compile_load()

StackMachine Interpreter::compile_load ( const Schema &  tuple_schema, void *  address, const storage::DataLayout &  layout, const Schema &  layout_schema, std::size_t  row_id = 0, std::size_t  tuple_id = 0  )

static

Compile a StackMachine to load a tuple of Schema tuple_schema using a given memory address and a given DataLayout.

Parameters

tuple_schema	the Schema of the tuple to load, specifying the Schema::Identifiers to load
address	the memory address of the Store we are loading from
layout	the DataLayout of the Table we are loading from
layout_schema	the Schema of layout, specifying the Schema::Identifiers present in layout
row_id	the ID of the first row to load
tuple_id	the ID of the tuple used for loading

address	the memory address of the Store we are storing to
layout	the DataLayout of the Table we are storing to
layout_schema	the Schema of layout, specifying the Schema::Identifiers present in layout
row_id	the ID of the first row to store
tuple_id	the ID of the tuple used for storing
