public class ConditionalText
extends com.openly.dt.ParsingDynamicTag

ConditionalText is a dynamic tag implementation uses argument 1 as the name of a switch parameter. It retrieves the value of the parameter, returns the second argument, as a dynamic tag (either as a DynamicTag class or Params item), if "true" or the third argument, as a dynamic tag, if "false". a String is true if not "", an Integer is true if >0 , and any other object is treated as a String. The result is interpreted as a dynamic tag, unless parameter starts with a quote character, in which case enclosing quotes are stripped and the string is returned.

Conditional Text has a synonym in JSText, "if".

USAGE:

    [[@if(inFrame,"target=_top",@template(noframetarget.tpl)]]     means: if there is a non-empty value for inFrame in params, then replace the tag with "target=_top",  otherwise insert template "noframetarget.tpl"    [[@com.openly.dt.ConditionalText(for,for)]]     means: if there is a non-empty value for "for" in params, then replace the tag with that value,  otherwise insert nothing

2/8/01 fixed non-stripping of quotes when the object==null test was activated
6/21/01 parameter strings passed in by JSText can now have nested tags, so strings are assumed to be templates. commas now protected by quotes
1/10/02 the switch parameter can now be a dynamic tag
11/13/2002 the switch parameter can be an equality test x="1" or x=y. in the first case, params.getString("x") is called and compared to the value in quotes. In the second case params.getString("x") is compared to params.getString("y").
