the converted number

Throws:

IllegalArgumentException - if the number cannot be converted

fetchProperty

protected Integer fetchProperty(org.apache.commons.configuration.Configuration config,
                                String property,
                                Integer defaultValue)

Fetches a configuration property of type integer.

Specified by:

fetchProperty in class NumberTransformerBase<Integer>

Parameters:

config - the configuration

property - the property to fetch

defaultValue - the default value

Returns:

the property from the configuration
