java.lang.String[]	getAliases() Get the aliases for the databinding
ExceptionHandler	getExceptionHandler() Get the handler that can handle exceptions/faults in the databinding-specific way
java.lang.String	getName() The name of a databinding should be case-insensitive and unique
SimpleTypeMapper	getSimpleTypeMapper() Get the type mapper for simple types
WrapperHandler	getWrapperHandler() Provide a WrapperHandler for this databinding
boolean	introspect(DataType dataType, java.lang.annotation.Annotation[] annotations) Introspect and populate information to a DataType model
DataType	introspect(java.lang.Object value) Introspect the data to figure out the corresponding data type
