Class TokenizedStringParameterDecoder

java.lang.Object
  org.milyn.cdr.ParameterDecoder
      org.milyn.cdr.TokenizedStringParameterDecoder

All Implemented Interfaces:

ContentHandler

public class TokenizedStringParameterDecoder
extends ParameterDecoder

ParameterDecoder used to tokenize a parameter values into a List or HashSet.

Tokenizes parameter values into a List (param-type="string-list") or HashSet (param-type="string-hashset") using StringTokenizer.

Two default configurations of this decoder are pre-installed for all profiles. They're named "string-list" and "string-hashset".

Example Usage

The following example illustrates use of the pre-installed "string-hashset" decoder:

Configuration:

 <resource-config target-profile="html4" selector="XXX">
      <resource>com.acme.XXXContentDeliveryUnit</resource>
      <param name="blockLevelElements" type="string-hashset">
          p,h1,h2,h3,h4,h5,h6,div,ul,ol,dl,menu,dir,pre,hr,blockquote,address,center,noframes,isindex,fieldset,table
      </param>
 </resource-config>

Usage:
... and "com.acme.XXXContentDeliveryUnit" accesses this parameter value as follows:

 Parameter param = resourceConfig.getParameter("blockLevelElements");
 HashSet blockLevelElements = (HashSet)param.getValue(ContentDeliveryConfig); 
 

Note, we will make this filter easier in the next release. You'll be able to call a method such as "getDecodedParameter" on the SmooksResourceConfiguration, returning a decoded parameter Object. See SmooksResourceConfiguration.
