Method Detail

splitCommas

public static java.util.List<java.lang.String> splitCommas(java.lang.String str)

Splits a single string into a list of strings as follows: 1) The string is split at each comma. 2) Each resulting substring is trimmed and added to the list Note that there is no way of escaping a comma within a value.

Parameters:

str - the string to be parsed

Returns:

a list of substrings

parseProperties

public static java.util.Map<java.lang.String,java.lang.String> parseProperties(java.lang.String propsStr)

Constructs a map of strings from a single string as follows: 1) The string is split at each semicolon. 2) Each component is split at a colon into a key and a value. 3) Each key-value pair is trimmed and added to the map This encoding should be superficially familiar to those familiar with CSS style properties. Note that there are no mechanisms for escaping colons and semicolons. Keys may not be duplicated.

Parameters:

propsStr - the string to be parsed

Returns:

a map of string properties

join

public static java.lang.String join(java.lang.Object[] array,
                                    java.lang.String delimiter)

Joins the string representations of an array of objects into a single string, separating them with the supplied delimiter. A zero length array results in an empty string.

Parameters:

array - the array of objects to be joined

delimiter - string to be inserted between array element

Returns:

all the elements of the array concatenated into a single string, never null
