Method Detail

lockResources

public boolean lockResources(PresentableState pState)

Description copied from interface: Presentable

Locks any underlying resources needed for a createGraphics/prepare/present sequence and returns a boolean indicating if the presentable needs to be recreated. If the method returns true and the Presentable implements GraphicsResource then its dispose() method will be called prior to recreating a new Presentable object and so no resource should need to be locked in that case. The resources will be unlocked in either #prepare() or Presentable.present().

Specified by:

lockResources in interface Presentable

Parameters:

pState - The presentation state for the upcoming pulse

Returns:

true if the caller should recreate the Presentable

prepare

public boolean prepare(Rectangle dirtyregion)

Description copied from interface: Presentable

display the indicated region to the user.

Specified by:

prepare in interface Presentable

Parameters:

dirtyregion - display region or null for full area

Returns:

true if the provided region was successfully displayed, false otherwise

present

public boolean present()

Description copied from interface: Presentable

present the prepared region to the user.

Specified by:

present in interface Presentable

getPixelScaleFactor

public float getPixelScaleFactor()

Specified by:

getPixelScaleFactor in interface Presentable

getContentWidth

public int getContentWidth()

Description copied from interface: Texture

Returns the content width of this texture, in pixels. Note that the content size of a texture may be smaller than the requested size due to hardware restrictions (e.g. lack of non-power-of-two texture support). The content width will be less than or equal to the content width.

For example, if the hardware does not support non-power-of-two textures, and you call ResourceFactory.createTexture(400, 200), the returned Texture will have physical dimensions of 512x256, but the content dimensions will be 400x200.

Specified by:

getContentWidth in interface Surface

Specified by:

getContentWidth in interface Texture

Overrides:

getContentWidth in class SWTexture

Returns:

the content width of this texture, in pixels

getContentHeight

public int getContentHeight()

Description copied from interface: Texture

Returns the content height of this texture, in pixels. Note that the content size of a texture may be smaller than the requested size due to hardware restrictions (e.g. lack of non-power-of-two texture support). The content height will be less than or equal to the content height.

For example, if the hardware does not support non-power-of-two textures, and you call ResourceFactory.createTexture(400, 200), the returned Texture will have physical dimensions of 512x256, but the content dimensions will be 400x200.

Specified by:

getContentHeight in interface Surface

Specified by:

getContentHeight in interface Texture

Overrides:

getContentHeight in class SWTexture

Returns:

the content height of this texture, in pixels

isMSAA

public boolean isMSAA()

Specified by:

isMSAA in interface RenderTarget

Overrides:

isMSAA in class SWRTTexture
