Object allocation

These functions enable users to allocate new objects from within a user primitive.

EsObject EsAllocateObject(EsVMContext vmContext, EsBehavior allocateClass, U_32 size, U_32 saves, EsObject ** saveList)

Returns a new, initialized object of class allocateClass with size indexable instance variables. Pass 0 for saves and NULL for saveList. The instance variables of pointer objects are initialized to nil. All other objects are initialized to 0.

Error cases: If the object could not be allocated for any reason, returns NULL.

Smalltalk equivalent: allocateClass new: size

Side effects: This operation can cause a garbage collection.

EsObject EsAllocateArray(EsVMContext vmContext, U_32 size)

Returns a new, initialized Array object with size indexable instance variables. This is a convenience macro wrapping EsAllocateObject.

EsObject EsAllocateByteArray(EsVMContext vmContext, U_32 size)

Returns a new, initialized ByteArray object with size indexable instance variables. This is a convenience macro wrapping EsAllocateObject.

EsObject EsAllocateDBString(EsVMContext vmContext, U_32 size)

Returns a new, initialized DbString object with size indexable instance variables. This is a convenience macro wrapping EsAllocateObject.

EsObject EsAllocateString(EsVMContext vmContext, U_32 size)

Returns a new, initialized String object with size indexable instance variables. This is a convenience macro wrapping EsAllocateObject.

EsObject EsAllocateFixedObject(EsVMContext vmContext, EsBehavior allocateClass, U_32 size, U_32 saves, EsObject ** saveList)

Same as EsAllocateObject, except the object is allocated in fixed space. This means that the object does not move during a garbage collect.

Error cases: If the object could not be allocated for any reason, returns NULL.

Smalltalk equivalent: (allocateClass new: size) makeFixed
