Method Detail

getLabels

public java.lang.String[] getLabels()

Returns a list of labels corresponding to each statistic.

Returns:

a list of labels corresponding to each statistic.

getData(int[])

getData

public void getData(int[] data)

Retrieves the statistics data into the given array. The array should be as large as the array given in getLabels().

Parameters:

data - The data array to write to

onMeshDrawn

public void onMeshDrawn(Mesh mesh,
                        int lod,
                        int count)

Called by the Renderer when a mesh has been drawn.

Parameters:

mesh - the Mesh that was drawn (not null)

lod - which level of detail

count - multiplier for triangles and vertices

onMeshDrawn

public void onMeshDrawn(Mesh mesh,
                        int lod)

Called by the Renderer when a mesh has been drawn.

Parameters:

mesh - the Mesh that was drawn (not null)

lod - which level of detail

onShaderUse

public void onShaderUse(Shader shader,
                        boolean wasSwitched)

Called by the Renderer when a shader has been utilized.

Parameters:

shader - The shader that was used

wasSwitched - If true, the shader has required a state switch

onUniformSet

public void onUniformSet()

Called by the Renderer when a uniform was set.

onTextureUse

public void onTextureUse(Image image,
                         boolean wasSwitched)

Called by the Renderer when a texture has been set.

Parameters:

image - The image that was set

wasSwitched - If true, the texture has required a state switch

onFrameBufferUse

public void onFrameBufferUse(FrameBuffer fb,
                             boolean wasSwitched)

Called by the Renderer when a framebuffer has been set.

Parameters:

fb - The framebuffer that was set

wasSwitched - If true, the framebuffer required a state switch
