Usage

From source file:de.innovationgate.utils.WGUtils.java

/**
 * Creates a List based on string, that contains substring tokens divided by a
 * special divider string. Can be used to recreate lists that were
 * serialized by//from   w ww .j ava  2s .c  o m
 * {@link #serializeCollection serializeCollection}.
 * 
 * This command: WGUtils.deserializeCollection("a;b;c", ";")
 * 
 * Would create a list containing the three strings "a", "b" and "c".
 * 
 * 
 * @param colString
 *            The string that contains the list information
 * @param divider
 *            divider string that separates the substrings.
 * @param trimTokens
 *            Decides if the tokens are trimmed (via String.trim())
 *            before they are put into the list
 * @param stringDelimiter
 *            Describes a character that should be treated as string
 *            delimiter, like " or '. Text contained in these signs will be
 *            ignored when the split operation is done. Use null if you do
 *            not want to ignore strings.
 * @param removeTokenStringDelimiter
 *            If true and a string delimiter was given will remove delimiters that wrap whole tokens on output. So input string "'a','b'" will return strings "a" and "b" on deserialisation if the ' character was given as delimiter. 
 * @return A list consisting of the substrings inside the parameter string.
 *         Divider strings are omitted.
