Method Detail

parse

public static List<MessageParamParser.MessageParamInfo> parse(String input)
                                                       throws ParseException

Splits the input string into message param informations.

The expected format is a comma separated list of index:ognlPath strings. The OGNL path may be missing, in this case the index alone.

Example: 0:user.name,4,3:user.id.

Spaces between tokens are removed.

If the input string is null or empty, the empty list is returned.

Parameters:

input - the input string to parse.

Returns:

the list of message parameter infos.

Throws:

ParseException - if the input is violating the expected syntax.

public static Map<String,List<MessageParamParser.MessageParamInfo>> parseParentMessageParam(String input)
                                                                                     throws ParseException

Parses the content of the parent message parameter. The input must follow the following syntax:

property=index:ognl-path as in cause=1:message

If several properties of a referenced entity are to be displayed at different indices, separate them by commas and the information for different attributes separate by colons (;).

cause=1:cause.message,3:message,4:localizedMessage; message=5

Parameters:

input - the input string to parse.

Returns:

the parsed information. The key of the map is the name of the attribute, the value is the index information for that attribute.
