Method Detail

splitSmart

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

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)

Parameters:

s - the string to split

separator - the separator to split on

decode - decode backslash escaping

splitFileNames

public static List<String> splitFileNames(String fileNames)

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

Parameters:

fileNames - the string containing file names

Returns:

a list of file names with the escaping backslashed removed

join

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

Creates a backslash escaped string, joining all the items.

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)

Returns:

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.

Throws:

IOException
