makeExpression

public static Expression makeExpression(Environment env,
                                        String str)
                                 throws MOPException

Converts a string into an expression. For example:

     "i + 3"
 

or :

     "f()"
 

Returns:

the expression node which the specified string represents.

Throws:

MOPException - if any critical error occurs.

                               throws MOPException

Converts a string into a statement. For example:

     "i++;"
 

or :

     "for(;;){ f(); }"
 

But local variable declarations are not allowed.

Returns:

the statement node which the specified string represents.

Throws:

MOPException - if any critical error occurs.

makeStatementList

public static StatementList makeStatementList(Environment env,
                                              String str)
                                       throws MOPException

     "i++; j = 3;"
 

Local variable declarations like following can also be parsed.

     "int  n, m;"
 

Returns:

the statements node which the specified string represents.

Throws:

MOPException - if any critical error occurs.
