endsWith
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 onsuffix- the suffix- Returns:
trueif the character sequence represented by the argument is a suffix of the character sequence represented by the StringBuffer object;falseotherwise. Note that the result will betrueif the argument is the empty string.

resolveBackSlash
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
Takes a human readable size representation eg 10K a long value. Doesn't support 1.1K or other rational values.- Parameters:
humanSize- the amount as a human readable string.- Returns:
- a long value representation
- Throws:
Exception- if there is a problem.- Since:
- Ant 1.7
