Method Detail

concat

public static String concat(Object[] objects)

Concatenate the strings resulting from calling String.valueOf(Object) on each element of an array of objects. Passing a zero length array will result in the empty string being returned.

Parameters:

objects - the array of objects to be processed.

Returns:

the concatenation of the return values from calling String.valueOf on each element of objects.

Throws:

NullPointerException - if objects is null.

getHostName

public static String getHostName()
                          throws UnknownHostException

Return the local hostname.

Returns:

the local hostname.

Throws:

UnknownHostException - if no IP address for the local host could be found.

stringLiteral

public static String stringLiteral(String string)

Returns a String whose characters, if parsed by a ConfigurationFile, would yield a String equivalent to the passed argument. This is done by replacing CR and LF with their escape codes, quoting '\' and '"' with '\', and enclosing the entire sequence in double quotes. Additionally the tab, form feed, and backspace characters will be converted to their escape codes and other control characters (besides CR and LF) to octal escapes for better readability if the string is printed for debugging purposes.

Parameters:

string - the string to turn into a string literal

Returns:

a String that if parsed as sequence of of characters by ConfigurationFile would yield a String equivalent to string

Throws:

NullPointerException - if string is null
