the converted number

Throws:

IllegalArgumentException - if the number cannot be converted to a Long

fetchProperty

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

Fetches a long property from the specified configuration.

Specified by:

fetchProperty in class NumberTransformerBase<Long>

Parameters:
