Parameters:
item - byte array holding the reality item to be viewed

RealItemTokenizer

public RealItemTokenizer(byte[] item,
 byte del)
Create a new item view with user defined delimiter

Parameters:
item - byte array holding the reality item to be viewed
del - byte containing first level delimiter

RealItemTokenizer

public RealItemTokenizer(byte[] itm,
 byte del1,
 byte del2,
 byte del3)
Create a new item view with user defined delimiters

Parameters:
item - byte array holding the reality item to be viewed

del3 - byte containing third level delimiter

Method Detail

toString

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

toString

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.
