 boolean delim)

Convert the byte array to a character string.

Parameters:

buf - byte array to be converted.

start - starting offset into byte array for conversion.

len - number of bytes to convert.

delim - true if conversion should terminate on meeting a Reality system delimiter (SVM | VM | AM | SM).

Returns:

converted string.

---

public java.lang.String toString(byte[] buf,
 int start,
 int len)

Convert the byte array to a character string.

Parameters:

buf - byte array to be converted.

start - starting offset into byte array for conversion.

len - number of bytes to convert.

Returns:

converted string.

---

getIndex

public int getIndex(byte[] buf,
 int start,
 int len,
 int num,
 int delim)

Find the n'th occurrence of the delimiter in the byte array.

Parameters:

buf - byte array to be converted.

start - starting offset into byte array for conversion.

len - number of bytes to scan.

num - number of delimiters to skip.

delim - true if conversion should terminate on meeting a Reality system delimiter (SVM | VM | AM | SM).

Returns:

index to delimiter if found; else -1.
