Field Detail

### LINE_SEP

    public static final java.lang.String LINE_SEP

  the line separator for this OS

Method Detail

### lineSplit

    public static java.util.Vector lineSplit(java.lang.String data)

  Splits up a string into a list of lines. It is equivalent to `split(data, '\n')`.

  Parameters:
    `data` - the string to split up into lines.
  Returns:
    the list of lines available in the string.

### split

    public static java.util.Vector split(java.lang.String data,
                                         int ch)

  Splits up a string where elements are separated by a specific character and return all elements.

  Parameters:
    `data` - the string to split up.
    `ch` - the separator character.
  Returns:
    the list of elements.

### replace

    public static java.lang.String replace(java.lang.String data,
                                           java.lang.String from,
                                           java.lang.String to)

  Replace occurrences into a string.

  Parameters:
    `data` - the string to replace occurrences into
    `from` - the occurrence to replace.
    `to` - the occurrence to be used as a replacement.
  Returns:
    the new string with replaced occurrences.

### getStackTrace

    public static java.lang.String getStackTrace(java.lang.Throwable t)

  Convenient method to retrieve the full stacktrace from a given exception.

  Parameters:
    `t` - the exception to get the stacktrace from.
  Returns:
    the stacktrace from the given exception.

### endsWith

    public static boolean endsWith(java.lang.StringBuffer buffer,
                                   java.lang.String suffix)

  Checks that a string buffer ends up with a given string. It may sound trivial with the existing JDK API but the various implementation among JDKs can make those methods extremely resource intensive and perform poorly due to massive memory allocation and copying. See

  Parameters:
    `buffer` - the buffer to perform the check on
    `suffix` - the suffix
  Returns:
    `true` if the character sequence represented by the argument is a suffix of the character sequence represented by the StringBuffer object; `false` otherwise. Note that the result will be `true` if the argument is the empty string.

### resolveBackSlash

    public static java.lang.String resolveBackSlash(java.lang.String input)

  xml does not do "c" like interpretation of strings. i.e. \n\r\t etc. this method processes \n, \r, \t, \f, \\ also subs \s -> " \n\r\t\f" a trailing '\' will be ignored

  Parameters:
    `input` - raw string with possible embedded '\'s
  Returns:
    converted string
  Since:
    Ant 1.7

### parseHumanSizes

    public static long parseHumanSizes(java.lang.String humanSize)
                                throws java.lang.Exception

  Takes a human readable size representation eg 10K a long value. Doesn't support 1.1K or other rational values.

  Parameters:
    `humanSize` -
  Returns:
    a long value representation
  Throws:
    `java.lang.Exception`
  Since:
    Ant 1.7
