Detailed Description

Base class for a backend layer.

The Kanzi graphics library calls the layers in sequence, so that common features, such as logging or validation, are added to all backends.

Since: Kanzi 4.0.0

Constructor & Destructor Documentation

◆ BackendLayer()

kanzi::gfx::BackendLayer::BackendLayer ( )

default

Constructor.

Member Function Documentation

◆ getNext()

AbstractBackend * kanzi::gfx::BackendLayer::getNext ( ) const

inlineprotected

Accesses the next backend in the chain.

◆ setNext()

void kanzi::gfx::BackendLayer::setNext ( shared_ptr< AbstractBackend > next )

inline

Sets the next backend object in the execution chain.

This operation is part of initialization, and therefore not thread-safe with the next operation or other operations on the interface.

Parameters

next	The next backend in the chain. This can be a real backend or another layer.

◆ initialize()

inlineoverridevirtual

Initializes the backend.

Returns: If initialization was successful, true, otherwise false.

Implements kanzi::gfx::AbstractBackend.

◆ prepareForShutdown()

void kanzi::gfx::BackendLayer::prepareForShutdown ( )
