Constructor Detail

ApplicationClassLoaderBuilder

public ApplicationClassLoaderBuilder(DeployableArtifactClassLoaderFactory<ApplicationDescriptor> artifactClassLoaderFactory,
                                     ArtifactPluginRepository artifactPluginRepository,
                                     ArtifactClassLoaderFactory<ArtifactPluginDescriptor> artifactPluginClassLoaderFactory,
                                     ArtifactDescriptorFactory<ArtifactPluginDescriptor> artifactDescriptorFactory,
                                     DependenciesProvider dependenciesProvider)

Creates a new builder for creating Application artifacts.

The domainRepository is used to locate the domain that this application belongs to and the artifactClassLoaderBuilder is used for building the common parts of artifacts.

Parameters:

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

artifactPluginRepository - repository of plugins contained by the runtime

artifactPluginClassLoaderFactory - creates artifact plugin class loaders.

artifactDescriptorFactory - factory to create ArtifactPluginDescriptor when there's a missing dependency to resolve

dependenciesProvider - resolver for missing dependencies.

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 application classes, resources, plugins and it's domain resources are resolve correctly.

Overrides:

build in class AbstractArtifactClassLoaderBuilder<ApplicationClassLoaderBuilder>

Returns:

a MuleDeployableArtifactClassLoader created from the provided configuration.

Throws:

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

getArtifactId

protected String getArtifactId(ArtifactDescriptor artifactDescriptor)

Specified by:

getArtifactId in class AbstractArtifactClassLoaderBuilder<ApplicationClassLoaderBuilder>

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<ApplicationClassLoaderBuilder>

Returns:

the root class loader for all other class loaders

setDomain

public ApplicationClassLoaderBuilder setDomain(Domain domain)

Parameters:

domain - the domain artifact to which the application that is going to use this classloader belongs.

Returns:

the builder

getApplicationId

public static String getApplicationId(String domainId,
                                      String applicationName)

Parameters:

domainId - name of the domain where the application is deployed. Non empty.

applicationName - name of the application. Non empty.

Returns:

the unique identifier for the application in the container.
