CComSingleThreadModel Class

This class provides methods for incrementing and decrementing the value of a variable.

class CComSingleThreadModel

Members

Public Typedefs

Name	Description
CComSingleThreadModel::AutoCriticalSection	References class CComFakeCriticalSection.
CComSingleThreadModel::CriticalSection	References class CComFakeCriticalSection.
CComSingleThreadModel::ThreadModelNoCS	References CComSingleThreadModel.

Public Methods

Name	Description
CComSingleThreadModel::Decrement	Decrements the value of the specified variable. This implementation is not thread-safe.
CComSingleThreadModel::Increment	Increments the value of the specified variable. This implementation is not thread-safe.

Remarks

CComSingleThreadModel provides methods for incrementing and decrementing the value of a variable. Unlike CComMultiThreadModel and CComMultiThreadModelNoCS, these methods are not thread-safe.

Typically, you use CComSingleThreadModel through one of two typedef names, either CComObjectThreadModel or CComGlobalsThreadModel. The class referenced by each typedef depends on the threading model used, as shown in the following table:

typedef	Single threading model	Apartment threading model	Free threading model
CComObjectThreadModel	S	S	M
CComGlobalsThreadModel	S	M	M

S=CComSingleThreadModel; M=CComMultiThreadModel

CComSingleThreadModel itself defines three typedef names. ThreadModelNoCS references CComSingleThreadModel. AutoCriticalSection and CriticalSection reference class CComFakeCriticalSection, which provides empty methods associated with obtaining and releasing ownership of a critical section.
