wwUtils::TokenizeString
wwUtils::TokenizeString
String tokenizing function that extracts and replaces tokens found by extracting value between a start and end delimiter. The extracted values are returned in a sequential collection.
If the source is passed by reference the source is modified with a tokenized placeholder.
Tokenized strings look like this (#@# delimiter): IEnumerable#@#1#@# List, Field field, List#@#2#@# fieldList
o.TokenizeString(@lcSource,lcStart,lcEnd,lcDelimiter)
Parameters
@lcSource
The input string that is to be tokenized. Pass by reference if you want to receive back the string with the tokens embedded.
lcStart
A starting search string which is extracted for a token.
lcEnd
An end search string which is extracted for a token.
lcDelimiter
Optional - delimiter for embedded tokens. The default is #@#.
String tokens are embedded in the format (based on #@# delimiter):
Some text #@#1#@# some other text #@#2#@#.
Example
lcParameters = "IEnumerable<Field,bool> List, Field field, List<Field,int> fieldList"
? "Original: "
? lcParameters
?
*** Creates tokens in the lcSource String and returns a collection of the
*** tokens.
loTokens = TokenizeString(@lcParameters,"<",">")
? lcParameters
* IEnumerable#@#1#@# List, Field field, List#@#2#@# fieldList
FOR lnX = 1 TO loTokens.Count
? loTokens[lnX]
ENDFOR
?
? "Tokenized string: " + lcParameters
?
? "Parsed parameters:"
*** Now parse the parameters
lnCount = ALINES(laParms,lcParameters,",")
FOR lnX = 1 TO lnCount
*** Detokenize indvidual parameters
laParms[lnX] = DetokenizeString(laParms[lnX],loTokens)
? laParms[lnX]
ENDFOR
?
? "Detokenized String (should be same as original):"
*** or you can detokenize the entire string at once
? DetokenizeString(lcParameters,loTokens)
