All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`genCode(Stack<CodeAndSourceLocation> codeStack)`	Generated code for this node and pushes it onto the execution stack.
`TreeNode`	`getLeftChild()`	Returns the left child if it exists or null if it doesn't.
`TreeNode`	`getRightChild()`	Returns the right child if it exists or null if it doesn't.
`int`	`getSourceLocation()`	Returns the start of the location in the equation where the code was found that was turned into a node in the parse tree.
`Class`	`getType()`	Returns the type of this node.

  - getSourceLocation
```
int getSourceLocation()
```
    Returns the start of the location in the equation where the code was found that was turned into a node in the parse tree.
    
    Returns:
    
    the location in the source code that resulted in this node
  - getType
```
Class getType()
```
    Returns the type of this node.
    
    Returns:
    
    the type of the result of the code generated from this node will result in
  - getLeftChild
```
TreeNode getLeftChild()
```
    Returns the left child if it exists or null if it doesn't.
    
    Returns:
    
    the left child, if any, of this node in the parse tree
  - getRightChild
```
TreeNode getRightChild()
```
    Returns the right child if it exists or null if it doesn't.
    
    Returns:
    
    the right child, if any, of this node in the parse tree
  - genCode
```
void genCode(Stack<CodeAndSourceLocation> codeStack)
```
    Generated code for this node and pushes it onto the execution stack.
    
    Parameters:
    
    codeStack - the execution stack to push the generated code for this node.
