Specified by:

getParameter in interface ParametersCallback

Parameters:

name - parameter name. Providers are allowed (but not required) to ignore a case of the name parameter to comply with their internal model. For example JDBC drivers are case-insensitive to column names.

Returns:

parameter value or null if parameter doesn't exist.
