Class ExecContextFactoryHolder

java.lang.Object

org.azyva.dragom.execcontext.support.ExecContextFactoryHolder

public class ExecContextFactoryHolder
extends Object

Holds and provides access to an ExecContextFactory.

Allows generic tools to be provided by Dragom or other third party that can be integrated as a client tool by providing a way for client tools to easily provide the ExecContextFactory to use. Tools provided by Dragom make use of this strategy.

Dragom attempts to remain as independent as possible from external frameworks whose use would have impacts on clients, such as Spring. But at the same time Dragom must not prevent the use of such frameworks. This class allows, but does not force, the ExecContextFactory to be set using a dependency injection framework such as Spring.

ExecContextFactoryHolder can also be used by tools without using a dependency injection framework. The ExecContextFactory can simply be set by bootstrapping code before invoking the tool.

The ExecContextFactory is simply held in a static variable.

As a convenience, if no ExecContextFactory is set, the class identified by the org.azyva.dragom.DefaultExecContextFactory system property is used or DefaultExecContextFactory if not specified.

Util.applyDragomSystemProperties() is called during initialization of this class.
