Constructor Detail

PolicyTemplateClassLoaderBuilder

public PolicyTemplateClassLoaderBuilder(DeployableArtifactClassLoaderFactory artifactClassLoaderFactory,
                                        RegionPluginClassLoadersFactory pluginClassLoadersFactory)

Creates an AbstractArtifactClassLoaderBuilder.

Parameters:

artifactClassLoaderFactory - factory for the classloader specific to the artifact resource and classes. Must be not null.

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

Method Detail

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<PolicyTemplateClassLoaderBuilder>

Parameters:

artifactId - identifies the artifact being created. Non empty.

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

Returns:

getParentClassLoader

protected ArtifactClassLoader getParentClassLoader()

Description copied from class: AbstractArtifactClassLoaderBuilder

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<PolicyTemplateClassLoaderBuilder>

Returns:

the root class loader for all other class loaders

build

public MuleDeployableArtifactClassLoader build()
                                        throws IOException

Description copied from class: AbstractArtifactClassLoaderBuilder

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

Overrides:

build in class AbstractArtifactClassLoaderBuilder<PolicyTemplateClassLoaderBuilder>

Returns:

a ArtifactClassLoader created from the provided configuration.

Throws:

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

setParentClassLoader

public PolicyTemplateClassLoaderBuilder setParentClassLoader(ArtifactClassLoader parentClassLoader)

getArtifactId

protected String getArtifactId(ArtifactDescriptor artifactDescriptor)

Specified by:

getArtifactId in class AbstractArtifactClassLoaderBuilder<PolicyTemplateClassLoaderBuilder>

getPolicyId

public String getPolicyId(String policyName)
