Detailed Description

A Notifier both sends notifications to and receives notifications from other Notifiers.

This is accomplished through the Notify() function, which calls OnNotify() on all held Notifiers.

Constructor & Destructor Documentation

ion::base::Notifier::Notifier ( )
inlineprotected

The constructor is protected because this is a base class and should not be created on its own.

Definition at line 54 of file notifier.h.

ion::base::Notifier::~Notifier ( )
overrideprotected

The destructor is protected because this is derived from Referent.

Member Function Documentation

void ion::base::Notifier::AddReceiver ( Notifier receiver)

Adds a Notifier to be notified.

Does nothing if the receiver is NULL or is already in the receiver vector.

Definition at line 25 of file notifier.cc.

const AllocatorPtr& ion::base::Allocatable::GetAllocator ( ) const
inlineinherited

Returns the Allocator that was used for the instance.

This will be NULL if the instance was declared on the stack or created with normal placement new.

Definition at line 68 of file allocatable.h.

References allocator_.

const AllocatorPtr& ion::base::Allocatable::GetNonNullAllocator ( ) const
inlineinherited

Return our allocator, or the default allocator if the instance was declared on the stack.

Definition at line 72 of file allocatable.h.

References allocator_, and ion::base::AllocationManager::GetNonNullAllocator().

size_t ion::base::Notifier::GetReceiverCount ( ) const

Returns the number of Notifiers that will be notified.

Definition at line 71 of file notifier.cc.

const Notifier::NotifierPtrVector & ion::base::Notifier::GetReceivers ( ) const
protected

Returns the set of Notifiers that will be notified.

Definition at line 77 of file notifier.cc.

int ion::base::Shareable::GetRefCount ( ) const
inlineinherited

GetRefCount() is part of the interface necessary for SharedPtr.

Definition at line 34 of file shareable.h.

Referenced by RemoveReceiver().

void ion::base::Notifier::Notify ( ) const
protected

Notifies all contained Notifiers by calling their OnNotify().

Any receivers that have been destroyed will be removed from the vector of receivers.

Definition at line 81 of file notifier.cc.

References ion::base::SharedPtr< T >::Get().

void ion::base::Notifier::OnNotify ( const Notifier notifier)
protectedvirtual

Subclasses can override this to provide custom behavior on notifications.

void ion::base::Allocatable::operator delete ( void *  ptr)
inlineinherited

Define the delete operator to use specialized functions dealing with an Allocator.

Definition at line 109 of file allocatable.h.

void ion::base::Allocatable::operator delete ( void *  ptr,
AllocationLifetime  lifetime 
)
inlineinherited

Windows requires these (or it issues C4291 warnings).

Definition at line 112 of file allocatable.h.

void ion::base::Allocatable::operator delete ( void *  ptr,
const AllocatorPtr allocator 
)
inlineinherited

Definition at line 113 of file allocatable.h.

void ion::base::Allocatable::operator delete ( void *  ptr,
void *  ptr2 
)
inlineinherited

The placement delete operator does nothing, as usual.

Definition at line 118 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t  size)
inlineinherited

The standard no-parameter new operator uses the default Allocator.

Definition at line 84 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t  size,
AllocationLifetime  lifetime 
)
inlineinherited

This overloaded version of the new operator uses the AllocationManager's default Allocator for the specified lifetime.

Definition at line 88 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t  size,
const AllocatorPtr allocator 
)
inlineinherited

This overloaded version of the new operator takes the Allocator to use directly as a parameter.

If the Allocator pointer is NULL, this uses the default Allocator.

Definition at line 95 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t  size,
const AllocatorPtr allocator,
void *  ptr 
)
inlineinherited

Special operator new for using placement new with Allocatables.

Definition at line 100 of file allocatable.h.

void* ion::base::Allocatable::operator new ( size_t  size,
void *  ptr 
)
inlineinherited

The placement new operator is defined conventionally.

Definition at line 105 of file allocatable.h.

void ion::base::Notifier::RemoveReceiver ( Notifier receiver)

Removes a Notifier to be notified.

Does nothing if the receiver is NULL or not in the set of receivers.

Definition at line 38 of file notifier.cc.
