Constructors

o Espresso 
 public Espresso()
The only constructor.

Methods

o defineInitEnv

Define entries in the symbol table for all the primops. This entries will be used by the type checker. The entries in the symbol table must be sorted from the widest type (e.g, double) to the narrowest (e.g, int).

o execute 
 public void execute(String args[])
Espresso's main loop.

o internalError 
 public static void internalError()
Aborts the execution of the compiler as a result of an unrecoverable error.

o notYetImplemented 
 public static void notYetImplemented()
Aborts the execution of the compiler if something found in the source file can't be compiled.

o printErrors 
 private void printErrors()
o errors 
 public static Vector errors()
o symbolTable 
 public static SymbolTable symbolTable()
o fileName 
 public static String fileName()
o importMgr 
 public static JavaImportManager importMgr()
o currentPackage 
 public static Symbol currentPackage()
o currentClass 
 public static void currentClass(Symbol name)
o currentClass 
 public static Symbol currentClass()
o main 
 public static void main(String args[])
Entry point.
