## Detailed Description

GENERATED CLASS. Represents the <expression> XML element in memory. DTD declaration:

     <!ELEMENT expression ((operator|function|param-ref|ident|const))>
     <!ATTLIST expression
          target              NMTOKEN   IMPLIED >

## Member Function Documentation

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()). Reimplemented from NEDElement.

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()). Reimplemented from NEDElement.

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()). Reimplemented from NEDElement.

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

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

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

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

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

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

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. Reimplemented from NEDElement.
