uniqueNames

static void uniqueNames(Vector v,
                        String varName,
                        String typeName)
                 throws BadSemanticsException

Compares elements in a Vector of BaseTypes and throw a BadSemanticsException if there are any duplicate elements.

Parameters:

v - The Vector to check

varName - the name of the variable which called us

typeName - the type name of the variable which called us

Throws:

BadSemanticsException - if there are duplicate elements

IndexOutOfBoundsException - if size doesn't match the number of elements in the Enumeration

sortedNames

static String[] sortedNames(Vector v)
                     throws BadSemanticsException

Takes a Vector of BaseTypes, retrieves their names into an array of Strings, and performs a Quick Sort on that array.

Parameters:

v - The Vector to check

Returns:

a sorted array of String

Throws:

BadSemanticsException - if there is an element with no name

escattr

static String escattr(String s)

This function escapes non-printable characters and quotes. This is used to make printVal output DString data in the same way as the C++ version. Since Java supports Unicode, this will need to be altered if it's desired to print DString as UTF-8 or some other character encoding.

Parameters:

s - the input String.

Returns:

the escaped String.
