Class: TLinkedViewMatrixGrafState

Declaration: GrafState.h

Taxonomy Categories:

Member Functions:

Interface Category:

API.

Inherits From:

TLinkedGrafState

Inherited By:

None.

Purpose:

Derived from TLinkedGrafState, TLinkedViewMatrixGrafState links a TGrafMatrix (or TLinkableMatrixState) object to a parent TGrafState object. This class is used internally by TLinkedViewMatrixPort. Most programmers who want to link a 2-D view matrix into a graphics hierarchy use TLinkedViewMatrixPort, instead of using TLinkedViewMatrixGrafState directly.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TLinkedViewMatrixGrafState::TLinkedViewMatrixGrafState

TLinkedViewMatrixGrafState (const TGrafState * parent, const TGrafMatrix & viewMatrix)
TLinkedViewMatrixGrafState (const TGrafState * parent, TLinkableMatrixState * viewMatrixState)

Interface Category:

API.

Purpose:

Constructor that links the specified 2-D view matrix to the specified parent graphics state. A local 2-D matrix state is instantiated and linked to the parent graphics state.
Constructor that links the specified 2-D matrix state to the specified parent graphics state.

Calling Context:

Call this function directly.
Call this function directly.

Parameters:

const TGrafState * parent -The TGrafState to use as the parent.
const TGrafMatrix & viewMatrix -The 2-D view matrix to link to the parent.
const TGrafState * parent -The TGrafState to use as the parent.
TLinkableMatrixState * viewMatrixState -The 2-D matrix state to link to the parent.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.
