Constructor Details
- EGLGraphicsDevice
  
  public EGLGraphicsDevice()
  
  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(AbstractGraphicsDevice aDevice, long eglDisplay, EGLGraphicsDevice.EGLDisplayLifecycleCallback eglLifecycleCallback)
- EGLGraphicsDevice
  
  public EGLGraphicsDevice(long nativeDisplayID, long eglDisplay, String connection, int unitID, EGLGraphicsDevice.EGLDisplayLifecycleCallback eglLifecycleCallback)
Method Details
- getEGLVersion
  
  public com.jogamp.common.util.VersionNumber getEGLVersion()
  
  EGL server version as returned by eglInitialize(..). Only valid after open().
- getNativeDisplayID
  
  public long getNativeDisplayID()
- clone
  
  public Object clone()
  
  Specified by:
  
  clone in interface AbstractGraphicsDevice
  
  Overrides:
  
  clone in class DefaultGraphicsDevice
- open
  
  public boolean open()
  
  Opens the EGL device if handle is null and it's EGLGraphicsDevice.EGLDisplayLifecycleCallback is valid.
  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()
  
  Closes the EGL device if handle is not null and it's EGLGraphicsDevice.EGLDisplayLifecycleCallback is valid.
  Optionally closing the device if handle is not null.
  The default implementation dispose it's ToolkitLock and sets 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.
- isHandleOwner
  
  public boolean isHandleOwner()
  
  Specified by:
  
  isHandleOwner in interface AbstractGraphicsDevice
  
  Overrides:
  
  isHandleOwner in class DefaultGraphicsDevice
  
  Returns:
  
  true if instance owns the handle to issue AbstractGraphicsDevice.close(), otherwise false.
- clearHandleOwner
  
  public void clearHandleOwner()
  
  Specified by:
  
  clearHandleOwner in interface AbstractGraphicsDevice
  
  Overrides:
  
  clearHandleOwner in class DefaultGraphicsDevice
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class DefaultGraphicsDevice
