadedExtensionInformation, empty if none of the plugins have an extension model

loadExtensionInformation

public Optional<LoadedExtensionInformation> loadExtensionInformation(File plugin,
                                                                     InternalExtensionModelService extensionModelService)

Loads an extension model from a File pointing to the plugin artifact.

It uses a cache, so it will only call the extensionModelService if there's a cache miss.

Parameters:

plugin - the plugin descriptor

extensionModelService - the service to use to load the ExtensionModel in case of a cache miss

Returns:

the LoadedExtensionInformation, empty if the plugin does not have an extension model

loadRuntimeExtensionModels

public List<org.mule.runtime.api.meta.model.ExtensionModel> loadRuntimeExtensionModels(InternalExtensionModelService extensionModelService)

Loads the core extension model.

Parameters:

extensionModelService - the service to use to load the ExtensionModel in case of a cache miss

Returns:

the core extension model

dispose

public void dispose()

Specified by:
