Constructor Detail

AbstractDependentContextFactory

protected AbstractDependentContextFactory()
                                   throws ContextFactoryRegistrationError

Construct object of class AbstractDependentContextFactory.

Throws:

ContextFactoryRegistrationError - when the context factory is already registered with the context factory registry

Method Detail

setTypeUnsafeContext

public void setTypeUnsafeContext(java.lang.Object context)
                          throws java.lang.UnsupportedOperationException

Replace actual context with new one in stack of contexts. If no context is stored, this one will be added.

Parameters:

context - new actual context replacing the old one on the stack

Throws:

java.lang.UnsupportedOperationException - when the context factory isn't supporting this writing optional operation

removeTypeUnsafeContext

public void removeTypeUnsafeContext()
                             throws java.lang.UnsupportedOperationException

Remove actual context including all other stacked contexts completely (optional operation).

Throws:

java.lang.UnsupportedOperationException - when the context factory isn't supporting this writing optional operation

popTypeUnsafeContext

public java.lang.Object popTypeUnsafeContext()
                                      throws ContextUnavailableException,
                                             java.lang.UnsupportedOperationException

Get and remove actual context from the stack of contexts.

Returns:

last actual context on the context stack

Throws:

ContextUnavailableException - when no (more) context is available on the context stack

java.lang.UnsupportedOperationException - when the context factory isn't supporting this writing optional operation

pushTypeUnsafeContext

public void pushTypeUnsafeContext(java.lang.Object context)
                           throws java.lang.UnsupportedOperationException

Add new context to the top of the stack of contexts.

Parameters:

context - new actual context
