Constructor Detail

DomainClassLoaderBuilder

public DomainClassLoaderBuilder(ArtifactClassLoader parentClassLoader,
                                DeployableArtifactClassLoaderFactory<DomainDescriptor> artifactClassLoaderFactory,
                                RegionPluginClassLoadersFactory pluginClassLoadersFactory)

Creates a new builder for creating Domain artifacts.

Parameters:

parentClassLoader - classloader that will be the parent of the created classloaders. Non null

artifactClassLoaderFactory - factory for the classloader specific to the artifact resource and classes

pluginClassLoadersFactory - creates the class loaders for the plugins included in the domain's region. Non null

Method Detail

build

public MuleDeployableArtifactClassLoader build()
                                        throws IOException

Creates a new ArtifactClassLoader using the provided configuration. It will create the proper class loader hierarchy and filters so domain classes, resources and plugins are resolve correctly.

Overrides:

build in class AbstractArtifactClassLoaderBuilder<DomainClassLoaderBuilder>

Returns:

a MuleDeployableArtifactClassLoader created from the provided configuration.

Throws:

IOException - exception cause when it was not possible to access the file provided as dependencies

createArtifactClassLoader

protected ArtifactClassLoader createArtifactClassLoader(String artifactId,
                                                        RegionClassLoader regionClassLoader)

Description copied from class: AbstractArtifactClassLoaderBuilder

Creates the class loader for the artifact being built.

Specified by:

createArtifactClassLoader in class AbstractArtifactClassLoaderBuilder<DomainClassLoaderBuilder>

Parameters:

artifactId - identifies the artifact being created. Non empty.

regionClassLoader - class loader containing the artifact and dependant class loaders. Non null.

Returns:

getArtifactId

protected String getArtifactId(ArtifactDescriptor artifactDescriptor)

Specified by:

getArtifactId in class AbstractArtifactClassLoaderBuilder<DomainClassLoaderBuilder>

getParentClassLoader

protected ArtifactClassLoader getParentClassLoader()

Implementation must redefine this method and it should provide the root class loader which is going to be used as parent class loader for every other class loader created by this builder.

Specified by:

getParentClassLoader in class AbstractArtifactClassLoaderBuilder<DomainClassLoaderBuilder>

Returns:

the root class loader for all other class loaders

getDomainId

public static String getDomainId(String domainName)

Parameters:

domainName - name of the domain. Non empty.

Returns:

the unique identifier for the domain in the container.
