Member Function Documentation

Resource::State Resources::Resource::Load (  )  [virtual, inherited]

load the resource

This loads the resource through the attached resource loader. Depending on the resource loader, the resource may happen synchronously or asynchronously. If the resource is loaded asynchronously, the IsPending() method will return true as long as the load is in progress, and IsLoaded() will become true when the loading process has finished. If the load has failed, IsPending() will switch to false and IsLoaded() will not be true.

bool Resources::Resource::Save (  )  [virtual, inherited]

save the resource

This will save the resource. A resource saver must be attached to the resource and the resource must be loaded for the method to succeed. Saving will always be performed synchronously.

int Core::RefCounted::GetRefCount (  )  const [inline, inherited]

get the current refcount

Return the current refcount of the object.

void Core::RefCounted::AddRef (  )  [inline, inherited]

increment refcount by one

Increment the refcount of the object.

void Core::RefCounted::Release (  )  [inline, inherited]

decrement refcount and destroy object if refcount is zero

Decrement the refcount and destroy object if refcount is zero.

const Util::String & Core::RefCounted::GetClassName (  )  const [inline, inherited]

get the class name

Get the class name of the object.

Util::FourCC Core::RefCounted::GetClassFourCC (  )  const [inline, inherited]

get the class FourCC code

Get the class FourCC of the object.

void Core::RefCounted::DumpRefCountingLeaks (  )  [static, inherited]

dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)

This method should be called as the very last before an application exits.
