Method Details

isEmpty

public static boolean isEmpty(String string)

Returns true if given string is null or length is zero.

removeLeading

public static String removeLeading(String string,
 String leading)

removeTrailing

public static String removeTrailing(String string,
 String trailing)

split

public static List<String> split(String str,
 char delim)

split

public static List<String> split(String str,
 char delim,
 boolean trim,
 boolean excludeEmpty)

Splits a string at the specified delimiter. If trimming is enabled, then leading and trailing whitespace characters are removed. If excludeEmpty is true, then only non-empty strings are returned.

add

private static void add(List<String> strs,
 String str,
 int beginIndex,
 int endIndex,
 boolean trim,
 boolean excludeEmpty)

substringTrimmed

public static String substringTrimmed(String str,
 int beginIndex)

This is equal to str.substring( beginIndex, endIndex ).trim(), but avoids temporary untrimmed substring allocation. If the trimmed string is empty, a shared empty string is returned.

Since:

2

substringTrimmed

public static String substringTrimmed(String str,
 int beginIndex,
 int endIndex)

This is equal to str.substring( beginIndex ).trim(), but avoids temporary untrimmed substring allocation. If the trimmed string is empty, a shared empty string is returned.

Since:

2

isTrimmedEmpty

public static boolean isTrimmedEmpty(String str)

This is equal to str.trim().isEmpty(), but avoids temporary trimmed substring allocation.

Since:

2

trimBegin

private static int trimBegin(String str,
 int beginIndex,
 int endIndex)

trimEnd

private static int trimEnd(String str,
 int beginIndex,
 int endIndex)
