Detailed Description

template<class Resource>
class RWTReadGuardBase< Resource >

RWTReadGuardBase is a base class for guard classes that support read access to a given section of code.

Guard objects work in conjunction with block statements to establish an appropriate state upon creation, maintain that state for the duration of the block, and restore the original state upon destruction. For example, a guard may acquire a mutex for reading upon creation and release it when destructed. The class used as the template parameter Resource must be one that provides acquireRead() and release() methods, such as the synchronization classes provided in this module.

Constructor & Destructor Documentation

template<class Resource >

RWTReadGuardBase< Resource >::~RWTReadGuardBase

(

)

Destructor.

template<class Resource >

RWTReadGuardBase< Resource >::RWTReadGuardBase ( Resource &  resource )

inlineprotected

Deprecated:

As of SourcePro 13, use RWTReadGuardBase(Resource&, bool) instead.

Constructs an instance with the given resource.

template<class Resource >

RWTReadGuardBase< Resource >::RWTReadGuardBase ( Resource &  resource, bool  acquired  )

inlineprotected

Constructs an instance with the given resource. If acquired is true, the resource is assumed to be owned by the caller.

template<class Resource >

RWTReadGuardBase< Resource >::RWTReadGuardBase ( const RWTReadGuardBase< Resource > &  second )

private

Copy construction prohibited.

Member Function Documentation

template<class Resource >

void RWTReadGuardBase< Resource >::acquire ( void  )

inline

Acquires read access on the resource held by the guard unless access has already been acquired. Use this function rather than manipulating the resource directly so the guard will automatically release or acquire access (as appropriate).

template<class Resource >

bool RWTReadGuardBase< Resource >::isAcquired ( ) const

inline

Returns true if the resource is currently acquired.

template<class Resource >

RWTReadGuardBase<Resource>& RWTReadGuardBase< Resource >::operator= ( const RWTReadGuardBase< Resource > &  second )

private

Assignment prohibited.

template<class Resource >

void RWTReadGuardBase< Resource >::release ( void  )

inline

Releases the resource held by the guard if it has been acquired. Use this function rather than manipulating the resource directly so the guard will automatically release or acquire access (as appropriate).

template<class Resource >

Resource & RWTReadGuardBase< Resource >::resource ( ) const

inlineprotected

Returns a reference to the resource currently held by the guard.
