Method Detail

parse

public static String[] parse(String regexp,
                             String string)

Matches a string against a regular expression and returns an array of the substrings corresponding to the groups of the regular expression, or null, if the string does not match the regular expression.

Parameters:

regexp - a regular expression

string - a string

Returns:

an array of the substrings corresponding to the groups of the regular expression, or null, if the string does not match the regular expression

parseAndSetProperties

public static boolean parseAndSetProperties(Object bean,
                                            String regexp,
                                            String string,
                                            String... properties)
                                     throws IntrospectionException

Matches a string against a regular expression and uses the resulting groups (corresponding to portions of the regular expression between braces) for setting properties of a bean. The write method for the i-th property is called with an object of the write method's parameter type, that object is created by calling the type's string constructor with the string of the i-th group.

Parameters:

bean - a bean

regexp - a regular expression

string - a string to match the regular expression against

properties - names of properties of the bean

Returns:

true if the string matched and if the properties could be set

Throws:

IntrospectionException - if the bean could not be introspected
