public < T > Object getBeanKey ( Contextual < T > bean ) { if ( passivationCapable ) { // if the return ( ( PassivationCapable ) bean ) . getId ( ) ; } return bean ; }

If the context is a passivating scope then we return the passivationId of the Bean . Otherwise we use the Bean directly .

public Contextual < ? > getBean ( Object beanKey ) { if ( passivationCapable ) { return beanManager . getPassivationCapableBean ( ( String ) beanKey ) ; } else { return ( Contextual < ? > ) beanKey ; } }

Restores the Bean from its beanKey .

Processes registered ManagedService and updates each with their own configuration properties .

Creates a LogRecord using any available input parameters from the various Logger methods .

private WsLogRecord createWsLogRecord ( Level level , String msg , Object [ ] params , String sourceClassName , String sourceMethodName , String resourceBundleName , ResourceBundle resourceBundle , Throwable thrown ) { WsLogRecord logRecord = new WsLogRecord ( level , msg ) ; if ( params != null ) { logRecord . setParameters ( params ) ; // special handling for byte arrays in the first param position if ( ( params . length > 0 && params [ 0 ] != null ) && byte . class . equals ( params [ 0 ] . getClass ( ) . getComponentType ( ) ) ) logRecord . setRawData ( ( byte [ ] ) params [ 0 ] ) ; } if ( sourceClassName != null ) { logRecord . setSourceClassName ( sourceClassName ) ; } if ( sourceMethodName != null ) { logRecord . setSourceMethodName ( sourceMethodName ) ; } if ( resourceBundleName != null ) { logRecord . setResourceBundleName ( resourceBundleName ) ; } if ( resourceBundle != null ) { logRecord . setResourceBundle ( resourceBundle ) ; } if ( thrown != null ) { logRecord . setThrown ( thrown ) ; } if ( getName ( ) != null ) { logRecord . setLoggerName ( getName ( ) ) ; } if ( getOrganization ( ) != null ) { logRecord . setOrganization ( getOrganization ( ) ) ; } if ( getProduct ( ) != null ) { logRecord . setProduct ( getProduct ( ) ) ; } if ( getComponent ( ) != null ) { logRecord . setComponent ( getComponent ( ) ) ; } LogRecordContext . getExtensions ( logRecord . getExtensions ( ) ) ; logRecord . setTraceClass ( ivTC . getTraceClass ( ) ) ; // populate runtime data // Note: this is WAS version, UOW, process ID, etc // WsLoggerRuntimeData.getInstance().populate(logRecord); return logRecord ; }

Construct a WsLogRecord with the given level and message values .

private String computeResourceBundleName ( ) { Logger logger = this ; while ( logger != null ) { String name = logger . getResourceBundleName ( ) ; if ( name != null ) { return name ; } logger = logger . getParent ( ) ; } return null ; }

Worker method to determine the resource bundle name to use for logger . If set this is just the resource bundle name of this logger . If not set move up through the list of parents and find the first non - null resource bundle name .

Introspect the object via reflection

private void addNewChild ( String name , Object value ) { IntrospectionLevelMember prospectiveMember = new IntrospectionLevelMember ( _level + 1 , name , makeDescription ( value ) , makeMember ( value ) , _allKnownMembersInThisTree ) ; if ( makeMember ( value ) != null ) { // OK, we'd like to introspect the object further - have we seen it? if ( _allKnownMembersInThisTree . contains ( prospectiveMember ) ) { // Already seen it, so ensure we don't reexamine it prospectiveMember = new IntrospectionLevelMember ( _level + 1 , name , makeDescription ( value ) , null , _allKnownMembersInThisTree ) ; } else { // Ensure we don't reexamine it if we see it again! _allKnownMembersInThisTree . add ( prospectiveMember ) ; } } _children . add ( prospectiveMember ) ; }

Add a new IntrospectionLevelMember to _children List ( Checking to see if the new child should be introspected further

private Object getFieldValue ( final Field field ) { Object field_value = AccessController . doPrivileged ( new PrivilegedAction < Object > ( ) { @ Override public Object run ( ) { try { Object value = field . get ( _member ) ; // Don't dump sensitive data boolean sensitive = _member . getClass ( ) . isAnnotationPresent ( Sensitive . class ) || field . isAnnotationPresent ( Sensitive . class ) ; if ( value != null && sensitive ) { value = DataFormatHelper . sensitiveToString ( value ) ; } return value ; } catch ( IllegalAccessException e ) { // No FFDC code needed - we're in the middle of FFDC'ing! // Should not happen - if it does return a string :-) return "/* Could not access " + field . getName ( ) + " */" ; } } } ) ; return field_value ; }

Return the value of the member s field

private Field [ ] getFields ( final Class < ? > currentClass ) { final Field [ ] objectFields = AccessController . doPrivileged ( new PrivilegedAction < Field [ ] > ( ) { @ Override public Field [ ] run ( ) { try { Field [ ] tempObjectFields = currentClass . getDeclaredFields ( ) ; if ( tempObjectFields . length != 0 ) { AccessibleObject . setAccessible ( tempObjectFields , true ) ; } return tempObjectFields ; } catch ( Throwable t ) { // Introspection of field failed StringWriter sw = new StringWriter ( ) ; PrintWriter pw = new PrintWriter ( sw ) ; t . printStackTrace ( pw ) ; addNewChild ( "Failed to resolve fields for " + currentClass . getName ( ) , sw . toString ( ) ) ; } return new Field [ 0 ] ; } } ) ; return objectFields ; }

Return the fields in a particular class

private String makeDescription ( Object value ) { String answer ; // Not initialized, so the compiler tells if we miss a // case if ( value == null ) { answer = "null" ; } else if ( value instanceof String ) { answer = "\"" + value + "\"" ; } else { Class < ? > objClass = value . getClass ( ) ; if ( ( objClass == Boolean . class ) || ( objClass == Character . class ) || ( objClass == Byte . class ) || ( objClass == Short . class ) || ( objClass == Integer . class ) || ( objClass == Long . class ) || ( objClass == Float . class ) || ( objClass == Double . class ) ) { answer = value . toString ( ) ; } else if ( objClass . isArray ( ) ) { if ( objClass . getComponentType ( ) . isPrimitive ( ) ) { answer = convertSimpleArrayToString ( value ) ; } else { answer = objClass . getComponentType ( ) + "[" + Array . getLength ( value ) + "]" ; } } else { answer = value . getClass ( ) . toString ( ) + "@" + Integer . toHexString ( System . identityHashCode ( value ) ) ; } } return answer ; }

Make a string that describes this object

public void print ( IncidentStream is , int maxDepth ) { StringBuffer fullName = new StringBuffer ( ) ; for ( int i = 0 ; i < _level ; i ++ ) fullName . append ( " " ) ; fullName . append ( _name ) ; is . writeLine ( fullName . toString ( ) , _description ) ; if ( _level < maxDepth ) { List < IntrospectionLevelMember > children = getChildren ( ) ; for ( IntrospectionLevelMember ilm : children ) { ilm . print ( is , maxDepth ) ; } } }

Print this IntrospectionLevelMember to an incident stream

public static RecoveryDirector recoveryDirector ( ) throws InternalLogException { if ( tc . isEntryEnabled ( ) ) Tr . entry ( tc , "recoveryDirector" ) ; // If the recovery director is null its an error in JET if ( _recoveryDirector == null ) { final InternalLogException ile = new InternalLogException ( ) ; if ( tc . isEntryEnabled ( ) ) Tr . exit ( tc , "recoveryDirector" , ile ) ; throw ile ; } if ( tc . isEntryEnabled ( ) ) Tr . exit ( tc , "recoveryDirector" , _recoveryDirector ) ; return _recoveryDirector ; }

Returns the singleton instance of the RecoveryDirector class . This method uses reflection rather then a direct reference to the underlying class to avoid a cyclic build dependency .

public static RecoveryDirector createRecoveryDirector ( ) { if ( tc . isEntryEnabled ( ) ) Tr . entry ( tc , "createRecoveryDirector" ) ; _recoveryDirector = LibertyRecoveryDirectorImpl . instance ( ) ; if ( tc . isEntryEnabled ( ) ) Tr . exit ( tc , "createRecoveryDirector" , _recoveryDirector ) ; return _recoveryDirector ; }

Create a RecoveryDirector singleton
