public class StringPool

extends java.lang.Object

Class name: StringPool Class description: This class is only for the easy operation of formit and webgate, since it's heavily used in the original system, we'd better keep it here otherwise significant modification will be needed to handle html format. But some function/methods are added to reduce coupling between different classes Author: Jianxin Zhao Finished time: June 4, 1998 Known bugs: none Platform: jdk1.1.5 under UNIX

Constructor Summary

StringPool(edu.vt.marian.common.Debug debug)
This constructor just create an empty string pool

StringPool(java.io.InputStream is, edu.vt.marian.common.Debug debug)
This constructor will create a string pool object from a stream, this is a new method added to this class

StringPool(packet_input_stream pis, edu.vt.marian.common.Debug debug)
This constructor will create a string pool object from a stream, this is a new method added to this class

Method Summary

void	AddCGIData(java.lang.String data) This method will add the cgi data to the string pool, it will first decode special chars like '+', '%', '&' then add the strings seperated by them to the string pool I believe this method reduced the coupling between different classes
void	AddString(java.lang.String s) This method will add the string to the string pool
void	AddSubString(java.lang.String s) This method will add part of the string (strings between data seperaters) into the string pool
void	AddValue(java.lang.String name, java.lang.String value) This method will add the name value pair to the string pool, this method and the method GetValue will make handling cgi data easy
void	DeleteString(int num) This method will delete the numth string from the string pool.
java.util.Vector	get_names() this method will return the name list in this object
java.util.Vector	get_names(java.lang.String value) this method will return the name list in this object which have the specified value
int	GetHexValue(java.lang.String digits) This method will return the hex value of the parameter digits, -1 will be returned if digits is not a valid hex digit string, by using ...length() insteadof 16 we improve the function's flexibility.
int	GetNumLines(int num) This method will return the number of lines in the numth string of the string pool
int	GetNumStrings() This method will return the number of strings currently exist in the string pool
java.lang.String	GetString(int num) This method will return the numth string currently in the string pool, null will be returned if the num is out of bound
java.lang.String	GetValue(java.lang.String name) This method will return the value of the name in the string pool, null will be returned if no such value exist in the string pool
void	to_stream(packet_output_stream pos) This method will print the content of this string pool object to a stream this method can be used with the above constructor in network environment
void	to_stream(java.io.PrintWriter pw) This method will print the content of this string pool object to a stream this method can be used with the above constructor in network environment
void	toStream(java.io.OutputStream os) This method will print the content of this string pool object to a stream this method can be used with the above constructor in network environment

AddString

public void AddString(java.lang.String s)

This method will add the string to the string pool

AddSubString

public void AddSubString(java.lang.String s)

This method will add part of the string (strings between data seperaters) into the string pool

AddValue
