Constructor Detail

programc

public programc(int lineNumber,
                Classes a1)

Creates "programc" AST node.

Parameters:

lineNumber - the line in the source file from which this node came.

a1 - initial value for classes

Method Detail

copy

public TreeNode copy()

Description copied from class: TreeNode

Creates a copy of this node.

Specified by:

copy in class TreeNode

Returns:

a copy of this node

dump

public void dump(java.io.PrintStream out,
                 int n)

Description copied from class: TreeNode

Pretty-prints this node to this output stream.

Specified by:

dump in class TreeNode

Parameters:

out - the output stream

n - the number of spaces to indent the output

dump_with_types

public void dump_with_types(java.io.PrintStream out,
                            int n)

Specified by:

dump_with_types in class Program

semant

public void semant()

This method is the entry point to the semantic checker. You will need to complete it in programming assignment 4.

Your checker should do the following two things:

1. Check that the program is semantically correct
2. Decorate the abstract syntax tree with type information by setting the type field in each Expression node. (see tree.h)

You are free to first do (1) and make sure you catch all semantic errors. Part (2) can be done in a second stage when you want to test the complete compiler.

Specified by:

semant in class Program

cgen

public void cgen(java.io.PrintStream s)

This method is the entry point to the code generator. All of the work of the code generator takes place within CgenClassTable constructor.

Specified by:

cgen in class Program

Parameters:

s - the output stream
