Smalltalk current createPackage: 'Kernel-Classes' properties: #{}! Object subclass: #Behavior instanceVariableNames: '' package: 'Kernel-Classes'! !Behavior commentStamp! Behavior is the superclass of all class objects. It defines the protocol for creating instances of a class with `#basicNew` and `#new` (see `boot.js` for class constructors details). Instances know about the subclass/superclass relationships between classes, contain the description that instances are created from, and hold the method dictionary that's associated with each class. Behavior also provides methods for compiling methods, examining the method dictionary, and iterating over the class hierarchy.! !Behavior methodsFor: 'accessing'! allInstanceVariableNames | result | result := self instanceVariableNames copy. self superclass ifNotNil: [ result addAll: self superclass allInstanceVariableNames]. ^result ! allSubclasses | result | result := self subclasses. self subclasses do: [:each | result addAll: each allSubclasses]. ^result ! comment ^(self basicAt: 'comment') ifNil: [''] ! comment: aString self basicAt: 'comment' put: aString ! commentStamp ^ClassCommentReader new class: self; yourself ! commentStamp: aStamp prior: prior ^self commentStamp ! instanceVariableNames ! methodAt: aString ! methodDictionary ! methodsFor: aString ^ClassCategoryReader new class: self category: aString; yourself ! methodsFor: aString stamp: aStamp "Added for compatibility, right now ignores stamp." ^self methodsFor: aString ! name ! protocols | protocols | protocols := Array new. self methodDictionary do: [:each | (protocols includes: each category) ifFalse: [ protocols add: each category]]. ^protocols sort ! protocolsDo: aBlock "Execute aBlock for each method category with its collection of methods in the sort order of category name." | methodsByCategory | methodsByCategory := HashedCollection new. self methodDictionary values do: [:m | (methodsByCategory at: m category ifAbsentPut: [Array new]) add: m]. self protocols do: [:category | aBlock value: category value: (methodsByCategory at: category)] ! prototype ! subclasses ! superclass ! withAllSubclasses ^(Array with: self) addAll: self allSubclasses; yourself ! ! !Behavior methodsFor: 'compiling'! addCompiledMethod: aMethod ! compile: aString self compile: aString category: '' ! compile: aString category: anotherString Compiler new install: aString forClass: self category: anotherString; setupClass: self ! removeCompiledMethod: aMethod ! ! !Behavior methodsFor: 'instance creation'! basicNew ! new ^self basicNew initialize ! ! !Behavior methodsFor: 'testing'! canUnderstand: aSelector ^(self methodDictionary keys includes: aSelector asString) or: [ self superclass notNil and: [self superclass canUnderstand: aSelector]] ! inheritsFrom: aClass ^aClass allSubclasses includes: self ! !
