makeFilePath

public static String makeFilePath(String[] strings,
                                  boolean addTrailing)

A utility to get the Operating System specific path from given array of Strings.

Parameters:

strings - an array of Strings participating in the path.

addTrailing - a boolean that determines whether the returned String should have a trailing File Separator character. None of the strings may be null or empty String. An exception is thrown.

Returns:

a String that concatenates these Strings and gets a path. Returns a null if the array is null or contains no elements.

Throws:

IllegalArgumentException - if any of the arguments is null or is an empty string.

parseStringList

public static List<String> parseStringList(String line)

Parses a string containing substrings separated from each other by the standard separator characters and returns a list of strings. Splits the string line into individual string elements separated by the field separators, and returns these individual strings as a list of strings. The individual string elements are trimmed of leading and trailing whitespace. Only non-empty strings are returned in the list.

Parameters:

line - The string to split

Returns:

Returns the list containing the individual strings that the input string was split into.

parseStringList

public static List<String> parseStringList(String line,
                                           String sep)

Parses a string containing substrings separated from each other by the specified set of separator characters and returns a list of strings. Splits the string line into individual string elements separated by the field separators specified in sep, and returns these individual strings as a list of strings. The individual string elements are trimmed of leading and trailing whitespace. Only non-empty strings are returned in the list.

Parameters:

line - The string to split

sep - The list of separators to use for determining where the string should be split. If null, then the standard separators (see StringTokenizer javadocs) are used.

Returns:

Returns the list containing the individual strings that the input string was split into.

getProperty

public static String getProperty(String propName)

Get a system propety given a property name, possibly trying all combination of upercase, name mangling to get a value.

Parameters:

propName - the approximate system property name

Returns:

the property value if found, null otherwise

removeChar

public static String removeChar(String strOrig,
                                char c)

Remove a character from a String

Parameters:

strOrig - original string

c - character to remove from the string

Returns:

String with specified characters removed

getStackTrace

public static String getStackTrace(Throwable t)

isToken

public static final boolean isToken(String s)

stripToken

public static final String stripToken(String s)

cat

public static String cat(String separator,
                         String... list)

Concatenate a list of strings, putting a separator in between each one. If the list is one string, then the separator is not used. The separator will never be added to the start or end of the returned string. When empty or null strings are encountered in the list of strings they are ignore.

Parameters:

separator - Separator to use between concatenated strings

list - List of strings to concatenate together

Returns:

String created by concatenating provided strings

removeEnclosingQuotes

public static String removeEnclosingQuotes(String s)

Removes the quoting around a String.

Parameters:

s - The String that may have enclosing quotes

Returns:

The String resulting from removing the enclosing quotes

quotePathIfNecessary

public static String quotePathIfNecessary(String path)

Nightmares can result from using a path with a space in it! This method will enclose in quotes if needed.

Parameters:

path -

Returns:
