org.vmdb.hl7
Class StringList  

java.lang.Object
  org.vmdb.hl7.StringList

All Implemented Interfaces:

java.io.Serializable

---

public class StringList

extends java.lang.Object

implements java.io.Serializable

String List Modified String Tokenizer.

Description: HL7 Network Connectivity For VMDB.

Copyright: Copyright (c) 2002-2003.

Company: M&M Informatics.

More or less take over from the StringTokenizer class but with two modifications. First, two sequential tokens result in an empty string rather than no token. Second getIndex and setIndex allow saving and restoring state to allow roll-back of reading from the list.

Version:

1.0

Field Summary
private  int	iCurIndex
static char	NONE           NULL character used to specify no escape character.
private  java.util.Vector	vData

 

Constructor Summary

StringList(java.io.Reader rData, char cDelimiter)           Construct a string list, splitting the data string with the delimiter character.

StringList(java.lang.String sData, char cDelimiter)           Construct a string list, splitting the data string with the delimiter character.

 

Method Summary
int	getIndex()           Get the current location of the string retrieval pointer as an integer. This can be saved and used later to undo a number of nextString() calls.
boolean	hasMoreStrings()           Test list for existence of one or more remaining tokens.
void	init(java.io.Reader rData, char cDelimiter)           Populate this string list, splitting the data string with the delimiter character.
void	init(java.lang.String sData, char cDelimiter)           Populate this string list, splitting the data string with the delimiter character.
java.lang.String	nextString()           Get the next string from the list of tokenized strings.
void	setIndex(int iCurIndex)           Return the current location pointer to a saved location.
int	size()           Return the number of strings in the tokenized list.
java.lang.String	toString()           This is mostly a debugging method.
boolean	undoNext()           Move the pointer back one, having the effect of putting the last string retrieved back onto the list.

                  char cDelimiter)

Construct a string list, splitting the data string with the delimiter character.

---

StringList

public StringList(java.io.Reader rData,
                  char cDelimiter)

Construct a string list, splitting the data string with the delimiter character.

Method Detail

init

public void init(java.lang.String sData,
                 char cDelimiter)

Populate this string list, splitting the data string with the delimiter character.

---

init

public void init(java.io.Reader rData,
                 char cDelimiter)

Populate this string list, splitting the data string with the delimiter character.

---

toString

public java.lang.String toString()

This is mostly a debugging method. It converts the string list to one line per token format.

---

hasMoreStrings

public boolean hasMoreStrings()

Test list for existence of one or more remaining tokens.

---

nextString

public java.lang.String nextString()

Get the next string from the list of tokenized strings.

---

undoNext

public boolean undoNext()

Move the pointer back one, having the effect of putting the last string retrieved back onto the list.

---

size

public int size()

Return the number of strings in the tokenized list.

---

getIndex

public int getIndex()

Get the current location of the string retrieval pointer as an integer.

This can be saved and used later to undo a number of nextString() calls. The effect is of bookmarking a location.

---

setIndex

public void setIndex(int iCurIndex)

Return the current location pointer to a saved location.
