enter

static void enter(java.lang.String descent,
                  char lexeme,
                  int token)

Function: enter Description: Debugging routine.

leave

static void leave(java.lang.String descent,
                  char lexeme,
                  int token)

Function: leave Description: Debugging routine.

cuassert

static void cuassert(boolean expr)

Function: cuassert Description: Debugging routine. As of release 1.4, cuassert is a keyword, and may not be used as an identifier

doubleSize

static char[] doubleSize(char[] oldBuffer)

Function: doubleSize

doubleSize

static byte[] doubleSize(byte[] oldBuffer)

Function: doubleSize

hex2bin

static char hex2bin(char c)

Function: hex2bin

ishexdigit

static boolean ishexdigit(char c)

Function: ishexdigit

oct2bin

static char oct2bin(char c)

Function: oct2bin

isoctdigit

static boolean isoctdigit(char c)

Function: isoctdigit

isspace

static boolean isspace(char c)

bytencmp

static int bytencmp(byte[] a,
                    int a_first,
                    byte[] b,
                    int b_first,
                    int n)

Function: bytencmp Description: Compares up to n elements of byte array a[] against byte array b[]. The first byte comparison is made between a[a_first] and b[b_first]. Comparisons continue until the null terminating byte '\0' is reached or until n bytes are compared. Return Value: Returns 0 if arrays are the same up to and including the null terminating byte or up to and including the first n bytes, whichever comes first.

charncmp

static int charncmp(char[] a,
                    int a_first,
                    char[] b,
                    int b_first,
                    int n)

Function: charncmp
