MacApp 2.0 Object and Method Reference This chapter describes the object classes that existed in MacApp 1.1. If you need infonnation on classes and methods not described here. refer to other release notes and to the source code. Each object description in this chapter contains the following elements: • whether you customize the object type. instantiate it. or call its methods • notes about the object type • the chain of ancestors leading to the object type • field declarations and explanations • descriptions of the methods for each object type Important Complete Information about the Implementation of each method Is not given In this chapter. If you need further details ab6ut any method. refer to the MacApp source code. TObject Customize: usually Instantiate: never Call methods: usually TObject is the ultimate ancestor for all objects in MacApp. TObject is documented here primarily for background information. It is an abstract object type that exists so that other object types can inherit characteristics from it, and thus share them. The only TObject methods you might override are Free and Clone. Ancestors: none Fields none MacApp 2.0 Globals 10/3/88 Page 1 Clone FUNCTION TObject .Clone: TObject; The retum value An exact copy of the calling object Purpose To clone dependent objects referred to by the fields of an object as well as cloning the object i~lf. An object is dependent on another object when the second object has the only (or the only important) reference to the first object Dependency is a relatively vague condition; when you override this method, you need to detennine what objects are dependent on SELF. The default version Calls ShallowClone, and thus clones only the object i~lf Override Sometimes Call Sometimes Free PROCEDURE TOb ject:. Free; Purpose To free the calling object and any dependent objects referred to by its fields. An· object is dependent on another object when the second object has the only (or the only important) reference to the first object Dependency is a relatively vague condition; when you override this method, you need to determine what objects are dependent on SELF. Th• default version Calls ShallowFree Override Often. Your version should free any dependent objects you have added for your customization and then call INHERITED Free so that any ancestor methods can free other dependent objects. The chain of INHERI1ED calls leads to TObject.Free, which calls TObjecLShallowFree, which frees SELF. Call Often ShallowClone FUNCTION TObject.

The Standard Stot:age 'Manager Overview UnitBz p?,"ovides a client: with routines .to manage a piece of contiguous mem.ory,. called a heap zotie (hz).. ·rn the case of 'Lisa, :this is usually but not necessarily an MMU segment .. UnitB.z will mall&ge an arbitra.ry number Qf such zones-.. The zone. is: made up of a zone beader (aMJ followed by au arbittary number .Qf storage blocks (a:bk). The zone may be arbitrar.ily large. A storage block consists Qf a: header followed by usable memory. Blacks are ;t1ways of even: length within a specif.fed min.am and maximunt. The curren"t minim.um ts 12 bytelh the length ()f a m.±nimum f.ree block. This could be reduced to 4 bytes if desired by re¢oding portions of Unitiz. 'the aaxim\1111 size of an allocated block i:s currently J2K bytes. This could be increased to 65K bytes with mi.nor enhancements or to 231 bf ma.king the appropriate quaittitie.s a full 32 bits" There al:'e four types of storage. blocltih. relocatable and nam.ed. They are free, non-relocatahtet Free blocks are used by the implementation and not '1'isible to the c1ient. They are kep:t: on a doubly ibked list through fields in tbe free ·1110.ck header.. Free blocks maf be as large the entire. zone. Non.. relocatable blocks behave like objects. allocated on a Paeca.l he•P with NEW and DISPQS:X,. The user references a non-relocatable block through a pointet: to the first data byte~ · Relocatable blocks, as . the name suggests;, lil.ll.Y •be moved aroun.d in mem.ory (relocated)- when necessary. There are two prineipal advantages to using relocatabl.e blocks rather than non•relocatable bloclts. First, relocatable blocks can change size dynamieally. Second,. better utilization of available memory is possible vitb a zone of reloca.table blocks than non-relocatable bloclti!J because the storage m.anager 1 ~hen unable to find a free bll)ck l.ar.ge enough to satisfy an allocation request will move bl.oeks around t.o create a large enough free block. ln order to achieve this relGeatablility the user ref et:ences a relocatable bloek tb:tough a l'landle (h) which is a pointer to the pointer tc the first data byte. There is precisely one pointer to. the actu.al data, called t,he 111.aster pointer.. The handle points to it.. The storage manager remembers its location ~nd U.pdates it whenever the block is :teloeated. Thi.s uniqul!! po:Lni:er. is normally located in an array o~ po.inters at the end ol the zone header but the user may specify, at Z«>ne irtiti&lfaation the, precisely one <>tber block of menipry in wh:tch he wishes to alloea;te these ~aster po.inters. This atea is <• 32K bytes long.. .A pointe'l', once allocated in this area, l'IPlSt never move; so a maste; pointer cannot be allocated inside another ,relocatable object.
