public class SETutils

extends Object

SETutils()

getChildren(Element)

Methods that takes an XML4J/DOM element and returns its children, ignoring whitespaces between tags

hasher(Document, String)

hasher(String, String)

Method that implements a hashing algorithm (MD5 or SHA-1).

numChildren(Element)

Method to take an XML4J DOM element and count its number of children Whitespaces here are not ignored.

parseFile(String)

Method that packages up a file into an inputstream

printElement(Element)

Simplistic method to print out an element with its immediate children

queryMax(Vector, String)

Method that returns the desired document or tags that represents the maximum value in a given tag.

queryMin(Vector, String)

Method that returns the desired document or tags that represents the minimum value in a given tag.

stringMaxMin(Vector, int)

Method that rerturns the min or max string from a vector of strings

writeServiceEntry(String, ServiceEntry)

void writeServiceEntry(String, ServiceEntry) ** Method that takes in a ServiceEntry, and writes it to a specified filename, writing out the fields in this order:
1.

 public SETutils()

 public static Vector queryMax(Vector xmlVector,
                               String rangeTag)

Method that returns the desired document or tags that represents the maximum value in a given tag. Just a wrapper for queryMaxMin

Parameters:

xmlVector - The vector of XML documents to be compared

rangeTag - The string name of the tag the max is executed on

Returns:

vector of simple xml documents as strings

 public static Vector queryMin(Vector xmlVector,
                               String rangeTag)

Method that returns the desired document or tags that represents the minimum value in a given tag. Just a wrapper for queryMaxMin

Parameters:

xmlVector - The vector of XML documents to be compared

rangeTag - The string name of the tag the min is executed on

Returns:

vector of simple xml documents as strings

 public static String stringMaxMin(Vector stringV,
                                   int maxmin)

Method that rerturns the min or max string from a vector of strings

Parameters:

stringV - the vector of strings that we take the max or min from

maxmin, - indicator of max or min, if <0 min, if >0 max, if 0 null

Returns:

string that is the end result value as the max or min

 public static void writeServiceEntry(String fileName,
                                      ServiceEntry se) throws RecoveryException

void writeServiceEntry(String, ServiceEntry) ** Method that takes in a ServiceEntry, and writes it to a specified filename, writing out the fields in this order:
1. String ID (SHA-1 Hash of contents)
2. Heart beat
3. XML description in String

The fields are written out separated by newlines, and the sequence number (numerical ID) is not written, since it is embedded in the filename.

If the file exists, it is not overwritten

Parameters:

fileName - Name of the file to be written out

content - The string contents of the file

Throws: thrown

when IOException hit or trying to write paged out entry

 public static int numChildren(Element e)

Method to take an XML4J DOM element and count its number of children Whitespaces here are not ignored. For that value, do getChildren().size()

Parameters:

e - The DOM element in question

Returns:

integer that represents the number of children it has

 public static Vector getChildren(Element e)

Methods that takes an XML4J/DOM element and returns its children, ignoring whitespaces between tags

Parameters:

e - The DOM element that we find nonwhitespace children for

Returns:

Vector containing the child DOM elements

 public static void printElement(Element n)

Simplistic method to print out an element with its immediate children

 public static InputStream parseFile(String f) throws FileNotFoundException

Method that packages up a file into an inputstream

 public static String hasher(String inString,
                             String alg) throws NoSuchAlgorithmException

Method that implements a hashing algorithm (MD5 or SHA-1). Takes in a string and returns a string that represented the hashed value.

Parameters:

inString - The input that is to be hashed

alg - The algorithm to be used, either "MD5" or "SHA-1"

Returns:

the hashed value of inString

Throws: NoSuchAlgorithmException

thrown when algorithm is unknown

 public static String hasher(Document d,
                             String alg) throws NoSuchAlgorithmException
