class ManipStrategy : public CAVERNmisc_subject_c

Abstract manipulation strategy class

Inheritance:

Public Methods

ManipStrategy()

constructor.

virtual ~ManipStrategy()

destructor.

inline void setDCS( pfNetDCS *aDCS )

Sets the DCS being manipulated by the strategy

inline void setParent( pfGroup *aParent )

Sets the parent node

virtual void eval()

Pure virtual evaluation of the strategy

Protected Fields

pfGroup* parent

parent of the node to be affected.

pfNetDCS* dcs

references to the netDCS

ManipStrategy()

constructor.

virtual ~ManipStrategy()

destructor.

inline void setDCS( pfNetDCS *aDCS )

Sets the DCS being manipulated by the strategy. When the manipulator is attached to the node, it will call this function to ensure the strategy has its own reference to the node being modified. The programmer need not call this function manually.

Parameters:

aDCS - DCS which will be affected by this strategy

inline void setParent( pfGroup *aParent )

Sets the parent node. When the manipulator is attached to the node, it will call this function to ensure the strategy has its own reference to the parent of the modified node. The programmer need not call this function manually. It can be used to help create graphical indicators for manipulation.

Parameters:

aParent - parent node of the manipuled DCS

virtual void eval()

Pure virtual evaluation of the strategy. Any implemented subclass must specify the algorithm used to modify the node to which the MCS has been attached.

pfGroup* parent

parent of the node to be affected.

pfNetDCS* dcs

references to the netDCS
