java.lang.Objectorg.apache.jorphan.util.JOrphanUtils
This class contains frequently-used static utility methods.
| Method Summary | |
static String |
baToHexString(byte[] ba)
Convert binary byte array to hex string. |
static String |
booleanToSTRING(boolean value)
Convert a boolean to its string representation Equivalent to Boolean.valueOf(boolean).toString().toUpperCase() but valid also for JDK 1.3, which does not have valueOf(boolean) |
static void |
closeQuietly(InputStream is)
close a stream with no error thrown |
static void |
closeQuietly(OutputStream os)
close a stream with no error thrown |
static void |
closeQuietly(Reader rd)
close a Reader with no error thrown |
static void |
closeQuietly(ServerSocket sock)
close a Socket with no error thrown |
static void |
closeQuietly(Socket sock)
close a Socket with no error thrown |
static void |
closeQuietly(Writer wr)
close a Writer with no error thrown |
static byte[] |
getByteArraySlice(byte[] array,
int begin,
int end)
Returns a slice of a byte array. |
static boolean |
isXML(byte[] target)
Detects if some content starts with the standard XML prefix. |
static StringBuffer |
leftAlign(StringBuffer in,
int len)
Left aligns some text in a StringBuffer N.B. modifies the input buffer |
static String |
replaceAllChars(String source,
char search,
String replace)
Version of String.replaceAll() for JDK1.3 See below for another version which replaces strings rather than chars |
static String |
replaceFirst(String source,
String search,
String replace)
Simple-minded String.replace() for JDK1.3 Should probably be recoded... |
static StringBuffer |
rightAlign(StringBuffer in,
int len)
Right aligns some text in a StringBuffer N.B. modifies the input buffer |
static String[] |
split(String splittee,
String splitChar)
|
static String[] |
split(String splittee,
String splitChar,
boolean truncate)
This is _almost_ equivalent to the String.split method in JDK 1.4. |
static String[] |
split(String splittee,
String delims,
String def)
Takes a String and a tokenizer character string, and returns a new array of strings of the string split by the tokenizer character(s). |
static boolean |
startsWith(byte[] target,
byte[] search,
int offset)
Check if a byte array starts with the given byte array. |
static String |
substitute(String input,
String pattern,
String sub)
Replace all patterns in a String |
static String |
trim(String input,
String delims)
Trim a string by the tokens provided. |

| Method Detail |
public static String[] split(String splittee,
String splitChar,
boolean truncate)
This piece of code used to be part of JMeterUtils, but was moved here because some JOrphan classes use it too.
splittee - String to be splitsplitChar - Character(s) to split the string on, these are treated as a single unittruncate - Should adjacent and leading/trailing splitChars be removed?
split(String, String, String)
public static String[] split(String splittee,
String splitChar)
public static String[] split(String splittee,
String delims,
String def)
splittee - String to be split.delims - Delimiter character(s) to split the string ondef - Default value to place between two split chars that have
nothing between them. If null, then ignore omitted elements.
NullPointerException - if splittee or delims are nullsplit(String, String, boolean),
This is a rewritten version of JMeterUtils.split()
public static StringBuffer rightAlign(StringBuffer in,
int len)
in - StringBuffer containing some textlen - output length desired
public static StringBuffer leftAlign(StringBuffer in,
int len)
in - StringBuffer containing some textlen - output length desired
public static String booleanToSTRING(boolean value)
value - boolean to convert
public static String replaceFirst(String source,
String search,
String replace)
source - input stringsearch - string to look for (no regular expressions)replace - string to replace the search string
public static String replaceAllChars(String source,
char search,
String replace)
source - input stringsearch - char to look for (no regular expressions)replace - string to replace the search string
public static String substitute(String input,
String pattern,
String sub)
input - - string to be transformedpattern - - pattern to replacesub - - replacement
- JDK1.4 only
public static String trim(String input,
String delims)
input - string to trimdelims - list of delimiters
public static byte[] getByteArraySlice(byte[] array,
int begin,
int end)
array - -
input arraybegin - -
start of sliceend - -
end of slice
public static void closeQuietly(InputStream is)
is - - InputStream (may be null)public static void closeQuietly(OutputStream os)
os - - OutputStream (may be null)public static void closeQuietly(Writer wr)
wr - - Writer (may be null)public static void closeQuietly(Reader rd)
rd - - Reader (may be null)public static void closeQuietly(Socket sock)
sock - - Socket (may be null)public static void closeQuietly(ServerSocket sock)
sock - - ServerSocket (may be null)
public static boolean startsWith(byte[] target,
byte[] search,
int offset)
target - array to scansearch - array to search foroffset - starting offset (>=0)
String.startsWith(String, int)public static boolean isXML(byte[] target)
target - the content to check
public static String baToHexString(byte[] ba)
ba - input binary byte array
