Class Summary
AbstractResultSet This class is a skeleton for writing non-abstract classes that implement the ResultSet-interface.
AbstractTuple This class is a skeleton-implementation for Tuple.
ArrayTuple This is an Array implementation of the Tuple interface.
AssembledResultSetMetaData This class is a ResultSetMetaData implementation that wraps a given array "columnMetaDatas" of ResultSetMetaData.
BufferedResultSet This class decorates a ResultSet by buffering selected tuples with a bag.
Distinct This abstract class represents the logical operator "Distinct" (the operator for duplicate removal).
FileResultSet The operator for blablabla ...
new FileresultSet("DB1.txt");
Grouper This abstract class represents the logical Operator "Grouper".
Join This abstract class represents the logical operator "Join" (natural Join).
ListTuple Linked list implementation of the Tuple interface.
MergedResultSetMetaData  
Minus This abstract class represents the logical operator "Minus".
NestedLoopsDistinct Nested-loops implementation of the operator "Distinct".
NestedLoopsGrouper  
NestedLoopsJoin  
NestedLoopsMinus Nested-loops implementation of the operator "Minus".
NumberMetaData A skeleton implementation of ResultSetMetaData for Numbers.
Projection The operator for projection (without duplicate removal).
For each tuple of the given resultSet a new tuple will be computed.
ResultSetCursor This class serves a ResultSet as a Cursor.
Selection The operator for selection.
Some tuples of the given ResultSet are selected to the output ResultSet by a specified predicate.
SortBasedDistinct Sort-based implementation of the operator "Distinct".
SortBasedGrouper  
SortBasedMinus Sort-based implementation of the operator "Minus".
Sorter This class sorts the given ResultSet by the specified comparator.
Union The operator for union (without duplicate removal).
VarCharMetaData A skeleton implementation of ResultSetMetaData for VarChars.
