Examples with RegionClassLoader org.mule.runtime.module.artifact.api.classloader.RegionClassLoader used on opensource projects

Example 1 with RegionClassLoader

use of org.mule.runtime.module.artifact.api.classloader.RegionClassLoader in project mule by mulesoft.

the class AbstractToolingClassLoaderTestCase method createAppClassLoader.

use of org.mule.runtime.module.artifact.api.classloader.RegionClassLoader in project mule by mulesoft.

the class ToolingApplicationClassLoaderBuilder method build.
