public class ContentRegExParamBuilder

Method Detail

getPatterns

protected Collection<Pattern> getPatterns(Map<String,String> params,
                              javax.servlet.http.HttpServletRequest request)

Implementation for the AbstractContentRegExParamBuilder.getPatterns(Map, HttpServletRequest) method; this will return the configured collection of patterns.

Specified by:

getPatterns in class AbstractContentRegExParamBuilder

Returns:

getGroupNames

protected Set<String> getGroupNames(Pattern pattern)

The default implementation defined by the superclass dynamically finds the group names upon each call to AbstractContentRegExParamBuilder.buildParams(Map, HttpServletRequest). Since we only have static patterns, we predetermine the group names as soon as the patterns are defined (in the setPatterns() method), and simply return them here.

Overrides:

getGroupNames in class AbstractContentRegExParamBuilder

Returns:

getPatterns

public Collection<Pattern> getPatterns()

Get the configured patterns.

Returns:

setPatterns

public void setPatterns(Collection<Pattern> patterns)

Set the patterns used to search the content for parameters. Instead of simply storing the collection of patterns, we also already determine the group names defined in each pattern. These group names will be returned by the overridden getGroupNames(Pattern) method.

Parameters:

patterns -

toString

public String toString()

Provide a useful string representation of this ParamBuilder, showing the content parameter name, the configured patterns, and the output parameters as defined in the patterns.

Overrides:

toString in class Object
