public bool CanClearBeforeRender()

Public Function CanClearBeforeRender As Boolean

public:
bool CanClearBeforeRender()

member CanClearBeforeRender : unit -> bool 

Return Value

This allows a subclass to forbid the color buffer from being cleared before any rendering. Typically, this takes place after rendering the first view. Then, if canClearBeforeRender() returns false, the color buffer can keep previous modifications, such as for the stencil buffer, etc.
