Method Detail

getContext

public static Context getContext()

Gets the Context singleton.

By default this class will instantiate a new context and hold it in a static class variable as the singleton to return for other calls. This behaviour can be changed by setting a system property with key org.jdtaus.core.container.ContextFactory to the name of a class defining a public static Context getContext() method returning the singleton instance of Context.

Returns:

the singleton Context instance.

Throws:

ContextError - for unrecoverable context errors.

newContext()

newContext

public static Context newContext()

Creates a new instance of the configured Context implementation.

The context implementation to be used can be controlled via a system property with key org.jdtaus.core.container.Context set to a class name to be loaded as the context implementation.

This method should be used by getContext() implementors to retrieve a new Context instance.

Returns:

a new instance of the configured Context implementation.

Throws:

ContextError - for unrecoverable context errors.
