Constructor Detail

leq

public leq(int lineNumber,
           Expression a1,
           Expression a2)

Creates "leq" AST node.

Parameters:

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

a1 - initial value for e2

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 Expression

code

public void code(java.io.PrintStream s)

Generates code for this expression. This method is to be completed in programming assignment 5. (You may add or remove parameters as you wish.)

Specified by:

code in class Expression

Parameters:

s - the output stream

get_type

public AbstractSymbol get_type()

                      int n)

set

public TreeNode set(TreeNode other)

Sets the values of this node object to the values of a given node.

Parameters:

other - the other node

Returns:

this node

getLineNumber

public int getLineNumber()

Retreives the line number from which this node came.

Returns:

the line number

copy_Boolean

protected java.lang.Boolean copy_Boolean(java.lang.Boolean b)

Copies a boolean value. This method is used internally by the generated AST classes

copy_AbstractSymbol

protected AbstractSymbol copy_AbstractSymbol(AbstractSymbol sym)

Copies an AbstractSymbol value. This method is used internally by the generated AST classes

dump_Boolean

protected void dump_Boolean(java.io.PrintStream out,
                            int n,
                            java.lang.Boolean b)

Dumps a printable representation of a boolean value. This method is used internally by the generated AST classes

dump_AbstractSymbol

protected void dump_AbstractSymbol(java.io.PrintStream out,
                                   int n,
                                   AbstractSymbol sym)

Dumps a printable representation of an AbstactSymbol value. This method is used internally by the generated AST classes

dump_line

protected void dump_line(java.io.PrintStream out,
                         int n)

Dumps a printable representation of current line number This method is used internally by the generated AST classes
