                                          java.lang.String replacement)

Deprecated. (Generates too much garbage)

Replaces all the occurences of a substring found within a string by a replacement string

Parameters:

original - the string in where the replace will take place

find - the substring to find and replace

replacement - the replacement string for all occurences of find

Returns:

the original string where all the occurences of find are replaced by replacement

replaceAll

public static java.lang.StringBuffer replaceAll(java.lang.StringBuffer buffer,
                                                java.lang.String find,
                                                java.lang.String replacement)

Replaces all the occurences of a substring found within a StringBuffer by a replacement string

Parameters:

buffer - the StringBuffer in where the replace will take place

find - the substring to find and replace

replacement - the replacement string for all occurences of find

Returns:

the original StringBuffer where all the occurences of find are replaced by replacement

arrayToString

public static final java.lang.String arrayToString(java.lang.String[] array,
                                                   java.lang.String separators)

Takes an array of tokens and converts into separator-separated string.

Returns:

String A string containing tokens separated by seperator.

stringToArray

public static final java.lang.String[] stringToArray(java.lang.String str,
                                                     java.lang.String separators)

Converts a delimited string into an array of string tokens.

Returns:

String A string array of the original tokens.

removeChars

public static java.lang.String removeChars(java.lang.String data,
                                           java.lang.String removeChars)

Remove a given set of characters from a String.

Returns:

String The new string cleansed of 'removeChars'.

stripExtension

public static java.lang.String stripExtension(java.lang.String filename)

replaceVars

public static java.lang.String replaceVars(java.lang.String origString,
                                           java.util.Map vars)

Performs variable substitution for a string. String is scanned for ${variable_name} and if one is found, it is replaced with corresponding value from the vars hashtable.

Parameters:

origString - unmodified string

vars - Hashtable of replacement values

Returns:

modified string

Throws:

java.lang.Exception

splitString

public static java.util.ArrayList splitString(java.lang.String list,
