Constructor Detail

EGLGraphicsDevice

public EGLGraphicsDevice(String connection,
                 int unitID)

Note that this is not an open connection, ie no native display handle exist. This constructor exist to setup a default device connection/unit.

EGLGraphicsDevice

public EGLGraphicsDevice(long nativeDisplayID,
                 long eglDisplay,
                 String connection,
                 int unitID,
                 EGLGraphicsDevice.EGLDisplayLifecycleCallback eglLifecycleCallback)

Method Detail

getNativeDisplayID

public long getNativeDisplayID()

clone

public Object clone()

Overrides:

clone in class DefaultGraphicsDevice

open

public boolean open()

Description copied from interface: AbstractGraphicsDevice

Optionally [re]opening the device if handle is null.

The default implementation is a NOP.

Example implementations like X11GraphicsDevice or EGLGraphicsDevice issue the native open operation in case handle is null.

Specified by:

open in interface AbstractGraphicsDevice

Overrides:

open in class DefaultGraphicsDevice

Returns:

true if the handle was null and opening was successful, otherwise false.

close

public boolean close()

Description copied from interface: AbstractGraphicsDevice

Optionally closing the device if handle is not null.

The default implementation is a NOP, just setting the handle to null.

Example implementations like X11GraphicsDevice or EGLGraphicsDevice issue the native close operation or skip it depending on the handles's ownership.

Specified by:

close in interface AbstractGraphicsDevice

Overrides:

close in class DefaultGraphicsDevice

Returns:

true if the handle was not null and closing was successful, otherwise false.

toString

public String toString()

Overrides:

toString in class DefaultGraphicsDevice
