Classes hold on an instance of me; it is called their `environment'. 1.2.1 AbstractNamespace class: instance creation new Disabled - use #new to create instances primNew: parent name: spaceName Private - Create a new namespace with the given name and parent, and add to the parent a key that references it. 1.2.2 AbstractNamespace: accessing allAssociations Answer a Dictionary with all of the associations in the receiver and each of its superspaces (duplicate keys are associated to the associations that are deeper in the namespace hierarchy) allBehaviorsDo: aBlock Evaluate aBlock once for each class and metaclass in the namespace. allClassObjectsDo: aBlock Evaluate aBlock once for each class and metaclass in the namespace. allClassesDo: aBlock Evaluate aBlock once for each class in the namespace. allMetaclassesDo: aBlock Evaluate aBlock once for each metaclass in the namespace. classAt: aKey Answer the value corrisponding to aKey if it is a class. Fail if either aKey is not found or it is associated to something different from a class. classAt: aKey ifAbsent: aBlock Answer the value corrisponding to aKey if it is a class. Evaluate aBlock and answer its result if either aKey is not found or it is associated to something different from a class. 1.2.3 AbstractNamespace: compiling addSharedPool: aDictionary Import the given bindings for classes compiled with me as environment. import: aDictionary Import the given bindings for classes compiled with me as environment. removeSharedPool: aDictionary Remove aDictionary from my list of direct pools. Chapter 1: Base classes 9 sharedPoolDictionaries Answer the shared pools (not names) imported for my classes. 1.2.4 AbstractNamespace: copying copyEmpty: newSize Answer an empty copy of the receiver whose size is newSize whileCurrentDo: aBlock Evaluate aBlock with the current namespace set to the receiver. Answer the result of the evaluation. 1.2.5 AbstractNamespace: namespace hierarchy addSubspace: aSymbol Create a namespace named aSymbol, add it to the receiver's subspaces, and answer it. allSubassociationsDo: aBlock Invokes aBlock once for every association in each of the receiver's subspaces. allSubspaces Answer the direct and indirect subspaces of the receiver in a Set allSubspacesDo: aBlock Invokes aBlock for all subspaces, both direct and indirect. allSuperspacesDo: aBlock Evaluate aBlock once for each of the receiver's superspaces includesClassNamed: aString Answer whether the receiver or any of its superspaces include the given class { note that this method (unlike #includesKey:) does not require aString to be interned and (unlike #includesGlobalNamed:) only returns true if the global is a class object. includesGlobalNamed: aString Answer whether the receiver or any of its superspaces include the given key { note that this method (unlike #includesKey:) does not require aString to be interned but (unlike #includesClassNamed:) returns true even if the global is not a class object. removeSubspace: aSymbol Remove my subspace named aSymbol from the hierarchy. selectSubspaces: aBlock Return a Set of subspaces of the receiver satisfying aBlock. selectSuperspaces: aBlock Return a Set of superspaces of the receiver satisfying aBlock. siblings Answer all the other children of the same namespace as the receiver. siblingsDo: aBlock Evaluate aBlock once for each of the other root namespaces, passing the names- pace as a parameter. 10 GNU Smalltalk Library Reference subspaces Answer the receiver's direct subspaces subspacesDo: aBlock Invokes aBlock for all direct subspaces. superspace Answer the receiver's superspace. superspace: aNamespace Set the superspace of the receiver to be 'aNamespace'. Also adds the receiver as a subspace of it. withAllSubspaces Answer a Set containing the receiver together with its direct and indirect sub- spaces withAllSubspacesDo: aBlock Invokes aBlock for the receiver and all subclasses, both direct and indirect. 1.2.6 AbstractNamespace: overrides for superspaces inheritedKeys Answer a Set of all the keys in the receiver and its superspaces set: key to: newValue Assign newValue to the variable named as specified by `key'. This method won't define a new variable; instead if the key is not found it will searchin superspaces and raising an error if the variable cannot be found in any of the superspaces. Answer newValue. set: key to: newValue ifAbsent: aBlock Assign newValue to the variable named as specified by `key'. This method won't define a new variable; instead if the key is not found it will searchin superspaces and evaluate aBlock if it is not found. Answer newValue. values Answer a Bag containing the values of the receiver 1.2.7 AbstractNamespace: printing name Answer the receiver's name name: aSymbol Change the receiver's name to aSymbol nameIn: aNamespace Answer Smalltalk code compiling to the receiver when the current namespace is aNamespace printOn: aStream Print a representation of the receiver storeOn: aStream Store Smalltalk code compiling to the receiver Chapter 1: Base classes 11 1.2.8 AbstractNamespace: testing isNamespace Answer `true'. isSmalltalk Answer `false'. 1.3 AlternativeObjectProxy Defined in namespace Smalltalk Superclass: DumperProxy Category: Streams-Files I am a proxy that uses the same ObjectDumper to store an object
