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 StringBuilder |
leftAlign(StringBuilder in,
int len)
Left aligns some text in a StringBuilder 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 StringBuilder |
rightAlign(StringBuilder in,
int len)
Right aligns some text in a StringBuilder 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.
|
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 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()
