Method Summary

Modifier and Type	Method	Description
ICombinedContext	getContext(int id)	Gets the context with the specified ID.
Map<URI,ArrayList<ICombinedContext>>	getContexts()	Lists all contexts keyed by the URI from which they were derived.
boolean	hasChanged()	A number of internal operations which could affect the list of currently open and available contexts happen in an unlinked or asynchronous manner.
boolean	hasMultipleContexts()	Convenience method for determining if more than one context is currently open.
void	removeAllContexts()	Close and remove all contexts from this manager.
void	removeContexts(Image image)	Remove all contexts which have been derived from an image source.
void	removeContexts(URI source)	Remove all contexts which have been defined as coming from a specified URI (note that the URI may or may not be a file URI).

Method Details

removeContexts

void removeContexts(Image image)

Remove all contexts which have been derived from an image source. e.g. if there are multiple JVMs in a single core then closing the core file would result in all images derived from that file also being closed.

Parameters:

image - the source image from which derived contexts should be closed.

removeContexts

void removeContexts(URI source)

Remove all contexts which have been defined as coming from a specified URI (note that the URI may or may not be a file URI).

Parameters:

URI - the source URI from which derived contexts should be closed.

removeAllContexts

void removeAllContexts()

Close and remove all contexts from this manager.

getContexts

Map<URI,ArrayList<ICombinedContext>> getContexts()

Lists all contexts keyed by the URI from which they were derived.

Returns:

map of URI's to contexts

hasMultipleContexts

boolean hasMultipleContexts()

Convenience method for determining if more than one context is currently open. It is a less expensive call than getContexts()

Returns:

true if more than one context is currently open and available

getContext

ICombinedContext getContext(int id)

Gets the context with the specified ID.

Parameters:

id - the context ID

Returns:

the located context or null if it was not found

hasChanged

boolean hasChanged()

A number of internal operations which could affect the list of currently open and available contexts happen in an unlinked or asynchronous manner. By calling this method the session (or external clients) are able to tell if the list of contexts has changed and anything related to this such as a display may need to be update.

Returns:
