Interface Container

All Known Implementing Classes:

ContainerImp

public interface Container

Containers provide with a way to execute user code within such runtime restrictions that are defined by the container policy itself.

Usually they would represent a sandbox environment with lesser freedom than currently running process has.
Opposite would be possible only if in the system wide policy Container code has been given greater permission set than currently running has.

All access in JVM is governed by java.lang.SecurityManagerjava.security.Policy.
Containers execute the user code in a permission set defined by ContainerFactory. Factories itself could provide these definitions in adhoc manner and without a need to alter the system wide policy. created on Jun 9, 2005
