Class Session

java.lang.Object
  org.netbeans.api.debugger.Session

public final class Session
extends Object
extends Object

Session visually represents one process or application. It should be simple bean with properties like process ID, session name, etc. All other functionality is deleagted to current debugger engine.

Description
Functionality Properties: Session has two standard read only properties - name (getName()) and location name (getLocationName()).

Management of languages and engines: Debugger Core supports debugging in different languages. It means that each session can be debugged using different languages and DebuggerEngines. Session manages list of supported languages (getSupportedLanguages()) and current language (getCurrentLanguage()). Current language can be changed (setCurrentLanguage(java.lang.String)). Each language corresponds to one DebuggerEngine (getEngineForLanguage(java.lang.String)). So, the current language defines current debuggger engine (getCurrentEngine()) A support for a new debugger language can be added during a start of debugging only. See DebuggerManager.startDebugging(org.netbeans.api.debugger.DebuggerInfo) and DebuggerEngineProvider

Support for aditional services: Session is final class. The standard method how to extend its functionality is using lookup methods (lookup and lookupFirst(java.lang.String, java.lang.Class)). There are two ways how to register some service provider for some type of Session:

Register 'live' instance of service provider during creation of new instance of Session (see method SessionProvider.getServices()).

Register service provider in Manifest-inf/debugger/<type ID> folder. See Debugger SPI for more information about registration.

Support for listening: Session propagates all changes to PropertyChangeListener.

Clinents / Providers This class is final, so it does not have any external provider. Debugger Core and UI modules are clients of this class.

Lifecycle A new instance of Session class can be created and registerred to DebuggerManager during the process of starting of debugging (see DebuggerManager.startDebugging(org.netbeans.api.debugger.DebuggerInfo)). Session is removed automatically from DebuggerManager when the number of "supported languages" (getSupportedLanguages()) is zero.
Evolution No method should be removed from this class, but some functionality can be added in future.

Description
Functionality	Properties: Session has two standard read only properties - name (`getName()`) and location name (`getLocationName()`). Management of languages and engines: Debugger Core supports debugging in different languages. It means that each session can be debugged using different languages and `DebuggerEngine`s. Session manages list of supported languages (`getSupportedLanguages()`) and current language (`getCurrentLanguage()`). Current language can be changed (`setCurrentLanguage(java.lang.String)`). Each language corresponds to one `DebuggerEngine` (`getEngineForLanguage(java.lang.String)`).
