Parameters:   str - The string to be split. Parameters:   delimiter - Split string based on this delimiter. Array of split strings. public static  String[] splitString(String str, char delimiter, boolean removeEmpty)      Split a string based on the given delimiter, optionally removing empty elements. Parameters:   str - The string to be split. Parameters:   delimiter - Split string based on this delimiter. Parameters:   removeEmpty - If true then remove empty elements. Array of split strings. Method Detail areStringsEqual public static boolean areStringsEqual(String s1, String s2)(Code) Return whether the 2 passed strings are equal. This function allows for null strings. If s1 and s1 are both null they are considered equal. changeClassNameToFileName public static String changeClassNameToFileName(String name)(Code) Change the passed class name to its corresponding file name. E.G. change "Utilities" to "Utilities.class". Parameters:   name - Class name to be changed. throws:   IllegalArgumentException - If a null name passed. changeFileNameToClassName public static String changeFileNameToClassName(String name)(Code) Change the passed file name to its corresponding class name. E.G. change "Utilities.class" to "Utilities". Parameters:   name - Class name to be changed. If this does not representa Java class then null is returned. throws:   IllegalArgumentException - If a null name passed. cleanString public static String cleanString(String str)(Code) Clean the passed string. Replace whitespace characters with a single space. If a null string passed return an empty string. E.G. replace [pre] \t\tselect\t* from\t\ttab01 [/pre] with [pre] select * from tab01 [/pre] Parameters:   str - String to be cleaned. Cleaned string. cloneObject public static Object cloneObject(Object toClone, ClassLoader classLoader)(Code) Creates a clone of any serializable object. Collections and arrays may be cloned if the entries are serializable. Caution super class members are not cloned if a super class is not serializable. closeReader public static void closeReader(Reader reader)(Code) Closes the specified Reader which can be null. Logs an error if an exception occurs while closing. Parameters:   reader - the Reader to close. formatSize public static String formatSize(long longSize)(Code) formatSize public static String formatSize(long longSize, int decimalPos)(Code) getDeepestThrowable public static Throwable getDeepestThrowable(Throwable t)(Code) getFileNameSuffix public static String getFileNameSuffix(String fileName)(Code) Return the suffix of the passed file name. Parameters:   fileName - File name to retrieve suffix for. Suffix for fileName or an empty stringif unable to get the suffix. throws:   IllegalArgumentException - if null file name passed. getStackTrace public static String getStackTrace(Throwable th)(Code) Return the stack trace from the passed exception as a string Parameters:   th - The exception to retrieve stack trace for. isStringEmpty public static boolean isStringEmpty(String str)(Code) Return true if the passed string is null or empty. Parameters:   str - String to be tested. true if the passed string is null or empty. printStackTrace public static void printStackTrace(PrintStream ps)(Code) Print the current stack trace to ps. Parameters:   ps - The PrintStream to print stack trace to. throws:   IllegalArgumentException - If a null ps passed. removeFileNameSuffix public static String removeFileNameSuffix(String fileName)(Code) Remove the suffix from the passed file name. Parameters:   fileName - File name to remove suffix from. fileName without a suffix. throws:   IllegalArgumentException - if null file name passed. replaceI18NSpanLine public static String replaceI18NSpanLine(String line, StringManager s_stringMgr)(Code) Internationalizes a line with an embedded I18n key in it. Suppose that the line looks like: This is a line with a embeddedKey in it. Further suppose the our I18NStrings.properties has the line: embeddedKey=(string that all would like to read) This method will return the value: This is a line with a (string that all would like to read) in it. Note: This method cannot currently handle more than one embedded I18n string in the specified line at this time. Please put multiple keys on separate lines. Otherwise, truncation of the specified line could result! Parameters:   line - the line to internationalize Parameters:   s_stringMgr - the StringManager to use to lookup I18N keys. an internationalized replacement for this line splitString public static String[] splitString(String str, char delimiter)(Code) Split a string based on the given delimiter, but don't remove empty elements. Parameters:   str - The string to be split. Parameters:   delimiter - Split string based on this delimiter. Array of split strings. Guaranteeded to be not null. splitString public static String[] splitString(String str, char delimiter, boolean removeEmpty)(Code) Split a string based on the given delimiter, optionally removing empty elements. Parameters:   str - The string to be split. Parameters:   delimiter - Split string based on this delimiter. Parameters:   removeEmpty - If true then remove empty elements. Array of split strings.
