Method Detail

setReplacement

public void setReplacement(String replacement)

Whenever a match is found, it replaces with this value.

Parameters:

replacement - the replacement string.

apply

public String apply(String target,
                    javax.servlet.http.HttpServletRequest request,
                    javax.servlet.http.HttpServletResponse response)
             throws IOException

Description copied from class: PatternRule

Apply the rule to the request

Specified by:

apply in class PatternRule

Parameters:

target - field to attempt match

request - request object

response - response object

Returns:

The target (possible updated)

Throws:

IOException - exceptions dealing with operating on request or response objects

applyURI

public void applyURI(Request request,
                     String oldURI,
                     String newURI)
              throws IOException

This method will add _query to the requests's queryString and also combine it with existing queryStrings in the request. However it won't take care for duplicate. E.g. if request.getQueryString contains a parameter param1 = true and _query will contain param1=false the result will be param1=true&param1=false. To cover this use case some more complex pattern matching is necessary. We can implement this if there's use cases.

Specified by:

applyURI in interface Rule.ApplyURI

Parameters:

request - the request

oldURI - the old URI

newURI - the new URI

Throws:

IOException - if unable to apply the URI

toString

public String toString()

Returns the replacement string.

Overrides:

toString in class PatternRule
