getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed. ATTENTION! This will create new parameterTypes. For calling already existing parameter types use getParameters().getParameterTypes();

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class DatabaseDataReader

getConnectionEntry

public ConnectionEntry getConnectionEntry()

Specified by:

getConnectionEntry in interface ConnectionProvider

Overrides:

getConnectionEntry in class DatabaseDataReader
