Detailed Description

A reference counted module resource.

Constructor & Destructor Documentation

pp::Resource::Resource

(

)

The default constructor.

pp::Resource::Resource

(

const Resource &

other

)

A constructor for copying a resource.

Parameters

[in]

other

A Resource.

virtual pp::Resource::~Resource ( )

virtual

Destructor.

pp::Resource::Resource ( PP_Resource  resource )

explicitprotected

A constructor used when a PP_Resource is provided as a return value whose reference count we need to increment.

Parameters

[in]

resource

A PP_Resource corresponding to a resource.

pp::Resource::Resource ( PassRef  , PP_Resource  resource  )

protected

Constructor used when a PP_Resource already has a ref count assigned. Add additional refcount is not taken.

Member Function Documentation

PP_Resource pp::Resource::detach

(

)

This function releases ownership of this resource and returns it to the caller.

Note that the reference count on the resource is unchanged and the caller needs to release the resource.

Returns

The detached PP_Resource.

bool pp::Resource::is_null ( ) const

inline

This functions determines if this resource is invalid or uninitialized.

Returns

true if this resource is invalid or uninitialized.

Definition at line 43 of file resource.h.

Resource& pp::Resource::operator=

(

const Resource &

other

)

This function assigns one Resource to another Resource.

Parameters

[in]

other

A Resource.

Returns

A Resource containing the assigned Resource.

void pp::Resource::PassRefFromConstructor ( PP_Resource  resource )

protected

PassRefFromConstructor is called by derived class' constructors to initialize this Resource with a PP_Resource that has already had its reference count incremented by Core::AddRefResource. It also assumes this object has no current resource.

The intended usage of this function that the derived class constructor will call the default Resource constructor, then make a call to create a resource. It then wants to assign the new resource (which, since it was returned by the browser, already had its reference count increased).

Parameters

[in]

resource

A PP_Resource corresponding to a resource.

PP_Resource pp::Resource::pp_resource ( ) const

inline
