Table Architecture

Table

Base interface for all tables supports following methods:

• map(function) - apply transformation to table rows
• filter(predicate) - filter table rows
• begin(), end() - get iterators to rows
• iterator++ - interface assumes only forward iteration

MappedTable : Table

Table after map transformation. Can apply function lazily.

FilteredTable : Table

Table after filter transformation.

InMemoryTable : Table

Interface of table that is stored in memory. Methods:

• size() - size of table
• operator[] - access table row by index
• iterator-- - interface assumes random access iteration

StreamingTable : Table

Interface of table that is read incrementally.
