Interface Category:

API.

Inherits From:

TLinkedGrafPort

Inherited By:

None.

Purpose:

TLinkedModelMatrix3DPort is a concrete class, derived from TLinkedGrafPort, that concatenates a 3-D model matrix with a parent port. The model matrix is specified by an argument to the TLinkedModelMatrix3DPort constructor. The child's model matrix is the concatenation of the parent port's model matrix with the model matrix specified by the constructor argument.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

The parent port must exist as long as the child port exists.

Member Function: TLinkedModelMatrix3DPort::TLinkedModelMatrix3DPort

TLinkedModelMatrix3DPort (TGrafPort * referencedParentPort, const TGrafMatrix3D & modelMatrix)
TLinkedModelMatrix3DPort (TGrafPort * referencedParentPort, TLinkableMatrix3DState * referencedMatrixState)

Interface Category:

API.

Purpose:

Constructs a new TLinkedModelMatrix3DPort with the specified TGrafPort as its parent, concatenating the model matrix specified by the TGrafMatrix3D argument with the parent port's state.
Constructs a new TLinkedModelMatrix3DPort with the specified TGrafPort as its parent, concatenating the model matrix specified by the TLinkableMatrix3DState argument with the parent port's state.

Parameters:

TGrafPort * referencedParentPort -The graph port to use as the parent.
const TGrafMatrix3D & modelMatrix -The model matrix state to concatenate with the parent port's state.
TGrafPort * referencedParentPort -The graph port to use as the parent.
TLinkableMatrix3DState * referencedMatrixState -The matrix state object to concatenate with the parent port's state.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Other Considerations:

None.

Member Function: TLinkedModelMatrix3DPort::~TLinkedModelMatrix3DPort

virtual ~ TLinkedModelMatrix3DPort ()

Interface Category:

API.

Purpose:

Destructor.

Calling Context:

Called to destroy an object.

Parameters:

Takes no parameters.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.

Member Function: TLinkedModelMatrix3DPort::GetState

virtual const TGrafState * GetState () const

Interface Category:

API.

Purpose:

Returns a pointer to a TGrafState object that represents the concatenated graphic state of this object.

Calling Context:

Do not call this function directly. This function is designed to be called by internal classes of the Graphics system (most notably, TGrafStateAccessor).

Parameters:

Takes no parameters.

Return Value:

Returns a constant pointer to the concatenated graphic state.

Exceptions:

Throws no exceptions, passes all exceptions through.

Concurrency:

Not multithread safe.

Other Considerations:

None.
