configure

protected void configure(org.apache.avalon.framework.configuration.Configuration conf,
                         java.lang.String confName,
                         java.lang.String nameAttr,
                         java.lang.String valueAttr)
                  throws org.apache.avalon.framework.configuration.ConfigurationException

Setup the association from expressions to a list of patterns. The configuration should look like : <pre> <map:selector name="foo" src="..."> <confName nameAttr="expression" valueAttr="pattern"/> ... others (expression, pattern) associations ... </map:selector> </pre>

Parameters:

conf - the configuration

confName - the name of children of conf that will be used to build associations

nameAttr - the name of the attribute that holds the expression

valueAttr - the name of the attribute that holds the pattern

checkPatterns

protected boolean checkPatterns(java.lang.String expression,
                                java.lang.String value)

Checks if value is a substring of one of the patterns associated to expression

Parameters:

expression - the expression that is selected

value - the value to check

Returns:

true if value matches one of the patterns
