Detailed Description

A reference counted module resource.

Constructor & Destructor Documentation

pp::Resource::Resource ( )

The default constructor.

pp::Resource::Resource ( const Resource & other )

[in] other A Resource.

virtual pp::Resource::~Resource ( ) [virtual]

Destructor.

pp::Resource::Resource ( PP_Resource resource ) [explicit, protected]

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.

Member Function Documentation

void pp::Resource::Clear ( ) [protected]

Sets this resource to null. This releases ownership of the resource.

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.

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]
