Constructor Detail

Program

public Program()

Make an empty program.

Program

public Program(java.util.List<java.lang.String> files)

Make a program from a group of source files.

Parameters:

files - A list of strings that are source file names.

Program

public Program(java.lang.String[] files)

Make a program from a group of source files.

Parameters:

files - An array of strings that are source file names.

Method Detail

addTranslationUnit

public void addTranslationUnit(TranslationUnit tunit)

Adds a translation unit to the program.

Parameters:

tunit - The translation unit to add. Its parent will be set to this program.

defaultPrint

public static void defaultPrint(Program p,
                java.io.PrintWriter o)

Prints the entire program to a stream.

Parameters:

p - The program to print.

o - The writer for the prorgram to be printed on.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getChildren

public java.util.List<Traversable> getChildren()

Description copied from interface: Traversable

Provides access to the children of this object as a list. This object is free to internally implement its list as a LinkedList or an ArrayList. It is generally not good practice to call this method yourself; the ordering of children is not guaranteed so instead you should use the methods of the particular class whose children you wish to access.

Specified by:

getChildren in interface Traversable

Returns:

the children as a list.

getParent

public Traversable getParent()

Description copied from interface: Traversable

Provides access to the parent of this object. Every IR object has at most one parent. (The parent relationship is the same as the parent relationship in the parse tree, and is not to be confused with the base class of a derived class declaration.)

Specified by:

getParent in interface Traversable

Returns:

the parent of this object.

print

public void print()
           throws java.io.IOException

Write all translation units to their respective files.

Throws:

java.io.FileNotFoundException - if a file could not be opened.

java.io.IOException

print

public void print(java.io.PrintWriter o)

Description copied from interface: Printable

Print the code for the IR represented by the object. Always calls object_print_method(this, o). If the object's print method is null, nothing is printed; this provides an easy mechanism to temporarily hide something.

Specified by:

print in interface Printable

Parameters:

o - The writer on which to print the data.

removeChild

public void removeChild(Traversable child)

Description copied from interface: Traversable

Removes the specified child.

Specified by:

removeChild in interface Traversable

Parameters:

child - a reference to a child object that must match with ==.

setChild

public void setChild(int index,
            Traversable t)

Description copied from interface: Traversable

Sets the indexth child of this object to t. By calling this method, the old child located at the position i will have a null parent. It is generally not good practice to call this method yourself; the ordering of children is not guaranteed so instead you should use the methods of the particular class whose children you wish to access. There are checks to prevent such actions as making a statement a child of an expression, but you still may be able to do some damage with this method if you are not careful.

Specified by:

setChild in interface Traversable

setClassPrintMethod

public static void setClassPrintMethod(java.lang.reflect.Method m)

Overrides the class print method, so that all subsequently created objects will use the supplied method.

Parameters:

m - The new print method.

setParent

public void setParent(Traversable t)

Unsupported - the parent of a program is null and may not be changed.

Specified by:

setParent in interface Traversable

setPrintMethod

public void setPrintMethod(java.lang.reflect.Method m)

Overrides the print method for this object only.

Parameters:

m - The new print method.

createNewDDGraph

public void createNewDDGraph()

Adds a Data Dependence Graph Object to this program, created by DDTDriver

getDDGraph

public DDGraph getDDGraph()

Return program data dependence graph
