For a given object, try to find the appropriate reader method and return the value, if set
for the object. If the property is currently not set for the object, an
{@link UnexpectedLiquibaseException} run-time exception occurs.

@param object                        the object to examine
@param propertyName                  the property name for which the value should be read
@return                              the stored value
For a given object try to find the appropriate reader method and return the value if set for the object . If the property is currently not set for the object an { @link UnexpectedLiquibaseException } run - time exception occurs .
