Method Detail

convert

T convert(String value)

Convert the given configuration keys from it's String representation into the required target type. IMPORTANT NOTE: Multiple instances of this type are ordered in a chain of converters that try to parse/convert a configured value. The first non-null result returned by a converter is used as the final result of the conversion. As a consequence implementations of this class must only return non-null values that are the result of a successful conversion of an entry.

Parameters:

value - the configuration value, not null.

Returns:

the converted value, or null if the value could not be converted. Returning a non-null value will stop the conversion process and return the value as result (converted value).
