## Member Function Documentation

virtual const char* ExpressionNode::getAttribute | ( | int | k | ) | const`[virtual]`

| Pure virtual method, it should be redefined in subclasses to return the value of the kth attribute (i.e. the attribute with the name getAttributeName(k)). It should return NULL if k is out of range (i.e. negative or greater than getNumAttributes()). Implements NEDElement.

virtual const char* ExpressionNode::getAttributeDefault | ( | int | k | ) | const`[virtual]`

| Pure virtual method, it should be redefined in subclasses to return the default value of the kth attribute, as defined in the DTD. It should return NULL if k is out of range (i.e. negative or greater than getNumAttributes()). Implements NEDElement.

virtual const char* ExpressionNode::getAttributeName | ( | int | k | ) | const`[virtual]`

| Pure virtual method, it should be redefined in subclasses to return the name of the kth attribute as defined in the DTD. It should return NULL if k is out of range (i.e. negative or greater than getNumAttributes()). Implements NEDElement.

virtual ConstNode* ExpressionNode::getFirstConstChild | ( |  | ) | const`[virtual]`

virtual FunctionNode* ExpressionNode::getFirstFunctionChild | ( |  | ) | const`[virtual]`

virtual IdentNode* ExpressionNode::getFirstIdentChild | ( |  | ) | const`[virtual]`

virtual OperatorNode* ExpressionNode::getFirstOperatorChild | ( |  | ) | const`[virtual]`

virtual ParamRefNode* ExpressionNode::getFirstParamRefChild | ( |  | ) | const`[virtual]`

virtual ExpressionNode* ExpressionNode::getNextExpressionNodeSibling | ( |  | ) | const`[virtual]`

virtual int ExpressionNode::getNumAttributes | ( |  | ) | const`[virtual]`

| Pure virtual method, it should be redefined in subclasses to return the number of attributes defined in the DTD. Implements NEDElement.

virtual int ExpressionNode::getTagCode | ( |  | ) | const`[inline, virtual]`

| Overridden in subclasses to return the numeric code (NED_xxx) of the XML element the class represents. Implements NEDElement.

virtual const char* ExpressionNode::getTagName | ( |  | ) | const`[inline, virtual]`

| Overridden in subclasses to return the name of the XML element the class represents. Implements NEDElement.

const char* ExpressionNode::getTarget | ( |  | ) | const`[inline]`

virtual void ExpressionNode::setAttribute | ( | int | k,
|  | const char * | val
| ) | `[virtual]`

| Pure virtual method, it should be redefined in subclasses to set the value of the kth attribute (i.e. the attribute with the name getAttributeName(k)). If k is out of range (i.e. negative or greater than getNumAttributes()), the call should be ignored. Implements NEDElement.

void ExpressionNode::setTarget | ( | const char * | val | ) | `[inline]`
