virtual int getFields(MwFieldList &list): Returns a list of fields in this node/engine
virtual MwNode* getMwNode(): Indirection function for protos
const MwName& getName(): To confuse the issue further, I've set pfNode's name using these functions, if the MwNode is also a pfNode
virtual MwNode* getNode()
virtual pfNode* getPfNode(): non null if node is a pfNode
virtual pfMatrix* getTraversal(): Returns the current transformation matrix of the parent node
virtual MwType* getType()
const char* getTypeName()
virtual MbBool handleFieldChange(MwField *field): Returns true if it handled the field change
static void init(): Called by MwDB::init(). Make sure it is called only once

MbBool isConstructed()
MbBool isDirty()
MbBool isEvaluating()
virtual int isExactType(MwType *_type)
MbBool isNotifyingParents()
virtual int isOfType(MwType *_type)
void makeClean()
virtual void makeNode(MwSceneState *sceneState): Initializes the node
MwNode()
virtual void notify(MwField *): Called for each route
virtual MbBool readInstance(MwInput *in): Reads instance from in, and then calls makeNode()
void ref(): Adds reference
void removeParent(MwField *pField)
void setIsEvaluating(MbBool flag): Indicates whether the node is in the process of evaluating itself Needed to prevent recursive calls to container=>update() in e
void setName(const MwName &name)
void setNotifyParents(MbBool flag): Indicates whether notification will propagate to parent Nodes as the result of setting the node value
void unref(): Removes reference, deletes if now 0
void unrefNoDelete(): Removes reference, never deletes
virtual void update(): notifies its eventOuts and auditors that this object has changed
virtual ~MwNode()

Protected Classes

struct

unsigned int dirtyFields : 29: if non-zero, holds the OR-ed masks of the fields that are in the fieldData list that have been marked dirty
unsigned int notifyParents : 1
unsigned int isEvaluating: 1
unsigned int constructed: 1

Protected Fields
static MwType* classType: classType defines making MwNodes similar to pfNodes

Protected Methods
static int getBitMask(int i): Each field has a bitmask corresponding to its position in fieldData
static const MwFieldData** getFieldDataPtr(): This is used by the field-inheritence mechanism, hidden in the MwSubNode macros

MwNode()

virtual ~MwNode()

MwFieldList parentFields

List of parent SFNodes or MFNodes which contains this node.

void addParent(MwField *pField)

void removeParent(MwField *pField)

const MwName& getName()

To confuse the issue further, I've set pfNode's name using these functions, if the MwNode is also a pfNode. While getting name from getName, either pfNode's or MwNode's getName() will give the same name. However, woe betides s/he who set's name using only pfNode's getName.

void setName(const MwName &name)

void ref()

Adds reference

void unref()

Removes reference, deletes if now 0

void unrefNoDelete()

Removes reference, never deletes

virtual int getFields(MwFieldList &list)

Returns a list of fields in this node/engine. This is virtual so private fields can be hidden. Use getFieldName to get the names of the fields, and use MwField::getType() to figure out their types. The number of fields added to the list is returned.

virtual MwField* getField(const MwName &n)
