Interface TreeNode

All Known Implementing Classes:

AbstractNode

public interface TreeNode

The interface for a node within the Equation parse tree.

Method Summary

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.

Method Detail

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.
