## Member Function Documentation

unsigned int mask | ( |  | ) | const

Search for all occurrences

Query the clear mask.

Bit flags can be tested with the MClearOperation::ClearMask enumeration.

Returns:
  The clear mask

const float * clearColor | ( |  | ) | const

Search for all occurrences

Query the first clear color value.

Returns:
  Clear color

bool clearGradient | ( |  | ) | const

Search for all occurrences

Query if the clear should clear with a gradient.

Returns:
  Clear gradient flag.

const float * clearColor2 | ( |  | ) | const

Search for all occurrences

Query the second clear color value.

Returns:
  Clear color

int clearStencil | ( |  | ) | const

Search for all occurrences

Query the stencil clear value.

Returns:
  Stencil value

float clearDepth | ( |  | ) | const

Search for all occurrences

Query the clear depth value.

Returns:
  Depth value

void setMask | ( | unsigned int | mask | ) |

Search for all occurrences

Set the clear mask to define which channels to clear.

Parameters:

  [in] | mask | Clear mask to set.

void setClearColor | ( | float | value[4] | ) |

Search for all occurrences

Set the clear color value.

This will be the color used at the top of the gradient if a color gradient is specified.

Parameters:

  [in] | value | Color value to set

void setClearGradient | ( | bool | value | ) |

Search for all occurrences

Set whether to clear with a vertical color gradient.

If a gradient is used then mClearColor is the color at the top of gradient, and mClearColor2 is the color at the bottom of the gradient.

Parameters:

  [in] | value | Whether to use a gradient

void setClearColor2 | ( | float | value[4] | ) |

Search for all occurrences

Set the clear second color value.

Only used when a color gradient is to be used.

Parameters:

  [in] | value | Color value to set

void setClearStencil | ( | int | value | ) |

Search for all occurrences

Set the clear stencil value.

Parameters:

  [in] | value | Stencil value

void setClearDepth | ( | float | value | ) |

Search for all occurrences

Set the clear depth value.

Parameters:

  [in] | value | Depth value
