isMatch

public static boolean isMatch(String s,
                              String p)

 '?' Matches any single character.
 '*' Matches any sequence of characters (including the empty sequence).

 isMatch("aa","a")       = false
 isMatch("aa","aa")      = true
 isMatch("aaa","aa")     = false
 isMatch("aa", "*")      = true
 isMatch("aa", "a*")     = true
 isMatch("ab", "?*")     = true
 isMatch("aab", "c*a*b") = false
 

参数:

s - the text

p - the wildcard pattern

返回:

true if the string match pattern

toSeparatedFormat

public static String toSeparatedFormat(String camelcaseFormat,
                                       char separator)

驼峰转为带分隔符名字，如驼峰转换为下划线：CaseFormat.LOWER_CAMEL.to(CaseFormat.LOWER_UNDERSCORE, camelCaseName);

参数:

camelcaseFormat - the camelcase format

separator - the separator character

返回:

separator format string

另请参阅:

CaseFormat.to(CaseFormat, String)

toCamelCaseFormat

public static String toCamelCaseFormat(String separatedFormat,
                                       char separator)

带分隔符名字转驼峰，如下划线转换为驼峰：CaseFormat.LOWER_UNDERSCORE.to(CaseFormat.LOWER_CAMEL, underscoreName);

 1、LOWER_HYPHEN      ->  连字符的变量命名规范如lower-hyphen
 2、LOWER_UNDERSCORE  ->  c++变量命名规范如lower_underscore
 3、LOWER_CAMEL       ->  java变量命名规范如lowerCamel
 4、UPPER_CAMEL       ->  java和c++类的命名规范如UpperCamel
 5、UPPER_UNDERSCORE  ->  java和c++常量的命名规范如UPPER_UNDERSCORE
 

参数:

separatedFormat - the separated format

separator - the separator character

返回:

camelcase format string

另请参阅:

CaseFormat.to(CaseFormat, String)

requireNonBlank

public static String requireNonBlank(String str)

of

withSuffix

public static String withSuffix(String str,
                                String suffix)

trimPath

public static String trimPath(String path)

Returns trim path.

  trimPath("test///")          = "/test"
  trimPath("test/abc///")      = "/test/abc"
  trimPath(" /test/abc/// ")   = "/test/abc"
  trimPath(" / // /// ")       = "/"
  trimPath(" /test/abc/ / / ") = "/test/abc"
 

参数:

path - the path

返回:

trim path

concatPath

public static String concatPath(String prefixPath,
                                String suffixPath)

拼接两个路径，以“/”开头，不以“/”结尾

e.g.: concatPath("/a", "/b/c") -> /a/b/c

参数:

prefixPath - the prefix path

suffixPath - the suffix path

返回:

concat path

substringAfterLast

public static String substringAfterLast(String str,
                                        String separator)

  substringAfterLast(null, ".")      = null
  substringAfterLast("", ".")        = ""
  substringAfterLast("abc", ".")     = "abc"
  substringAfterLast("abc.def", ".") = "def"
