方法详细资料

splitSmart

public static List<String> splitSmart(String s,
                                      char separator)

split

public static List<String> split(String s,
                                 char sep)

splitSmart

public static List<String> splitSmart(String s,
                                      char separator,
                                      boolean trimEmpty)

splitSmart

public static void splitSmart(String s,
                              char separator,
                              List<String> lst)

Split a string based on a separator, but don't split if it's inside a string. Assume '\' escapes the next char both inside and outside strings.

splitSmart

public static List<String> splitSmart(String s,
                                      String separator,
                                      boolean decode)

Splits a backslash escaped string on the separator.

Current backslash escaping supported:
\n \t \r \b \f are escaped the same as a Java String
Other characters following a backslash are produced verbatim (\c => c)

参数:

s - the string to split

separator - the separator to split on

decode - decode backslash escaping

返回:

not null

splitFileNames

public static List<String> splitFileNames(String fileNames)

Splits file names separated by comma character. File names can contain comma characters escaped by backslash '\'

参数:

fileNames - the string containing file names

返回:

a list of file names with the escaping backslashed removed

join

public static String join(Collection<?> items,
                          char separator)

Creates a backslash escaped string, joining all the items.

escapeTextWithSeparator(java.lang.String, char)

splitWS

public static List<String> splitWS(String s,
                                   boolean decode)

toLower

public static List<String> toLower(List<String> strings)

parseBoolean

public static boolean parseBoolean(String s)

Return if a string starts with '1', 't', or 'T' and return false otherwise.

parseBool

public static boolean parseBool(String s)

how to transform a String into a boolean... more flexible than Boolean.parseBoolean() to enable easier integration with html forms.

parseBool

public static boolean parseBool(String s,
                                boolean def)

NullPointerException and SolrException free version of parseBool(String)

返回:

parsed boolean value (or def, if s is null or invalid)

partialURLEncodeVal

public static void partialURLEncodeVal(Appendable dest,
                                       String val)
                                throws IOException

URLEncodes a value, replacing only enough chars so that the URL may be unambiguously pasted back into a browser.

Characters with a numeric value less than 32 are encoded. &,=,%,+,space are encoded.

抛出:

IOException

escapeTextWithSeparator

public static String escapeTextWithSeparator(String item,
                                             char separator)

Creates a new copy of the string with the separator backslash escaped.

join(java.util.Collection<?>, char)

appendEscapedTextToBuilder

public static void appendEscapedTextToBuilder(StringBuilder out,
                                              String item,
                                              char separator)

writes chars from item to out, backslash escaping as needed based on separator -- but does not append the separator itself

formatString

public static String formatString(String pattern,
                                  Object... args)

Format using MessageFormat but with the ROOT locale
