kAssembly Class Reference

Description

Represents a library of types.

An assembly represents a collection of types. Typically, one assembly is defined per library or application.

The kAssembly_Enumerate method can be used to get a list of all loaded assemblies. The kAssemblyOf macro can be used to obtain a handle to a specific type assembly using the compile-time assembly symbol.

//prints a list of supplemental assemblies that have been constructed (i.e., assemblies other than kApiLib)
kStatus PrintOtherAssemblies()
{
kAssembly coreAssembly = kAssemblyOf(kApiLib);
kArrayList assemblyList = kNULL;
kSize i;
{
//get a list of the loaded assemblies
kTest(kArrayList_Construct(&assemblyList, kTypeOf(kAssembly), 0, kNULL));
kTest(kAssembly_Enumerate(assemblyList));
//print information for all assemblies except kApiLib
for (i = 0; i < kArrayList_Count(assemblyList); ++i)
{
kAssembly assembly = kArrayList_As_(assemblyList, i, kAssembly);
if (assembly != coreAssembly)
{
printf("%s (%u types)\n", kAssembly_Name(assembly), (k32u)kAssembly_TypeCount(assembly));
}
}
}
{
//dispose the list of assemblies; each assembly handle returned by kAssembly_Enumerate
//is a reference-counted instance that must be destroyed
kObject_Dispose(assemblyList);
}
return kOK;

Member Function Documentation

kStatus kAssembly_AddLoadHandler ( kCallbackFx  function,
kPointer  receiver 
)

Adds a callback to be notified when a new assembly is loaded.

The callback will be notified immediately after the assembly is loaded. The callback 'sender' argument will be the handle of the loaded assembly.

The static assembly lock (an internal, recursive, mutual exclusion structure) is held for the duration of callback invocation. Callback functions should be structured accordingly to avoid the potential for deadlock.

Parameters
functionCallback function.
receiverContext pointer for callback function.
Returns
Operation status.
kStatus kAssembly_AddUnloadedHandler ( kCallbackFx  function,
kPointer  receiver 
)

Adds a callback to be notified after unloading an assmebly.

The callback will be notified just after the release of the assembly's static types, and just prior to destroying the assembly handle. The callback 'sender' argument will be the handle of the assembly that is being unloaded.

The static assembly lock (an internal, recursive, mutual exclusion structure) is held for the duration of callback invocation. Callback functions should be structured accordingly to avoid the potential for deadlock.

Parameters
functionCallback function.
receiverContext pointer for callback function.
Returns
Operation status.
kStatus kAssembly_AddUnloadHandler ( kCallbackFx  function,
kPointer  receiver 
)

Adds a callback to be notified just prior to unloading an assembly.

The callback will be notified just prior to unloading the assembly. The callback 'sender' argument will be the handle of the assembly that is being unloaded.

The static assembly lock (an internal, recursive, mutual exclusion structure) is held for the duration of callback invocation. Callback functions should be structured accordingly to avoid the potential for deadlock.

Parameters
functionCallback function.
receiverContext pointer for callback function.
Returns
Operation status.
kStatus kAssembly_Enumerate ( kArrayList  assemblies)

Gets a list of the currently-loaded assemblies.

Each assembly returned by this function is a reference-counted instance that should be destroyed when no longer needed.

Parameters
assembliesReceives references to loaded assemblies.
Returns
Operation status.
kStatus kAssembly_FindType ( kAssembly  assembly,
const kChar name,
kType type 
)

Finds a type by name.

Parameters

typeReceives the type.
Returns
Operation status (kERROR_NOT_FOUND on lookup failure).
const kChar * kAssembly_Name ( kAssembly  assembly)

Gets the assembly name.

Parameters
assemblyAssembly.
Returns
Assembly name.
kStatus kAssembly_RemoveLoadHandler ( kCallbackFx  function,
kPointer  receiver 
)

Removes a callback that was registered with the kAssembly_AddLoadHandler function.

Parameters

receiverContext pointer for callback function.
Returns
Operation status.
kStatus kAssembly_RemoveUnloadedHandler ( kCallbackFx  function,
kPointer  receiver 
)

kSize  index 
)

Gets the type at a particular index within an assembly.

Parameters
assemblyAssembly.
indexType index.
Returns
Type.
kSize kAssembly_TypeCount ( kAssembly  assembly)

Gets the number of types in an assembly.

Parameters
assemblyAssembly.
Returns
Operation status.
kVersion kAssembly_Version ( kAssembly  assembly)

Gets the assembly version.

Parameters
assemblyAssembly.
Returns
Version number.
kAlloc kObject_Alloc ( kObject  object)
inherited

Gets the memory allocator associated with this object.

Most objects are constructed with an allocator, which is used to allocate the memory required by the object. Objects retain a reference to this allocator to enable further allocations and to free memory when the object is destroyed.

Parameters
objectObject.
Returns
Memory allocator.
See also
kAlloc, kObject_Alloc_
kStatus kObject_Clone ( kObject object,
kObject  source,
kAlloc  allocator 
)
inherited

Constructs a new object by copying an existing object, including any aggregated child elements.

If the source object is an object collection (e.g. kArrayList<kString>), any aggregated child objects are also cloned. In this case, the kObject_Dispose method can be used to free the cloned collection and its associated elements.

This method will fail if the source object (or an aggregated child element) does not support cloning.

Parameters
objectReceives the constructed object.
sourceSource object.
allocatorMemory allocator (or kNULL for default).
Returns
Operation status.
See also
kObject_Dispose
kStatus kObject_Destroy ( kObject  object)
inherited

Destroys the object.

The kObject_Destroy method destroys the object itself and any resources that are owned by the object. See Object Destruction for more information.

When an object is destroyed (or disposed), its reference count is decremented. The object is only truly destroyed when the reference count reaches zero. See Reference Counting for more information.

Parameters
objectObject (or kNULL).
Returns
Operation status.
See also
Object Destruction, Reference Counting
kStatus kObject_Dispose ( kObject  object)
inherited

Destroys the object and any aggregated child elements.

The kObject_Dispose method destroys the object itself, any resources that are owned by the object, and if the object represents a collection of objects, any child objects in the collection. See Object Destruction for more information.

When an object is destroyed (or disposed), its reference count is decremented. The object is only truly destroyed when the reference count reaches zero. See Reference Counting for more information.

Parameters
objectObject (or kNULL).
Returns
Operation status.

Object Destruction, Reference Counting
kBool kObject_Equals ( kObject  object,
kObject  other 
)
inherited

Determines whether the object is equal to another object.

By default, objects are compared by reference; objects are considered equal if the given handles refer to the same object instance. However, some classes override the Equals method to provide a more meaningful comparison (e.g. kString).

Parameters
objectObject.
otherObject for comparison.
Returns
kTRUE if the objects are equal.
kSize kObject_HashCode ( kObject  object)
inherited

Gets a hash code representing the state of this object.

By default, objects return a hash code based on the object handle value. However, some classes override the HashCode method to provide a more useful hash (e.g. kString).

Parameters
objectObject.
Returns
Hash code.
kBool kObject_Is ( kObject  object,
kType  type 
)
inherited

Determines whether this object is an instance of the specified type.

This function compares the type of this object with the given type. An object is considered to be an instance of a given type if a) the type represents a class and this object inherits from (or instantiates) that class, or b) the type represents an interface and this object implements the interface.

Parameters
objectObject.
typeType.
Returns
kTRUE if the object is of the specified type; otherwise kFALSE.
See also
kObject_Is_, kType_Is
kBool kObject_IsShared ( kObject  object)
inherited

Reports whether the object is currently shared (reference count greater than one).

Objects are initialized with a reference count of one. The kObject_Share method can be used to increment the reference count. The kObject_Destroy and kObject_Dispose methods decrease the reference count, and when the reference count reaches zero, the object is actually destroyed/disposed.

This method can be used to determine if the reference count of an object is currently greater than one.

This method is thread-safe.

Parameters
objectObject.
Returns
kTRUE if the object is shared; kFALSE otherwise.
See also
Reference Counting, kObject_Share
kStatus kObject_SetPool ( kObject  object,
kObjectPool  pool 
)
inherited

Sets the object pool associated with this object.

Object pools can be used to implement custom lifecycle management. If an object has an assigned pool, then the kObjectPool_Reclaim method will be called just prior to destruction, to provide an opportunity for the object to be reclaimed.

Parameters
objectObject.
poolPool object (or kNULL to clear the pool assignment).
Returns
Operation status.
kStatus kObject_Share ( kObject  object)
inherited

Increments the reference count associated with this object.

This method is thread-safe.

Parameters
objectObject.
Returns
Operation status.
See also
reference-counting
kSize kObject_Size ( kObject  object)
inherited

Estimates the memory consumed by this object, including any aggregated child elements.

This method can be optionally overridden by kObject-derived classes to report the amount of memory consumed by an object. The default implementation reports only the size of the class instance (additional allocations performed by the class are excluded).

Parameters
objectObject.
Returns
Object size, in bytes.
kType kObject_Type ( kObject  object)
inherited

Returns the type of the object.

Each object is an instance of a specific class type. The type handle returned by this function can be used to learn about the class.

Parameters
objectObject.
Returns
Type.
