Compositor() [2/3]

Fove::Compositor::Compositor

(

Fove_Compositor &

compositor

)

Creates a compositor from an existing C API object.

This is not normally invoked directly, rather Headset::createCompositor(), which wraps this, is typically used.

Compositor() [3/3]

Fove::Compositor::Compositor

(

Compositor &&

other

Move constructs a compositor.

Parameters

other

May be empty or non-empty. By return, it will be empty.

~Compositor()

Fove::Compositor::~Compositor

(

)

Since an error cannot be returned, any error from fove_Compositor_destroy will be logged.

Here is the call graph for this function:

Member Function Documentation

destroy()

Result Fove::Compositor::destroy

(

)

Destroys the compositor object, releasing resources.

After this call, this object will be in an empty state and future calls will fail. This is handled by the destructor, usually the user doesn't need to call this.

Here is the call graph for this function:

operator=()

Compositor& Fove::Compositor::operator=

(

Compositor &&

other

)

Destroys the existing compositor if any, then moves the one referenced by other, if any, into this object.

Parameters

other

May be empty or non-empty. By return, it will be empty.

Here is the call graph for this function:

queryAdapterId()

Result<AdapterId> Fove::Compositor::queryAdapterId

(

AdapterId *

ignore = nullptr

)

Wraps fove_Compositor_queryAdapterId()

Parameters

ignore

This is not used and will be removed in a future version
